What are the common problems when polishing Mold Collapsible Core?

The quality of Mold Collapsible Core polishing will directly affect the aesthetics of the surface and effectively improve the accuracy of the mold. So what are the common problems in mold polishing? 

1. The quality of steel

Uneven surface hardness or differences in characteristics often cause polishing difficulties, and various inclusions and pores in the steel are not conducive to polishing.

2. Heat treatment process

Heat treatment will affect the polishing performance in many aspects. The surface hardened steel has an increased carbon content, and its fine structure is not conducive to polishing.

3. Polishing technology and process equipment

The effect of different hardness on the polishing process. The increase in hardness increases the difficulty of grinding, but the finish after polishing increases. Due to the increase in hardness, the polishing time required to achieve a higher finish needs to increase. At the same time, the increase in hardness and excessive polishing may correspond. Reduce.

Therefore, in order to get the best Mold Collapsible Core during use, it is necessary to understand the polishing problem.
