Abstract: Taking the die parts for steering wheels as an example, the faults of chemical etching process that used to form the surface dermatoglyph of die parts were analyzed. The advantages of using laser engraving technology processing and the key technology were elaborated, which changed the steering wheel surface dermatoglyph design from passive to active mode, It could be designed and manufactured by using 3D technology, and was no longer restricted to processing. It provided the possibility for the design of innovative elements on the surface of the wheel surface dermatoglyph, also provided a reference for other enterprises to introduce the laser engraving technology.
