Introduction to metal bar codes

The metal bar code uses metal as the substrate or production material of the bar code, which can withstand high and low temperature, acid and alkali resistance, and long service life.  
The current metal bar code production process can be roughly dividedEtching, lithography, and special printing. The metal bar code for photoprinting can be produced on site for easy use, but its substrate is subject to certain limitations (because the bar code recognition principle is based on the contrast between bars and spaces ), the reading rate is not high, the reading speed is low, and the cost is high. If the image is complicated, the production speed is slow. The metal bar code of special printing is opposite to the metal bar code of photoprinting, but its wear resistance is low. Etching metal barcode not only has the advantages of special printed metal barcode, but also has strong anti-wear performance.  
Currently, metal bar codes are widely used in asset management, vehicle production line management, and other fields.  
The metal bar code recognition distance is 0.3 m ~ 5 m   ; Maximum bar code width 0.2   ; The thickness of the metal bar code is 0.06 ~ 0.20 , Light weight, its toughness is higher than the paper code, and the bending degree is the same as the paper Code Sign, can bear a certain force of external things on it rubbing and hitting, without affecting its reading effect. In production, you can create serial numbers or different content bar codes.
  Corrosion resistance and high temperature resistance of metal bar code labels (-40 ℃ ~ 200 ℃ ) , Wind resistance, rain, snow erosion and sun exposure, long life 15-20 Is currently the only thin and tough bar code that can be used in outdoor environments for a long time.Metal bar codes can be commonly used Laser Scanner Read-Only, You can also use CCD Pen type Reader or trough ReaderTo read
The metal bar code system can be widely used in automatic control, detection, and automatic management, such as transportation tools, automobiles, motorcycles, and bicycles for registration, billing, and theft; used for mechanical products, electronic products, medical devices, pressure vessels, and weapons **** Management System of military warehouses; important licenses, and confidential registration and management of credit cards.  
  In the field of anti-counterfeiting, it is difficult to copy and copy metal bar codes because of its unique equipment and complex technology. At the same time, this technology is different from other general technologies, it is a patent monopoly technology established by the State Bureau of Technical Supervision, so it is not easy to lose. The internal information of a metal bar code can be changed based on the user's needs, and each metal bar code can be assigned different content, which cannot be decrypted. The metal bar code is pasted on the surface of the object. In anti-counterfeiting, the counterfeit products without metal bar codes can be distinguished from the intuitive vision, and the internal information can be identified by the automatic identification technology, this allows law enforcement and consumers to easily distinguish counterfeit and shoddy products.  
  The metal bar code is evaluated " Reaching the international advanced level ; Has been named ; National Torch Program ; National-level new products
