2.The material uniformity

Die quality, directly related to the quality of products, especially for the film thickness error and optical performance of. The company's production of die head used 40CR steel material, after many processing well-formed processing. Spirochetes in the import of four axis machining center processing, ensuring the mold precision and the spiral flow of the material uniformity, the head of each passage meticulously polished hard chromium plating, increase the die wear and corrosion resistance. The company production of the screw head is 360 degrees rotation continuous, smooth, no leakage, safe and reliable
