As in any other branch of modern industry, in metallurgy it is impossible to do without such a very important stage in the production of certain goods as marking. It is thanks to her that it is possible to carry out a strict accounting of all products created at the enterprise, and trace all the movement of goods from production to the warehouse.

Can be done in two ways. First, when marking metals and alloys, hanging labels and self-adhesive labels can be used. Secondly, direct marking on the product can be carried out. Naturally, in metallurgy, the use of a direct marking method is much more preferable, because both labels and labels are not reliable enough.

Direct marking of metals and alloys is carried out using EBS equipment and transmits data such as a barcode, graphic or alphanumeric information.

Essential in the automotive, aircraft and tool industries. Certain data about the product and its manufacturer must be present on metal parts, pipes, watches, lamps, etc.

Metals and alloys should be marked in such a way that the applied information does not damage the surface of the product, therefore, when marking metals, it is best to use inkjet marking equipment. Marking made by the drop-jet method does not cause oxidation and rusting processes on the surface of the product, does not corrode it. Inkjet printers are capable of applying strong, bright, easily readable and durable characters to a metal surface, which are extremely important not only in the process of manufacturing, storing and selling metal products, but also during their further operation.

For example, in the automotive industry, one cannot do without reliable marking of parts due to constantly improving and changing technologies and designs of various materials, parts and assemblies, which entails their division into “old” and “new”. In this case, the durability of the marking plays a very important role , since it is necessary to keep on the parts during the entire warranty period information about all changes available at the time of production of the product, both in its technology and design, as well as on the material and version of this product.

Continuous inkjet printers can be perfectly used for creating markings on stainless steel, iron, brass, androided aluminum and other metals. As a rule, metal marking is a logo, serial number, tabular or bar code.

Modern ink jet markers allow you to easily and quickly perform the necessary marking not only in any conditions, but also at any stage of production and storage of metal products. Using ink jet printers, it is possible to print the necessary information of various heights.

Details

Any metal product must have a personal marking. It is carried out in two ways:

1.Labels and tags

2.Applied directly to the product itself. In the second case, the ideal equipment for deposition is a laser. This is a non-contact marking, it does not spoil the surface at all, it can be applied to a metal sheet or to finished products. It has no consumables and is easy to manage.

Today, in metallurgy, it is impossible to do without marking, as in other areas of modern production. In any industry, product labeling is a very important production step. Thanks to high-quality labeling, a strict accounting of each unit of a product produced by an enterprise and control over its movement not only within the enterprise itself, but also during the sale of a particular product is carried out.

Marking on metal products can be done in two ways.

• Method 1: Self-adhesive labels and hanging labels can be used to mark products made of metals or alloys.
• 2nd method: marking on such products is carried out in a direct way (that is, marking is applied directly to the product itself). It is carried out using laser marking, transferring information such as a barcode, alphanumeric data or graphic images, etc. to the goods.

It is clear that in metallurgy it is more expedient, of course, to use the second option for marking, and there are quite adequate explanations for this. Marking on tags and labels is not reliable: it is erased, it can be easily forged, etc., therefore, almost all large enterprises use the direct method to label their products.

The use of laser metal marking in industry

Marking metal products is extremely important and necessary, for example, in such industries as the aviation industry, automotive industry, in the production of various tools, on pipes, on watches, and so on. Such metal goods must be marked, otherwise tracking, correct assembly and sale will be impossible.

Metal laser marking process

As a rule, in industry, products made of metals and alloys are marked in a non-contact way (that is, without touching the product itself). Thus, when marking on the metal surface of the product, the top layer of the material is removed. The marking made in this way is durable and does not oxidize or rust at all. Laser markers allow you to apply durable, bright, indelible, easily readable information on metal products, which is extremely important not only in the manufacture, storage and sale of metal products, but also during their further operation.

What metals can be marked

The laser marker can be successfully used for marking stainless steel, iron, brass, androided aluminum and other metal alloys. As a rule, metal marking is a logo, serial number, barcode, batch number. Modern laser markers allow you to quickly and easily perform marking in any conditions of the enterprise, as well as at any production stage of manufacturing and storage of metal products.

Due to constantly changing and improving production technologies, for example, in the automotive industry, reliable and high-quality marking of parts is indispensable, since the design features of various parts and assemblies change every year. As a rule, this entails the separation of products into “new” and “old”, thus, the durability of the marking is given the most important role for production. Because during the warranty period it is necessary to keep on the details information about all products available at the time of production, changes in design and technology, as well as about the material and manufacturing option of a particular product.

Several technologies are used to apply a bar code.

The most common and inexpensive printing on self-adhesive materials is self-adhesive sheet labels or self-adhesive rolls.

Printing with a laser or inkjet printer on self-adhesive sheet labels is done just like regular office printing. Bar codes, both linear and 2D, are generated by accounting software or graphic editors. Using a copier, you can print large quantities of barcode labels, but applying a sheet label to products or packaging is a rather laborious operation.

You can simplify the application by using roll materials and applicators. Printing on roll labels with a thermal or thermal transfer label printer. Printing on labels in rolls allows you to print large runs, reprint information and apply barcode labels to products using manual or automatic applicators. Roll materials are represented by a large assortment: thermo-eco, thermo-top, paper, polypropylene, metallized polypropylene, PET tags and PET eyelets, nylon ribbons, satin ribbons.

To apply a barcode on plastic cards, plastic card printers are used. The plastic cards themselves can be supplied in various versions: white, pre-printed in black and white or full color. Depending on the task, a bar code can be applied to each card separately (for a pass) or printed in circulation (for a discount).

Applying a bar code using an ink jet printer. It is used for marking boxes and applying a bar code to the packaging. It is used for marking boxes, applying a bar code to packaging, as well as plastic and metal pipes, metal-roll, plywood, packaging film.

When applying a bar code using a continuous ink jet printer, it is very important to observe the conditions: the surface must be flat, the speed of movement along the conveyor is constant and not very high. You can apply a barcode on almost any material, but not all materials and products will be read by a scanner - many materials glare. On flat and smooth surfaces, linear and 2D codes are applied perfectly.

Direct metal marking and bar code application by impact marking or tracing - DPM.

To print bar codes and text information on film roll materials, specialized built-in thermal transfer printers can be used. The solution is built into a conveyor or packaging line, it can operate in two modes - continuous material supply or start-stop mode.

When packing products manually, it is advantageous to use a workplace based on 1C:. In addition to weighing or counting products, the system provides data exchange and reporting for the 1C:Enterprise central database.

Methods and equipment for applying and reading a barcode

Printing barcodes on packaging or product labels

A barcode can be applied during the production of packaging (printing method) or self-adhesive labels can be used, which are printed using special printing devices (printers). The choice of printer depends on the application using the barcode. To print a barcode on paper documents, it is advisable to choose a conventional laser printer (it is highly desirable that it has built-in support for barcodes). The use of matrix and inkjet printers in this case is not recommended due to the fact that the print must be of sufficiently high quality. If you still decide to use them, then you need to keep in mind that the print quality on a laser, dot matrix or inkjet office printer can significantly affect the ability to read a barcode with a scanner. It is advisable to always check the ease of reading it with the scanner that will be used in real conditions.

Because bar coding is commonly used to label a variety of items, bar codes are often printed on self-adhesive labels in a variety of materials (which are then applied to a variety of surfaces). With a small number of printed labels, you can use the same laser printer and sheet labels. Those who intend to regularly print several hundred or more labels per day should consider purchasing a dedicated label printer. These devices are usually characterized by high performance and a minimum amount of resources expended.

These printers typically use two printing methods: direct thermal and thermal transfer (thermal transfer). The first method is to change the color of the thermal paper from which the label is made when heated by the printer's print head (the same printing method is used by most fax machines). The second allows you to print on plain paper labels (as well as polyester and other synthetic materials). The ink is transferred to the label from a special ink ribbon (ribbon), which is a consumable. This printing method provides a more stable image on the label and is not affected by external factors such as temperature changes, high humidity, direct sunlight, in some cases - chemicals (gasoline, solvents, alcohol-containing substances) and extreme temperatures (from -35 to +90 °С).

Printers operate under the control of a computer running in a Windows or MS DOS environment. The user can easily design his own labels using Windows editors or special label design programs. All printers support many symbologies in hardware, which allows you to print a large number of various barcodes quickly and with high quality.

To determine print quality, barcode verifiers perform a series of control reads and then generate a report that details the key parameters that affect read quality. Portable verifiers are used when it is impossible to bring the barcode to the computer (oversized cargo). Some industrial thermal transfer printers have built-in verifiers, which is useful when doing large print jobs or when you need to achieve optimal barcode quality.

Applying a barcode to a product

Until recently, barcode reading was done with very expensive devices, which prevented the widespread adoption of DPM technologies, as it was associated with high costs and often provided a very low economic effect.

In terms of depth and safety, the marking methods are arranged in ascending order.

Ink jet marking It is based on the application of very small ink drops to specified points on the surface of a moving material, which form the desired pattern. This method is quite high-performance, but the ink has low resistance to adverse factors (abrasives, temperature, etc.), so it is unsuitable for long-term and reliable information storage.

Needle punch marking is based on the mechanical impact of a sharp needle on the surface of the material, which forms depressions in the form of dots that make up a given image. This method is less productive than the previous one, but the resulting pattern is resistant to abrasive and chemical attack, as well as extreme temperatures. Needle punch marking can be done with an electromagnet or compressed air.

Scribe marking- mechanical impactless action of a sharp needle-cutter tightly pressed to the surface of the material. When it is moved, continuous lines are formed that make up the given image as a whole. In terms of performance and resistance to adverse factors, this technology is similar to needle-impact marking.

laser marking based on the change in the color of the surface of the product under the influence of a laser beam. This method has high productivity combined with sufficient resistance to adverse effects (abrasive and temperature).

Etching technology is based on the action of chemical reagents on separate areas free from protection on the surface of the material. With low productivity, this technology can also provide high accuracy and average marking durability.

How is a barcode read?

To read barcodes, special devices called barcode scanners are used. The scanner illuminates the barcode with a light or laser beam and reads the resulting image. After that, it determines the presence of black barcode stripes in the picture. Barcode decoding is performed by a receiving device or an external decoder. If the scanner is equipped with a built-in decoder (it is available in all modern models), then the latter decodes the barcode and transmits information to the receiving device (computer, cash register, etc.) in accordance with the interface signals (RS-232, USB port , PS/2-keyboard break) determined by the scanner model. A multi-interface decoder allows a single scanner to support multiple different interfaces and can connect to a variety of devices.

Barcode scanners are divided into:

• by reading distance - contact and non-contact. Contact scanners read the code when the scanner is brought close to the code (at a distance of 1-2 cm), non-contact - from a distance of 10 to 80 cm (depending on the model). Non-contact scanners provide more convenient work, but are more expensive;
• according to the reading method - to LED CCD scanners (CCD) and laser ones. CCD scanners illuminate the surface area containing the barcode using LEDs and read the image onto a special CCD matrix. They have higher mechanical strength (due to the absence of moving parts) and better performance in reading damaged (poorly printed) codes. Laser scanners illuminate the barcode with a narrow beam of laser light-emitting diode (LED) that unfolds with the help of a rotating mirror. Laser scanners are only non-contact, which is determined by the characteristics of the technology, and have a higher range than CCD scanners;
• according to the method of installation - on manual and stationary. A handheld scanner is a portable device that is connected via a cord to a computer, cash register or other device - a data receiver. To read the code, it is brought to the object marked with a barcode. The stationary scanner is mounted on a fixed base. Barcoded items are brought or fed by a conveyor to a scanner that reads the barcode and transmits the information to the cash register (or computer) via an interface cable.

Fonts and barcode printing programs

Barcodes, like text, exist as fonts. True Type barcode fonts have been created for personal computers running under Windows. They are placed just like any other Windows font, can be used in any Windows application, and can be printed on any printer installed with a Windows driver. Using this method, the barcode can be inserted into any document. The only thing to note is that EAN, UPC, Interleaved 2 of 5 and Code 128 fonts are not as simple as they seem. They use check digits, encode characters in pairs, and require special formatting characters. For this, special auxiliary programs are used. You define the information that you want to encode. The program formats the text to include additional information. The new text must then be copied and pasted into an application using the barcode font. If you use programs that support dynamic link updates (Dynamic Link Libraries, DLL), then it is possible to automate the encoding process.

Similar fonts also exist for DOS applications delivered as Terminate and Stay Ready (TSR) programs. These applications are more difficult to use because the barcode data is only visible as text when you create or edit a barcode. And only at the moment of sending a print job, the specially formatted text is processed by the resident program into a barcode that will be printed.

For printing on a conventional laser, matrix or inkjet printer, there are specialized programs for DOS or Windows. They may contain their own barcode fonts, which, however, are not available to other programs. For Unix systems (mainframe supercomputers), a hardware module containing barcode fonts is used, which is connected to the parallel port. The specially formatted text is converted into a barcode when the data is sent to the printer.
