There are three main factors affecting the polishing effect of moulds:
Quality of mould steel
Non-uniform surface hardness or different characteristics often lead to polishing difficulties, and all kinds of inclusions and pore in steel are not conducive to polishing.
Heat treatment process
Heat treatment affects polishing performance in many ways. The fine structure of surface hardened steel is not conducive to polishing due to the increase of carbon content on the surface. Polishing is difficult because of the increase of small oxide […]
