It is dashboard for some types of LADA sedanall 22 parts in this unit were produced by Kenvox, including plastic, metal, rubber, silicon, silk-screen printing film etc, with very high tolerance requirements 1. Glass, Frame, lighter, Insert and Cover: there are the four biggest parts in this unit, they are made by different plastic material with variant shrinkage rate among one another, and it is not easy to control the dimension precisely for perfect assembly results. 2. Glass: its surface requires much glazed polish like a mirror; meanwhile, since the material is fragile and the surface is non-flat, the ejection should be smooth. Otherwise, the finished parts would be broken while mold or the surface would have traces. 3. Lighter: It is an important component which concern about final optical display. Thus the mold must be mirror polished. Any deviation on dimensions or defects on color and structure is unacceptable. Since the material PMMA is fragile and the surface is non-flat, the ejection is not easy. Any traces or broken is unacceptable. 4. Printing Film: need as many as 12 times?silk-screen printing, the location of printing should be very accurate, any slight deviation is not acceptable at all 5. Arrow: with high technology requirements on silk-screen printing, the light on the arrow should be very well proportioned and even from the end till the head.
