The quality of the auto parts is crucial to ensure the quality of the whole vehicle, which can be described as “pull one hair and the whole body is affected”. In China, with the vigorous development of the automobile market, the production requirements for auto parts are also more stringent.

It is imminent to establish a quality and safety traceability system for auto parts to realize the life cycle management and defective product recall of parts and auto manufacturers, and eliminate the counterfeit and shoddy events of auto parts and spare parts.

As early as January 2016, the Standard requires laser marking of the key and important parts of the vehicle, that is to say, the manufacturing technology directly marks the surface of the parts to do the “body identification”.

At past, the traceability of auto parts was mainly achieved by marking the serial number on the product. After the birth of the bar code, it was quickly applied to the identification of auto parts. However, the lack of information and poor fault tolerance made it not fully popularized. This problem was not solved until the birth of the QR code technology.

The QR code has a large amount of information storage, and can be inserted into 1817 Chinese characters, 7089 numbers, 4200 English letters, and has a built-in correction function. Even if some information is damaged for some reason, the code can be read. Thus, it is widely used in the traceability of automotive parts.

By scanning the QR code on the part, any product can be traced back to the parts supplier, part batch number, product production time, production personnel and other parameters. What’s more, customers can view at any time. Each product has a unique "electronic ID card", the source can be traced, the direction can be traced, and there is no need to worry about being faked by shoddy parts.

The main advantage of lasers for automotive component marking is that it is a fast, programmable, non-contact process. It is long-lasting and generally unaffected by the steps required in the production process and is not subject to the experience and the impact of the harsh site environment. Laser marking based on two-dimensional code technology can easily realize the traceability of products throughout the life cycle.
