Advantages of laser marking machine for QR code marking of automotive parts

Release time: 2015.05.12 News source: Laser cutting machine | Laser marking machine | Laser engraving machine | Fiber laser marking machine | Laser equipment manufacturer-Dongguan Heli Laser Equipment Co., Ltd. Browse times:
At present, the common automotive parts marking methods on the market are: mold casting, electro-erosion marking, stickers, screen printing, pneumatic marking and laser marking. Among them, although the laser marking technology was born at the latest, it has received widespread attention for its indelibility since its birth.
The main advantage of using lasers for marking automotive parts is that it is a fast, programmable, non-contact process that is durable and generally unaffected by the steps required in the production process and is not subject to The impact of the harsh site environment. Of course, it also has disadvantages, such as the high initial cost of laser marking equipment and insufficient contrast in some applications (such as marking plastic products).

Laser, bar code and two-dimensional code are widely used in automotive parts traceability
Bar codes and two-dimensional codes are popular technologies for traceability of various forms of products today, and are fully applicable to various types of automotive parts. Early car parts marking mainly relied on marking serial numbers on products to meet traceability requirements. After the birth of the bar code, it was quickly applied to the marking of car parts, but its small amount of information and poor fault tolerance did not get a comprehensive popular. This problem was not solved until the birth of two-dimensional code technology.
A QR code is a checkerboard-like 2D graphic that can hold a large amount of information in a very small area. Because 2D code 2D graphics only require a contrast ratio of 50% or lower, the use of 2D code graphics greatly increases the number of laser applications.
The code of the two-dimensional code also has a built-in correction function. Even if part of the code is damaged for some reason, the code can still be read. The two-dimensional code can also use several different forms of decoding and encryption, and place protective devices in the data, making this type of mark more valuable for patented components. 激光切割机 | 激光打标机 | 激光雕刻机 | 光纤激光打标机 | 激光设备品牌生产厂家-东莞市合力激光设备有限公司, 还支持DataMatrix、PDF417、QRCode等二维码技术。 In addition to the automatic generation of barcodes for marking software, laser cutting machines | laser marking machines | laser engraving machines | fiber laser marking machines | laser equipment brand manufacturers-Dongguan Heli Laser Equipment Co., Ltd.
