Polish Way for Mold

Polish Way for Mold

1.Mechanical polishing : reach to a surface roughness of Ra0.008um

2.Chemical polishing : usually a couple of Ra10um

3.Electrolytic polishing : compared to the chemical one, electrolytic polishing could eliminate the negative effect of cathodic reaction;

4.Ultrasonic polishing : the cavitation effect of ultrasonic wave in liquid can inhibit the corrosion process, which is beneficial o surface lighting.

5.Float polishing

6.Megnetic abrasive polishing : high efficiency, good quality, the processing conditions are easy to control. With proper material, the surface roughness could be reached to Ra0.1um.
