The polishing in the plastic mold fabrication

In the mold fabrication industry, the main polishing method is the mechanical way, depend on cutting, grinding,rubbing the metal surfaces, to get even surfaces.

The part appearances are often asked the mirror effect, which is divided into 4 levels, A0=Ra0.008μm，A1= Ra0.016μm，A2=Ra0.032μm，A3=Ra0.063μm

To obtain high-quality polished effect, the most important thing is to have a high quality of stone, sandpaper and diamond grinding paste polishing tools and aids. Polishing procedures selected depend on the surface condition after the pre-processing, such as machining, EDM, grinding, etc.
