Common way of car parts marked on the market at present are: die casting, electric corrosion marking, stickers, screen printing, pneumatic and laser marking.
Although the laser marking technology was born at the latest, but since birth to mark it never kill a widely attention.
Will be the main advantage of the laser used for automobile parts tag is, this is a quick, programmable, non-contact technology, its process lasting, usually is not affected by the required steps in the process of production, also not of bad environment on site.
And, of course, it also has shortcomings, such as laser marking equipment initial cost is higher, in some applications (
Such as labeling plastic products)
In marked contrast.
Laser, bar codes and qr codes are widely used in auto parts back bar code and qr code is a hot technology in today's all kinds product traceability, fully applicable to all kinds of auto parts.
Early auto parts mainly depend on the product marking serial number to meet the requirement of traceability, and after the birth of barcode is applied to the identification of auto parts quickly, but the less amount of information, it did not get the comprehensive popularization with fault tolerance.
The problem resolved until the birth of the qr code technology.
Qr code is a similar board form 2 d graphics, can accommodate a lot of information in a very small area.
Because of qr code 2 d graphics requires only read performance at 50% or lower contrast ratio, so the qr code graphics, greatly increased the number of laser application.
Qr code coding also has a built-in correction function, even if for some reason damaged part code, the code is still can read.
Qr code can also be used in several different forms of decoding encryption, placement in the data protection device that makes this type of markup to having the components of the patent right value is bigger.
Besides has the automatic generation of bar code, tag software also supports DataMatrix, PDF417, QRCode qr code technology.
