How to make an inscription on metal

How to engrave metal at home

Applying a pattern to various objects by removing a substance from its surface has been known to mankind for many millennia.

With the advent of new materials, the need arose to develop working methods that allow engraving on objects that are much harder than wood and stone. New technologies make it possible to fully automate the engraving process when applying a design to a metal surface, but for a home craftsman, the most suitable option is to master the manual method of applying a design.

Do-it-yourself metal engraving is possible at home, if you have the tools and a suitable room to perform this type of work.

What is needed for engraving

For manual engraving at home, you will need the following tools and materials:

• Stichel.
• Metal blank.
• A vice or similar device for holding a workpiece stationary.

The blank for applying the pattern can be used from any metal, but for beginning craftsmen it is better to use aluminum or copper.

The graver is a rod up to 120 mm long. One end of this tool is cut at an angle and sharpened, the other is installed in a handle made of wood or plastic.

The graver can be of different shapes and also differ in the width of the working surface. If you do not have this tool, you can make it yourself if you have materials suitable for this purpose.

Making your own gravel

To make a gravel, it is necessary to use tool steel. The metal used in springs and ball bearings is excellent for this purpose. To make a cutting surface, you can use old files and needle files, as well as various cutters that need to be cut into thin strips.

The ideal material for making an engraving pen is P18 steel. From old circles for circular saws you can make a large number of blanks for the production of gravers at home. Next, the working part of the workpiece is sharpened at an angle that will make it possible to make a notch of a certain width on the metal surface.

The handle of the gravel is made of hardwood, and should be of such a width that the master can comfortably hold the tool in his hand. The recommended length of this part of the gravel is usually 50 mm.

A mushroom-shaped handle is the most suitable for making this tool, but you can experiment and make several different options, and in the process choose the most suitable option.

Preparation of the workpiece

First of all, you should select a blank on which the drawing will be displayed. The selected product must be free of rust and chips. To prepare the surface you will need:

• Sandpaper P400.
• GOI paste No. 1 or No. 2

First, the workpiece is polished using sandpaper. Then final polishing is carried out using GOI paste.

To avoid damage to the surface, when carrying out polishing work with GOI paste, it is recommended to use this product only No. 1 or No. 2.

You should also do the following before finishing polishing with this product:

1. Prepare a flannel cloth and moisten it with white spirit
2. Pour GOI paste onto a dampened cloth.
3. Wipe the unwanted area of ​​metal with a cloth to remove large pieces that could scratch the surface.

After such preparation, the workpiece is polished using uniform circular movements. After completing the polishing activities, the metal object must be rinsed in kerosene and dried at room temperature.

The process of engraving on metal

If you are engraving a metal surface for the first time, then before you start applying the main design, it is recommended to practice on an unnecessary piece of metal.

The ideal option for such training is to use a copper plate. A piece of copper should be securely fixed to a wooden board using self-tapping screws with wide heads. When the workpiece is secured, the board is laid on the table, additional lighting is turned on if necessary, the cutting tool is clamped in the right hand, and an even notch is made on the metal surface.

To prevent the hand from slipping when making a straight line, on the surface of the metal plate the thumbs of the left and right hands should be connected and touch the plate where the drawing is made.

The index finger of the right hand, at this time, rests on the tool’s cutter and completely controls the process of drawing lines. It is recommended to first make several straight parallel stripes on the workpiece.

When the smooth areas look good, you can move on to making semicircular lines.

When your hand is already a little full, you can begin to engrave the design on the workpiece. To carry out this work, the metal object must also be securely fixed. For this purpose, a device similar to the self-tapping locking mechanism described above should be made.

To engrave simple figures, initials and other simple images, you can begin immediately after securing the metal object. If you need to make a complex drawing, it is recommended to first transfer the image to the workpiece.

Transferring a complex image to metal

The original method of transferring an image to a metal base is carried out in the following sequence:

1. Varnish is applied to the surface of the metal being processed.
2. Using a soft graphite pencil, an image is drawn on a polyester film that will be engraved on the workpiece.
3. The drawing is covered with tape, pressed over the entire area to the film and carefully removed from it. In this case, the image drawn earlier will remain on the sticky surface of the tape.
4. When the varnish dries, the tape is attached to the metal surface, smoothed with a roller or other soft object, and then removed.

After correctly performing the described steps, a pattern will remain on the product, which can be used for engraving.

Other engraving methods

In addition to the manual engraving method at home, the following methods can be used to change the relief of a metal surface:

1. Chemical engraving is a method that can be easily done at home, even with regular table salt and a phone charger.
2. Using a drill is a great method for home use. The principle of metal removal by this method is similar to manual engraving, but instead of a sercie, a drill or similar device with a rotating thin drill is used.
3. Laser engraving is the most advanced way of applying a design to a metal surface, but equipment for this type of work will be too expensive. The use of this engraving method is justified only when the hobby of drawing designs on metal becomes a profession and brings in a constant income.

Conclusion

How to make engraving on metal and which method to master to perform this type of work, everyone must decide for themselves. To begin with, it is recommended to purchase a professional tool for manual work. After working with hand tools for some time, you can move on to mastering the equipment, which will significantly speed up the engraving process.

It is recommended to purchase metal engraving tools only in specialized stores. When making your own gravers, you should pay attention to the cutting surface of the tool, which must be perfectly sharpened.

A gravel that is not sharp enough and has knocked down corners will not allow you to remove the metal correctly. When working with the tool, you must also be careful, otherwise you can seriously injure yourself.

If such a nuisance has already occurred, then the wound should be disinfected and bandaged.

By taking precautions and using high-quality tools, you can create real handmade masterpieces at home, which can be used not only for personal purposes, but can be sold at special online auctions for the sale of handmade items.

Instructions - how to engrave on metal correctly

In this material I want to tell you about engraving on metal. The stages of engraving on metal are almost no different from those on plexiglass, but there are still some nuances.

Tools and materials

For engraving on metal, we need the same thing as for engraving on plexiglass - the same Dremel and attachments, namely: cone-shaped and spherical .

In this case, a flexible shaft is necessary, because although metal is harder than plexiglass, working with it requires greater delicacy, and when working with aluminum, you cannot do without it at all. If you want to experiment , then you should take a polish.

But take a protective one - no GOI pastes or the like. That seems to be all there is to this point.

Tips before engraving

• First, clear your work area and choose a surface that is large enough to wrap the workpiece without any problems. When engraving metal, you don't need directional light—just regular lighting will suffice.
• The second most important thing is comfort . Sit so that your hand can freely reach the top of the workpiece. Also lay the workpiece and check it for deflection. It may happen that at the most important moment the metal will bend and the cutter will lead in the wrong direction, ruining the whole job.
• Wipe the surface well, remove all dust and get rid of grease.
• Fasten it well . If you have a tripod, great, great. But there are cases when the Dremel lies without fixation, therefore there are two options: either engrave with one eye and look at the tool with the other, or simply tie it to the table with something. For example, I hold the Dremel on my knee - it’s most convenient for me.

So let's get started with the process.

First, we select a design and print one on self-adhesive paper, and the second on plain paper. I'll tell you why the second one later.

Printed design for engraving

On top of everything else, I also had to trace all the lines additionally, from which I learned a useful trick. Next we will figure out the location of the drawing, and after that we will glue it. It is advisable to glue starting from the corner and continuing diagonally. No blistering of the paper directly on the drawing is allowed.

To begin, take a cone-shaped nozzle. The photo shows how it has become frayed during use, but the tip itself is still capable of producing a straight line.

Cone-shaped nozzle on a flexible shaft

We sit down to work, cross ourselves three times and begin. While working, do not get distracted, get irritated or overthink . The most optimal movement of the nozzle will be if you position it at a degree and move it towards a more acute angle. In the figure below, it needs to be moved to the lower right corner.

The process of engraving on metal.

Here are some intermediate photos of the work.

The last photo shows how the paper has come off. I usually remove it under hot water, but this time there wasn't a drop of liquid in the garage, so I was impatient and just tore it off. Anyone who can be more careful should experiment with this matter. You can, for example, paint over all this, getting an original effect. As a result, we have a good, but unfinished picture, which itself looks lonely against a black background.

The first version of engraving on metal

But now we take that same unused drawing and outline on it with a pencil the places where we will “fill in”. After this, we take a spherical nozzle and begin to fill. The result is this:

Engraving on metal with filling

Metal Engraving Tips

• If you need to engrave a long line, start at the bottom and move the Dremel away from you. Somehow the line turns out very smooth. As I say: “With soul.”
• When you first start engraving, take a pen and draw the main lines directly on the drawing, excluding unnecessary ones.
• Very often, paper gets under the cutter and gets chewed, after which the cutter can go in the wrong direction purely mechanically. To avoid this, you should start the line a little further and end a little earlier. Then, during the final revision, you will adjust it.
• If it happens that the entire section is very difficult, then simply put dots on the lines and connect them at the end.
• During pouring, do not randomly scrape off the paint. If the fill line is very large, then you should not fill it progressively. It is best to go from start to finish without stopping the cutter in a separate area.
• Again - don't make very small details. The consequence may be peeling of the paint.

Engraving on metal

Thousands of years ago, humanity mastered the method of drawing on metal. The method was based on removing the top layer of the surface of a substance using improvised methods. With the appearance of metal in human everyday life, the need arose to master a new craft - engraving.

The latest equipment and technological process allow us to create beautiful, unique things. The machine method involves working in automatic mode, which significantly saves time. For the home type of work, it is enough to master the methods of artistic work. The transfer of the design can be done with a laser or a special machine.

Engraving on metal

Main types of metal engraving

The craft called engraving appeared many centuries ago. Items and decorations, custom engravings are passed down through generations. Engraving on metal allows you to give the product an individual look and uniqueness. In practice, there are several types of engraving.

Hand engraving was the first to appear and is in demand for jewelry to this day. It is almost impossible to machine parts with an uneven surface. Inscriptions on rings and other jewelry are mostly done by hand.

The tool for the work is a gravel, a small chisel with a pointed end. Hand engraving makes it look nice and adds value.

The disadvantages of this method are the high price; the work requires the necessary professional skills and craftsmanship.

Hand engraving on metal

With the mechanical method, a special machine is used, a special milling tool is used, which removes part of the top layer from the surface of the product. Simple work, as well as its low cost, made this method almost the most common. The surface of the product must be as smooth as possible and correspond to the dimensions of the equipment frame. High-strength materials are processed with diamond-coated tools.

Laser engraving on metal is a newer way to process products. The speed of work and the availability of technology have made the method the most used type. The product takes on the required design or inscription by burning it with laser engraving.

Laser engraving process on metal

This type has several disadvantages, one of them is that the inscription or design is quickly erased from the product. Laser engraving on jewelry looks aesthetically pleasing; the quality of the work depends on the tool and the skill of the craftsman.

General technology

Carrying out engraving processes involves many types of techniques. The main methods are manual and mechanical, the latter is divided into the categories of defensive and line.

1. A three-dimensional design can be obtained by using defense engraving; deeper processing involves three-dimensional engraving.
2. When performing surface actions, the line technique is used. The process is carried out in several steps, the lines of the processing contour are drawn, and part of the metal is removed from the surface using dashed movements.

Defense technology engravingLine engraving

Carrying out incisive engraving yourself is done with a graver. A special tool can be purchased at art stores. Accessories for the manual process are divided into types:

• Messer - a graver is necessary for making fine lines.
• Engraving with parallel lines is done with a pen marker.

Tools for metal engraving cannot be used without high-quality sharpening of the gravel. For high-quality work, you need to sharpen the tool with a fine-grained whetstone, and then wipe it with a leather cloth.

When working with small objects, you will need a special pillow. You can make this tool with your own hands; material of the same size is connected with a thread along the edges. It is necessary to leave an intermediate space for filling with bulk material or sand. The workpiece is turned inside out, sand is poured into the hole formed, after which the rest of the pillow is sewn up with a stitch.

Using the tool will require careful handling and preliminary skills. You need to use the tool like a regular pen when writing, holding the tool to the side with the thumb of your working hand.

Metal engraving is done by yourself; in cases where the direction of the design or inscription changes, the best option is to turn the pillow in the desired directions.

It is possible to apply a design to metal using laser engraving. A unique piece can be used as a gift or as a signature fitting. Changes in design and inscriptions on metal products are available using technology such as laser engraving.

Color engraving

The drawing is applied in color using a glass-graph, made in the form of a pencil or ink. After engraving, the surface is treated with colorless varnish to preserve the result as long as possible. A clear pattern can be obtained using oil-based paints; before application, the surface is scratched and treated with paint.

Color engraving

Blackening can be achieved without the use of special equipment. Mixed substances of potassium carbonate and sulfur are used, the proportions are one to two. It is necessary to place the mixture of materials on low heat in a convenient container, the process must be closely monitored and the composition must be mixed. After the composition has blackened, the fire is turned off and the mixture is ground in a mortar. The blackening process occurs in several steps:

• The composition is mixed with water in a ratio of one to 9.
• An object prepared for performing actions is lowered into a special container.
• The part is heated until blackening occurs; the material must acquire the required shade.

Before applying the inscription, it is necessary to make a background; such cases do not require varnish treatment. Metal engraving can be done in different shades, just mix special substances.

A solution of zinc chloride and copper sulfate will give the part a dark brown tint; mixing is done 1 to 1 with water. A grayish tint can be obtained from a mixture of 2 g. potash and sulfur, ordinary table salt to a liter of water.

A solution of potassium sulphide in the ratio of grams to 250 grams. water will give the product a red tint.

Blackening engraving

After finishing the activity, the used varnish is removed. There is a technique of blackening, the process is not similar to blackening when engraving on metal. The process can only be carried out mechanically; it is impossible to perform it using improvised objects.

Engraving methods at home

The metal engraving process is performed in several well-known ways. All possible options differ in the necessary tools and skills.

Laser engraving carried out on metal will require the necessary equipment. With small volumes of activity, the cost of purchasing equipment can be considered unacceptable. Laser engraving allows you to display the smallest details during work, the design looks clear, without blots. This type is suitable for entrepreneurs whose craft is their main source of income.

Manual execution will require only a few tools and the presence of chemical compounds. High quality drawing can only be achieved if you have certain skills in this area. The tool for work must be perfectly sharpened and varied in order to perform the activity at a professional level.

Using a special device for applying drawings and inscriptions

Receiving a quality product at the end of the process is the main priority of any master. To do the work yourself, at home, the best option is to purchase a tool called an engraver. The presence of many accessories and devices expand the range of applications and make work convenient. Mechanical engraving is performed using technology.

1. Before engraving, you need to prepare a pattern or drawing. You can mark the product with a thin marker or a sharpened pencil, or you can use carbon paper.
2. The tool must be used in sufficient lighting and work should be done in one direction to avoid chipping and burrs.
3. At the end of the work with the metal, the area of ​​the work is covered with colorless varnish. To consolidate the result, it is possible to use wax, applied in a thin layer to the product.

Hand engraver

The use of a hand engraver or machine drill must be done only with a special tool. The choice of attachments is so large that there is a possibility of mixing up the tool, which will ultimately lead to damage to the product.

Drawing using a set of materials at hand

Various types of engraving at home can be performed using electrochemical action. To use, you will need a set of tools that everyone has at hand.

1. The capacity corresponds to the full size of the product. The part must fit completely, the neck must be as wide as possible for convenient work. For small items, a cut glass is suitable; a glass jar remains the best option.
2. Wires for connection with clamps. It is possible to use a household clothespin with foil clips, but it is better to use special “crocodiles”.

How to engrave on metal

The use of artistic engraving allows you to give any item originality and make it truly unique. In addition, artistic engraving looks very stylish. In this article we will take a closer look at how to engrave on metal and what is needed for this?

5 ways to engrave metal

Modern ways of advertising your own brand (including ways to express individuality) have advanced technologies. Some of the most popular methods in this direction are the following:

• laser sublimation;
• laser engraving of metal;
• sandblasting metal engraving.

Each of these methods has its own characteristics and recommendations for use in specific cases. For example, laser engraving on metal is the most versatile and easy to learn, mechanical engraving is focused on engraving plastic and metal products, but sandblasting technology is more typical for glass products. Laser sublimation allows you to make a color drawing of any complexity and, if necessary, transfer it to printing.

The best engraving specialists usually choose one technique for themselves, improving their skills in it. We will talk about how to engrave on metal, which is necessary at the initial stage, and we will analyze the features of each method.

Laser engraving

This is perhaps the most popular method of engraving on metal due to its ease of use, undemanding use of materials and low cost of equipment.

The laser beam is focused on the object (a system of lenses and mirrors is used for this), as if evaporating the processing material with its intensity. By changing the force of impact, you can even trim the object.

CO2 laser engravers, which operate using infrared radiation emitted by carbon dioxide molecules, have become very popular. The technology is widely used for engraving wooden, glass, plastic, ceramic, leather, and polymer surfaces.

But engraving on metal with such an engraver is possible only when the metal has, for example, brass enamel, anodized aluminum coating, or has another suitable type of coating.

Such engravers will not be able to process a metal product without a coating.

Carbon dioxide laser engravers are the most economical among all types of laser equipment. The price of such a tool depends on its size and power level.

Mechanical engraving

This method is also quite common. It is based on cutting a rotating sharp cutter into a metal coating. One of the varieties of this method is diamond mechanical engraving, which uses a cutter with a diamond tip. This type of engraving is often used when working with jewelry and gift souvenirs.

The advantage of this technology is its versatility, the ability to transform an engraved object in a short time and make it truly unique.

Mechanical engraving can be of two types: manual (pantograph) or computerized. The manual method is still used in engraving jewelry, metal and ceramic tableware. But, for the most part, engraving shops use computerized engravers.

This tool uses software, a control module, and a cutter motor to accurately position the cutter on the material being processed.

Depending on the dimensions of the engraving machine, it can be used both for engraving small objects (souvenirs, jewelry, personalized prizes), and used on an industrial scale with mass production.

Sandblasting

Another method of engraving on metal is based on the impact of an abrasive on the surface being processed. Most often, this material is sand, hence the name of the technology. Abrasive powder is applied under strong pressure to the surface of the material, destroying its surface structure.

This creates a matte finish on the treated area. By changing the intensity of the pressure of the sandblasting machine and the grain level of the sand (powder) itself, you can adjust the level of matting of the surface.

The use of stencils allows you to engrave the smallest details on a product: photos, pictures, company logos.

Applying inscriptions to metal at home

Engraving on metal will help you make a memorable inscription on a metal product dear to your heart or prepare an original gift. Most often, for these purposes, the product is taken to a master engraver. However, it will be much nicer and more interesting to do everything yourself.

You can sign a metal item in the following ways::

1. Using paint applied using a stencil or by hand. This is the simplest, most affordable, but short-lived option.

2. Through mechanical engraving. This can be done using a special tool - an engraver or cutter. However, such work requires certain skills and the ability to write (or draw) clearly and evenly on an unusual surface.

The first time, without prior training, it is quite difficult to complete even a simple inscription on a metal surface. Therefore, if you are not confident in your capabilities, then at the first stage it is better to contact a professional engraving workshop.

We recommend paying attention to the Gravpro company, you can find detailed information about it here.

3. Using a laser, which makes it possible to apply the highest quality inscriptions and drawings, with clearly defined smallest details, but requires expensive equipment.

4. Through an electrochemical process. This option does not require large expenses and outstanding artistic skills, therefore it is considered the simplest and most affordable for use at home.

Working principle of electrochemical engraving

The electrochemical method consists in placing the desired metal part in a special solution, after which it is exposed to current. In this case, the part is the anode, a strong saline solution is the electrolyte, and an additional strip of stainless steel (this can be an ordinary spoon), also placed in a container with the solution, is the cathode.

After exposure to a part with a pre-applied inscription or pattern of electric current, the process of electrochemical etching begins. As a result, the image is firmly “fixed” on the metal.

For the initial application of the inscription, as a rule, a stencil is used.

However, if you have good artistic skills, you can apply the contours of an inscription or design directly onto the metal.

What do you need for metal engraving?

To engrave metal yourself, you will need simple things and devices available in every household: - a current source, which can be played by power supplies from electrical equipment, chargers from mobile phones, car batteries, etc.

; - two wires - it is advisable to equip them with clamps; - iron; - stationery tape; - a thin paper sheet with a glossy surface or self-adhesive film; - a small piece of plasticine; - cotton wool; - a glass of water + 2 teaspoons of salt;

- colorless cosmetic varnish.

Creating engraving on metal: stages

Work begins with preparing the electrolyte. It is poured into a container with a fairly wide neck (preferably a glass). The subsequent process, depending on whether the template will be used or not, can take place in two directions. 1. No template. Having decided on the size of the inscription or design, a transparent varnish is applied to the surface of the part.

When it hardens a little, use a thin tool (it can be a needle or a toothpick) to cut out a design on the surface. After the varnish has completely dried, place the electrodes and a second metal object in salt water. The element to be engraved is connected to “+”, and its neighbor to “-”, after which current is applied.

The time of the operation depends on the size of the product itself and the depth of the inscription. Usually it does not exceed 5 minutes. After completing the process, the remaining varnish is removed from the part, the surface is thoroughly washed and dried. To make the design convex, varnish is not applied to the entire part, but only to the inscription.

In this case, the entire element will be etched, except for the protected contours. 2. With a template. A more time-consuming option, but it allows you to use the most ornate signatures and complex drawings. In preparation for work, you need to find the required drawing or inscription and translate it in a mirror image.

10 ways to print on metal

The first printing on metal was engraving. The appearance of the engraving dates back to the 16th century. It was an artistic painting of watches, weapons, and jewelry. At the same time, engraving began to be used in printing - in the manufacture of plates for transferring type onto paper.

Scope of application

Metal inscriptions can be found anywhere: the doors of a management office, a perfume box, an information plate. The rigid texture and stability of the design are appreciated where the paper medium will quickly lose its appearance. And metal always looks presentable and solid. A diploma printed on a gold or silver sheet will please the eye and emphasize the status of the owner.

Images on metal are bright and realistic

In what other areas is metal printing in demand:

• Production of equipment, cars, exclusive cosmetics and perfumes as design elements and information signs. Metal nameplates contain basic information about the product.
• The advertising industry, and more specifically, outdoor advertising. The iron base for the information board will ensure the reliability and durability of the structure.
• Business segment. Metal badges are more resistant to abrasion than even laminated paper ones, and aluminum information plates and signs on office doors harmoniously complement the interior.
• Production of award products. Diplomas, diplomas, certificates are transferred to metal and framed in a beautiful frame - such an item will not only confirm high merits, but also decorate the office.
• Interior design. Decorators successfully use metal elements to decorate the interiors of dining rooms, kitchens, and living rooms. Photos or thematic images that correspond to the general concept are printed on the sheets.
• Furniture manufacturing. Sheets of metal with printed images decorate pieces of furniture, doors, facades of furniture, and housings of lighting fixtures.
• Decorating metal objects: boxes, rulers, badges, flash drives, key rings.

Interior printing on metal - a successful design experiment

10 metal printing technologies

Let's look at the most popular techniques for applying images to a metal surface.

UV printing

Printing with ultraviolet inks is the only technology in which the ink is baked onto the surface, guaranteeing high resistance to abrasion of the design. The process is no different from applying an image to any other medium - be it paper, cardboard or fabric. A wide-format flatbed UV printer is used. It is possible to work with different surfaces: heating radiators, blinds, gadgets, fireplace screens.

UV printing is used to make metal business cards

Graverton

Full color printing on anodized aluminum plates. The thermal transfer technique is used using an intermediate medium - plain paper with a density of 80 g/m². The secret is in special ink that is fixed to the metal surface. The disadvantage of the technology is the use of prints only indoors, since the design is not very durable. A subtype of technology is Masterton. The difference between them is the composition of the ink.

Sublimation

To transfer an image, you need a special coating of the carrier in the form of a thin film of sublimation varnish. There are two types of this technology:

• inkjet - allows you to obtain a high-resolution print (300 dpi), using an inkjet printer, sublimation paper and sublimation ink;
• laser - a laser printer is used to print on special paper; you can apply images to gold, silver, matte and glossy metal sheets.

Disadvantages of this method: over time, the image fades and fades from the sun. Therefore, you need to protect the product from direct sunlight.

Engraving

There are four known types of engraving:

• manual - using dies of different sizes or a drill, a high-quality drawing is obtained, but the qualifications of the master are important;
• chemical - etching of metal using caustic soda, nitric or hydrochloric acid, ferric chloride; before applying the design, the surface is treated with alcohol varnish;
• mechanical - a classic technique using an engraving machine, advantages - you can make convex and convex designs, disadvantages - the duration of the procedure.
• laser - a modern, cheap, fast, high-precision method of applying designs to metal by burning the surface, the disadvantage is the fragility of the image.

Thermal transfer

This is printing on metal objects using transfer images applied with plastisol inks. To fix it on the surface you need a heat press, operating temperature is about 190 degrees. Fixing time is up to 90 seconds. The plus of the technology is a bright, voluminous and textured image, the minus is abrasion.

Alumajet

Another name is metal photo. This is a method of obtaining a wear-resistant inscription or picture on anodized aluminum plates. After application, the drawing is laminated or coated with a special acrylic varnish.

Metallography

Another name for the technology is photomechanical printing. The principle is the effect of special ink on a layer of oxide film that coats aluminum plates. To fix the design, the product is placed in a chemical solution or a protective coating is applied. The advantage of metallography is the clarity and brightness of the image for 5-7 years. Moreover, neither atmospheric phenomena nor aggressive environments affect the quality of the picture in any way.

Metal graphics on information plates

Alumamark

The technology is based on the use of a carbon laser. Due to exposure to high frequency energy, the metal surface turns black, but the surface remains smooth. Alumamark is used in the manufacture of information signs for outdoor placement, since the design retains its clarity and brightness for a long time.

Pad printing

The pattern is transferred using a printing form and an elastic tampon. The latter is dipped into ink and comes into contact with the printed elements, creating an image on the metal surface. The technology is used in the case of complex terrain of the treated surface. It can cope where silk-screen printing or sublimation is not suitable. The disadvantage of pad printing is the small working area, which means you won’t get large images.

Pad printing on a relief dial

Silkscreen printing

The process involves special paints and stencil paper. You can use regular multi-colored, metallic, or fluorescent inks. The disadvantage of the technology is that the surface must be flat and smooth, hence the limited application of this method. Most often these are outdoor advertising, elements for display windows and interiors, and nameplates for various products.

Results

• Metal printing is used in many areas: in mechanical and instrument making, advertising industry, cosmetology and perfumery, interior design, furniture production.
• There are many ways to apply an image to metal; the choice depends on the type of surface, requirements for the design and operating conditions of the product.
• The most popular technologies for color printing on metal are graverton, sublimation and UV printing.

What equipment is used for engraving on metal?

The ability to paint on metal appeared many years ago. The decorative processing method involves removing the surface layer of the material along a pre-prepared contour using various devices. Engraving on metal is done using automated equipment and special tools.

Laser sublimation method

The technology involves making metal engravings using a color printer. Drawing process:

1. Select an image and print it using a color printer.
2. Place the image on the item being processed. Under the influence of high temperature, the paint is transferred to the surface being treated.

Laser sublimation is used to work with various materials. Most often, examples of this technology can be seen on mugs, plates, T-shirts and other things.

Steel engraving technology

Engraving involves various processes, equipment and tools. They can be divided into two types - mechanical (machines) and manual (hand and power tools) engraving. Mechanical is divided into two more subgroups:

1. Defense - This method is used to create large designs.
2. Hatching is a method of processing the surface of a product. Initially, the contour is applied, and then the metal layer is removed.

How to choose equipment

When choosing laser equipment for metal engraving, you need to pay attention to a number of factors:

1. The material from which the guides, bed and working part are made. The structure should not be bent, have cracks or dents.
2. Check the operation of the laser upon purchase.
3. Control Panel. It is better to buy a machine equipped with a CNC system.

When choosing gas emitters that work with CO2, you should take into account the material from which the working part of the equipment is made. Chinese models use glass emitters. More expensive machines use lasers made of metal and ceramics.

Drawing a drawing using a handy set of materials

Engraving can be done using manual tools. Metal surface processing process:

1. Prepare a container that is larger in size than the workpiece being processed.
2. A design is scratched onto the part with a needle. The top is coated with colorless varnish.
3. A positive wire is attached to the product. At the same time, the minus should be placed in a separate glass of water.

The etching process takes place. After this you need to remove the remaining varnish from the part.

Engraving on a metal object with a drill

Experts know how to engrave metal using a drill. However, this power tool is expensive and it is not advisable to buy it for one-time processing.

When working with a drill, the working part of the power tool removes a layer of metal using special attachments.
The equipment comes complete with the machine. Before you start working with this power tool, you need to test it on unnecessary workpieces. Engraving on the spoon. drill + engraver.

Metal engraving using various equipment

During the development of technologies, equipment and engraving skills, many techniques for decorative metal processing have appeared:

1. To make a beautiful inscription or drawing, laser systems are used.
2. A tetrahedral recess can be made with a diamond cutter.
3. It is more convenient to process voluminous parts with a conventional milling machine.

A small engraver is suitable for a home workshop.

Engraving on wedding rings

Engraving of wedding rings has some features:

1. To apply an inscription to the surface of the ring, it must be of a certain width.
2. The softer the metal, the easier it is for the master to work with it.

You can process the side edges of the ring if their width allows it.
Hand engraved wedding rings.

Engraving in production

Metal engraving in production is not much different from the procedure carried out at home. Initially, the working surface is cleaned and degreased. After this, it is tinted with a solution of sulfuric acid. Next, the contour is outlined with a metal needle. The engraver does the bulk of the work. When the main work is completed, the surface is covered with colorless varnish.

Engraving on metal is done in various ways. A variety of equipment and tools are used for this. There is no need to buy expensive equipment to decorate a metal surface.

Engraving on metal: application and types

09.06.2019

Today's equipment and technical equipment helps to create aesthetic and versatile paintings both with your own hands and with the help of special devices. In the article we will analyze what metal engraving is, how and with what it is done, types, techniques and methods of applying drawings. This method transforms an everyday item into a striking and original creation that makes an excellent gift or keepsake.

What is the procedure

Engraving is one of the ancient methods of finishing metal surfaces. Initially, it was used to add sophistication to household items, after which things were passed on from generation to generation. Despite the fact that this is an ancient art, today it is actively used for both personal and public purposes (decorating streets, city monuments, etc.).

Previously, painting was carried out exclusively by hand, without the help of special equipment. Now, for this purpose, various devices and devices are used that make it possible to create any pattern, inscription or picture. Depending on what is used to engrave on metal and how exactly to engrave (choice of technique), different results are obtained. Therefore, it is worth familiarizing yourself with the available methods, since each of them has its own characteristics.

Description of technologies

The rapid development of this craft has led to the fact that there are several different ways of applying an image to a metal surface. If initially only the hands of a master and simple improvised means were used to realize fantasies, today engraving machines and even lasers are used for this.

Manual

This type is often called artistic, since it is extremely difficult to engrave metal by hand. This is a labor-intensive and time-consuming process that requires the master to have special skills, knowledge and patience.

To create the required design or inscription, only a cutting steel tool is used - a graver. This is a special cutter for drawing lines and points of various indentations, which are later turned into a picture.

Such work is considered exclusive, and therefore is of particular value to people who want to get a unique thing of its kind or a creation by a famous master.

Mechanical

Mechanical engraving on metal is popular because it is particularly durable - it is almost impossible to remove or erase the design. It is realized with a sharply sharpened rotating cutter by cutting material that has an exclusively flat surface.

The cutter is located inside the engraving machine, which allows you to obtain three-dimensional and relief designs. The result depends on the depth of penetration of the drill, the use of various cliches (taking into account the characteristics of the cutter) and the skill of the person.

The main advantages of this type are:

• Guarantee of high accuracy and obtaining the desired result while achieving the desired realism.
• Long service life. The created drawings do not lose their original appearance even after several decades and under unfavorable external conditions.
• Ability to create three-dimensional images.

A subtype of the mechanical method is the diamond method, which has some differences. In it, the cutter performs striking movements on the surface, as a result of which a certain ornament is formed. After pressing the diamond needle, microscopic dots are formed, due to which the resulting product receives a specific shine. A diamond cutter can cope with even complex tasks, but a perfectly flat surface is a prerequisite.

Sandblasting

This type has another name - abrasive processing. Engraved inscriptions or other images on metal are applied by etching the top layer of the product with sand or other abrasive powdery substances. They are sprayed with a powerful air flow, resulting in a matting effect. The use of special stencils allows you to obtain not only patterns, drawings or inscriptions, but even photographs.

This type of image application requires sandblasting systems, a mask and an air compressor. Most professionals prefer medium-sized closed units because they filter dust. Also, implementing this technology will require a lot of free space, since engraving on metal using the sandblasting method is only possible with an air compressor, which takes up a lot of space and makes a lot of noise.

Laser sublimation

This type involves the use of a color printer, special cartridges, sublimation paper and a heat press for coloring metal materials. To get the desired image, first of all, you need to print it. The resulting transfer is placed on top of the product, after which the latter is exposed to high temperatures, which promote coloring and the transition of substances from a solid to a gaseous state.

Deep laser engraving on metal is characterized by productivity and practicality, which is especially important for business, for example, for souvenirs when applying photographs. It simultaneously combines high speed, mass production, accuracy, low cost and excellent quality.

This technique involves the use of a focused laser beam. It allows you to adjust the laser power, which gives the image a different tonality and relief.

In addition, the resulting pattern is preserved for many years and does not deform under the influence of water or moisture.

Different laser powers for metal engraving allow you to create sophisticated and complex patterns that have the required depth. Laser engraving involves removing the outer layer of the metal surface, which is important to consider during the work process. Laser contour engraving stands out separately, implying the drawing of exclusively contours. In most cases, this technique is used for processing coins, awards and other souvenirs. The main advantages of the laser are:

• Ability to work on finished products.
• Unlimited number of processed copies.
• Low price of service and excellent quality.
• There is no need to install supports and foundations.
• The ability to apply sketches even to hard-to-reach parts of the product.
• High precision, thanks to which the products are distinguished by realism and excellent reproduction of even small patterns.

Colored engraving on metal

The transfer of images of different colors occurs using a glassograph made in the form of a pencil or ink. After engraving, the workpiece is coated with colorless varnish in order to preserve the resulting effect in its original form for a long time. To ensure clarity, oil-based paints are used on the metal product.

To achieve a rich black shade, you don’t have to resort to professional equipment. For this purpose, you can use a mixture of potassium carbonate and sulfur in a 1:2 ratio. These substances are heated over low heat with constant stirring. After the composition has noticeably blackened, it is removed from the heat and the mixture is ground in a mortar.

How to engrave on black metal:

1. Mix the composition with water in a ratio of 1:9.
2. Place the desired item into a previously prepared container.
3. Heat the parts until black (you should get the desired color shade).

How to engrave on metal with an engraver

You can work with the engraver even at home. The workplace should be spacious and well lit. Before starting work, a sketch is applied to the surface of the product with a regular pencil, marker or copy sheet. After this, patterns are cut out along the drawn lines. It is important to ensure that the cutters go in the same direction. The final stage is treatment with a transparent fixing varnish or wax.

How to engrave metal using CNC machines

CNC milling machines are actively used to create memorable metal souvenirs. They make it possible to significantly increase productivity and speed up the workflow. Stainless steel is especially popular because it is durable, aesthetically pleasing, affordable, resistant to corrosion and temporary wear. The machines used have special fastening systems for workpieces of non-standard dimensions.

Today, metal engraving on CNC machines is in high demand in the restaurant business. The presence of a logo on cutlery gives status and leaves a pleasant impression on guests of the establishment. The process of applying an image on a milling machine occurs in several stages:

1. Preparing a drawing in a special program.
2. Drawing up a route for the cutter. At this stage, you need to pay special attention to the selection of the cutter and its rotation frequency. They also select the area on which the sketch of the future painting or inscription will be located.
3. Fixing the workpiece on the machine. If necessary, a special lubricant is applied on top to ensure better results.
4. Fastening the cutter in the spindle using a collet having the required diameter.
5. Checking the fluid level in the mechanism.
6. machine control programs and completion of automated work.

There are many ways to apply images to souvenirs and gift products. However, metal engraving has enjoyed success for many years.

In addition to creating such masterpieces with the hands of a master, you can use high-tech devices that provide high accuracy and excellent quality of the printed image. They are able to create any inscriptions and even real artistic paintings that are beyond the control of human skills. The automated system independently sets the correct depth and also determines what laser power is needed for engraving metal and applying photos (using the laser technique).

To get an original, high-quality drawing, contact the Sarmat company. Our specialists will create a unique product for you in the shortest possible time using a laser engraving machine in exact accordance with your wishes.

Do-it-yourself engraving can become a profitable and interesting business if you really want it.

You can decorate small metal objects using engraving yourself at home. This activity will arouse the respect and envy of friends and acquaintances. In Zlatoust, thousands of craftsmen practice this craft at home. Engraved items are expensive.

A saber costs approximately 300 thousand rubles, a hunting knife costs up to 100 thousand (photo No. 1). Agree, this is good money.

How to make engraving on metal at home with your own hands? For this lesson you need to prepare the simplest equipment that can be found in any house, in any apartment.

Let's start experiments

Decorative patterns using the engraving method are applied to plates, knives, pistols, sabers, medals, cups, and apartment numbers. All patterns and inscriptions are preserved almost forever and do not require expensive and rare consumables or special equipment for execution. The design can be applied to steel, aluminum, brass, copper, and metal alloys. The method does not pollute the environment. It is impossible to wash off or erase the drawing using conventional methods and means.

It is recommended to start by applying simple inscriptions on cutlery. Relatives and friends may appreciate such a gift. You need to prepare for work (photo No. 4).

Photo 2. Engraved wedding rings, the wedding date and the initials of the bride and groom are usually written on them.

1. Nail polish that my wife doesn't really need.
2. Toothpick with sharp tips.
3. You may need an ordinary match.
4. Salt.
5. Charger for car battery. It can be successfully replaced by charging from a mobile phone.
6. Glass or porcelain dishes in the form of a glass, mug or jar.
7. Nail polish remover.

The work is done in this order:

1. Take a spoon and cover it with nail polish. The entire surface must be varnished very carefully, otherwise there will be defects in the work.
2. Using a match or toothpick, a pattern, name, or other image is scratched through the layer of varnish.
3. Pour 2 tablespoons of salt into a glass glass or jar. Some people add a spoonful of salt and a spoonful of soda.
4. Water is poured into the vessel, the salt is thoroughly stirred until completely dissolved.
5. We connect a car or other charger with the positive terminal to the product being processed, and the negative terminal to any metal object that will be placed in a vessel with water. This item could be another spoon, a piece of thick wire, or a metal plate.
6. The rectifier is connected to the network. Almost immediately, an etching reaction will begin in the glass with darkening of the liquid. It lasts 1-5 minutes. It depends on the magnitude of the current. The product is checked periodically. After reaching the desired etching depth, it is removed from the container.
7. The varnish is washed off with nail polish remover. The result should look something like this (photo No. 3).

Photo 3. Personalized engraved spoons and, interestingly, engraving can be done on various metal objects in a simple home environment.

In this way you can process any metal objects at home. If you make an inscription with varnish, it will be convex on the etched background. For better quality work, it is recommended to purchase a special tool - an engraver.

It can operate from the electrical network and from built-in batteries. The kit usually comes with drills of different shapes. They can work on glass, plastics and other materials. Engraved wedding rings are an excellent gift for newlyweds (photo No. 2).

But you can do this yourself only when you are completely confident in the result of the work.

Glass engraving

Photo 4. For home engraving you will need regular salt, nail polish, nail polish cleaner and a glass of water.

Do-it-yourself engraving on the glass surface is done chemically and mechanically. The mechanical method involves the use of a nozzle that is driven by an electric motor. Procedure:

1. Using a dark marker, the drawing is transferred to the glass.
2. A damp sponge is applied to the image on the glass. This must be done carefully so as not to smudge the drawing.
3. When working, you must use safety glasses.
4. After completing the drawing, it is washed and examined for gaps. If necessary, missed places are processed again.

Engraving with a drill

The principle of do-it-yourself engraving can be seen in the dentist's office. The special tip is held in the hand in the same way as a regular pen when writing. The pattern can be applied to any object: a ring, a mirror, a motorcycle, a sign, etc. You can engrave a portrait or any other image.

We must not forget that the color of engraving on glass, ceramics, stone, porcelain is always white. But it can be carefully coated with silver, gold and any other waterproof paint. The effect can exceed all expectations.

Drawings and patterns can be applied to wood coated with a layer of paint, to plastic, silver, plastic.

Manual work requires patience and certain skills that develop over time. The skill is honed over the years.

Incisive engraving

Photo 5. Master's kit is a set of tools and materials that is always at hand for a professional engraver.

There is a type of hand engraving, which is usually called incisor engraving. It is performed using special cutters - gravers (photo No. 5). There can be different numbers of gravers. Some allow you to make the finest lines, others allow you to make several parallel cuts at the same time. Experienced engravers use this tool.

Stichels need to be able to be sharpened correctly and brought to working condition. Beginner engravers may not be able to do this. Do-it-yourself engraving, especially on metal, is an ancient art. Cold steel, and then firearms, decorated in this way are considered especially valuable and of high quality.

Absolutely anyone can try engraving on small objects like cutlery and knives at home.

How to make an inscription on metal - Metalist's Handbook

Applying a pattern to various objects by removing a substance from its surface has been known to mankind for many millennia.

With the advent of new materials, the need arose to develop working methods that allow engraving on objects that are much harder than wood and stone.

New technologies make it possible to fully automate the engraving process when applying a design to a metal surface, but for a home craftsman, the most suitable option is to master the manual method of applying a design.

Do-it-yourself metal engraving is possible at home, if you have the tools and a suitable room to perform this type of work.
