How to print marks or barcode technology on castings?

Printing marks on castings can be made with concave or embossed characters on some non-machined flat surfaces when making the mold of castings, but you want to make barcodes.

It's not easy, and very few people do it.

Printing marks, barcodes, and other patterns or characters on cast iron can be achieved through coding technology. If you're a company, how to print patterns or characters on cast iron in large quantities depends on the specific situation on your side. With the development of inkjet printer technology, the ink adhesion of ink inkjet printers has been greatly improved, and there is no longer any difficulty in ink coding on metal materials.

At present, small character inkjet printers, large character inkjet printers, UV high-resolution inkjet printers, laser inkjet printers, etc., all have a wide range of specific applications in metal inkjet coding. If your company needs to mark the permanent and immutable identification information on the metal material, you can choose the fiber laser coding equipment; If your company needs to print the logo information with a font height greater than 18mm on the outer packaging made of metal, or on a large metal workpiece (such as a coarse water pipe), you can choose a large-character ink inkjet printer; If your company wants to print ink information on metal materials that dry instantly and has very good adhesion, you can choose a UV high-resolution inkjet printer. If you want to print small font information on a single piece of metal and you want to do it without etching the metal surface, you can use a small ink printer.

In summary, the choice of coding equipment depends on your company's requirements for the specifications and characteristics of the coded content. In terms of the selection of inkjet equipment, you can consult Shanghai Yinma logo shares, the company is one of the top ten brands of inkjet printers in China, the production and sales of the above types of inkjet printers, with a number of national patents in inkjet printer technology, serving thousands of domestic and foreign enterprise customers, including many metal products industry enterprise customers.

If you cast a sand mold, you can do a good job of word molding, put it when modeling, and there will be words after pouring.

If it is a casting that has been cleaned, it can be stamped, or affixed with a barcode that is resistant to high temperature (there is a professional provider to solve this problem).

It can be set up in advance with a metal mold; When using a wooden mold, you can put a mark on the modeling, and it will naturally have it after pouring!

There are a lot of secrets hidden in barcodes

Many products in supermarkets are printed with parallel stripes of different widths and black on the outer packaging, which is the ID card of the goods. Each commodity has only one unique commodity barcode in the world, when identifying it.

UPC-A 1972, EAN-13 1973 can only be said to be an approximate time, it should be 79 years later, after all, before that, the country was... When.

The first product to be marked with a barcode was Wrigley oral chewing gum? Barcode technology was born in the 20s of the 20th century and was born in Westin DAO

In House's lab? An inventor named John Comand "whimsically" wanted to automate the sorting of postal documents?

It was not until 1949 that the invention of the omnidirectional barcode symbol invented by Noam Woodland and Bernard Sylvo was recorded for the first time in patent documents.

After the advent of two-dimensional barcode, the speed of data collection and information processing has been improved, the work efficiency has been improved, and it has made a great contribution to the scientific and modern management. Bar code.

Barcode technology is barcode auto-identification

tech). Barcode technology is an automatic symbol recognition technology produced and developed on the basis of contemporary information technology. It integrates the functions of symbol encoding, data collection, automatic identification, input, and storage information, which can effectively solve the problem of collecting and automatically entering a large amount of data in the logistics process.

Barcode technology has the following characteristics:

1) Reliable and accurate, (2) Fast data input speed, (3) Economical and cheap, (4) Flexible and practical, (5) Large degree of freedom, (6) Non-replicable (anti-counterfeiting). 2 positions.

The product barcode is specified by the International Article Number Association (GPI) and is used to represent the barcode identification of retail goods, non-retail goods, logistics units, and the location of participants.

Specifically, a barcode is a mark consisting of a set of regularly arranged bars, empty combinations, and their corresponding recognizable characters. In the commodity barcode, the combination of bars and empty parts is called the barcode symbol, and its corresponding identification character for people is the commodity identification represented by the barcode symbol. Barcode symbols have the characteristics of simple operation, fast information collection speed, large amount of information collection, high reliability and low cost.

Barcode technology is born with the development and application of computer and information technology, it is a new type of technology integrating coding, printing, identification, data collection and processing.

The use of barcode scanning is a major trend in the future market circulation. In order to enable the free and extensive circulation of goods in the world, enterprises must follow the relevant regulations of commodity bar code management, whether it is design and production, apply for registration or use commodity barcode.

Including the standard version of the product barcode (EAN-13 barcode) and the shortened version of the product barcode (EAN-8 barcode).

Standard product barcode: EAN-13

The structure of the standard product barcode.

The standard version of the product barcode represents the ** composed of 13 digits, and its structure is as follows:

Structure 1: x13x12x11x10x9x8x7 x6x5x4x3x2 x1, wherein: x13 ......x7 Vendor Identification**; x6 ……x2 indicates the commodity item**; x1 check digit.

Structure 2: x13x12x11x10x9x8x7 x6 x5x4x3x2 x1. Where:

x13 ……x6 Vendor Identification**; x5 ……x2 indicates the commodity item**; x1 check digit. When x13x12x11 is , its ** structure is the same as that of structure; When x13x12x11 is 692, its ** structure is the same as structure two.

Checksum calculation.

Refer to the methods specified in the GB 12904 "General Commodity Barcode" national standard.

Shortened product barcode: EAN-8

The shortened version of the product barcode consists of 8 digits, and its structure is as follows:

x8x7 x6 x5x4x3x2 x1；Among them: x8x7 x6: its meaning is the same as the x13x12x11 of the standard version of the product barcode; x5x4x3x2：

Represents the commodity item**, which is uniformly assigned by the EAN coding organization. In China, it is uniformly distributed by the China Article Coding Center; x1 check digit.

When calculating, it is necessary to add 5 "0s" before the shortened version of the product barcode, and then calculate according to the calculation method of the standard version of the product barcode check code.

Commodity barcode refers to a set of rules that are arranged in a row.

The symbol composed of bar, space and its corresponding characters is used to represent a certain commodity information. One of the strips is dark and empty is nanocolor, which is used for scanning and reading of barcode reading equipment. Its corresponding character consists of a set of Arabic numerals, which can be read directly or used by a keyboard to enter data into a computer.

This set of bars, blanks, and corresponding characters represent the same information. At present, the commonly used symbology in the world is EAN barcode, UPC barcode, two-five barcode, cross two-five barcode, Kudeba barcode, three-nine barcode and 128 barcode, etc., and the most commonly used on the product is the EAN commodity barcode. EAN commodity barcode, also known as universal commodity barcode, is developed by the International Article Number Association, commonly used all over the world, and is currently the most widely used commodity barcode in the world.

At present, China is also using this commodity barcode in China. There are two types of EAN product barcodes: EAN 13 (standard version) and EAN 8 (shortened version).
