First point: wear resistance   When the billet is plastic denatured in the mold cavity, it moves and slides along the outer surface of the mold cavity, which causes severe conflict between the outer surface of the mold cavity and the blank, and then leads to the failure of the mold due to wear and tear. So the

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

Mold, industrial production used for injection, blow molding, extrusion, die casting or forging, forming, smelting, stamping and other methods to obtain the required products of various molds and tools. In short, the mold is a tool used to make molding objects. This tool is composed of various parts, and different molds are composed of different

According to the forming method, plastics can be divided into thermoplastics and thermosetting plastics. Thermosetting plastics, such as bakelite powder, are permanently formed by pressing under heating and pressure. Bakelite moulds are periodically subjected to pressure and continuously heated at 150-200 degrees. Thermoplastics, such as polyvinyl chloride, are usually formed by injection moulding. Plastics are

In the plastic mold manufacturing industry, in order to facilitate demolding, improve efficiency, prolong the life of plastic molds, make the surface of products smooth, qualified size and reduce waste products, demoulding agents are usually needed. The release agent can be roughly divided into internal release agent and external release agent. The internal release agent
