What are the methods for mold polishing?

Today, industrial products in the society have developed towards diversification and high-grade. The manufacturing process requirements are getting higher and higher, so how to improve the quality of the mold that directly affects the quality of the product is the top priority of this process. The quality of the mold is directly related to the quality of the product produced.

In the mold manufacturing process, after the mold is cut into shape, the smoothing and mirroring of the surface is to grind and polish the surface of the mold. After a set of molds are reasonably polished, not only can the quality of the mold be improved, but also the service life of the mold product can be improved.

In the current mold polishing work, the following methods are mainly used:
1. Mechanical polishing
Mechanical polishing is a processing method that smoothes the protruding part of the material surface by cutting, grinding, etc.
2. Chemical polishing
Chemical polishing means that the microscopically convex and concave parts of the mold material on the surface of the mold material are preferentially dissolved in a chemical medium, so as to obtain a smooth and smooth surface.
Three, electrolytic polishing
The principle of electrolytic polishing is similar to that of chemical polishing. It is also used to selectively dissolve the small uneven parts on the surface of the mold material, and then make the surface smooth
Fourth, ultrasonic polishing
Ultrasonic polishing is a relatively advanced method, and there are already advanced ultrasonic polishing machines. It is a processing method that uses the tool section to perform ultrasonic vibration and polishes brittle and hard materials through abrasive suspensions.

At present, the mainstream mold polishing methods commonly used in the market are the above methods. Of course, with the development of technology, there will be better and more advanced methods.
