With the increasing speed of vehicle, the security problems have been though highly day by day. In the 1960s, America announced the first regulation about the car recall, called the Security Acts of National Traffic and Motor Vehicle, which raised the strict demand of traceability of auto parts, and it lifts the curtain on Auto Parts Laser Marking Machine development. 

So far, the common marking ways of auto parts are die castings, electric corrosion marking machine, adhesive sticker, silk-screen printing, pneumatic marking and laser marking machine. Most of us have no attention on the buttons used in the car, such as the buttons for heating, defrosting, A/C, voice controller and broadcasting, which have been printed with ink. However the prints of ink jet will disappear after the constant use. Vehicle manufacturers are not willing to face the trouble, therefore, they are seeking for a brand new way to make the different prints marked on the buttons permanently. At last, the Auto Parts Laser Marking Machine naturally becomes the best choice. 

 

Even though the birth of technology of laser marking is relative late, it attracts much attention after birth with the permanence of marking. The main advantages of laser marking used in auto parts are as follow, it’s an art which is high-speed, programmable, contactless, and it owns the permanence and will not influenced by the  product process and bad environment. While it owns the disadvantages of high-cost of purchasing laser equipment and the contrast ratio is insufficient in the some applications.
