Mold polishing, tell me what methods you have used.

Mold polishing not only increases the beauty of the workpiece, improves the corrosion resistance and wear resistance of the material surface, but also makes the plastic product easy to demould and reduces the production injection cycle. Therefore, polishing is a very important process in the process of making plastic molds. The main methods are as follows:

chemical polishing

mechanical polishing

electropolishing

Ultrasonic polishing

Fluid polishing

Hand grinding and polishing

Magnetic grinding and polishing

Diamond grinding and polishing

Polishing is only a subsequent process, so the polishing method and process can only affect the quality of polishing process. Whether there is perfect polishing depends on the quality of die steel, surface condition before polishing and heat treatment process.

High quality die steel is the premise of better polishing quality. Uneven hardness of steel surface, different properties of steel, impurities and pores are the culprit of polishing failure.
