When the production is over or the quality of injection molding fails, the injection molding machine needs to be shut down temporarily or for a long time. How to do the shutdown work is not only related to the quality of the next molding and the loss of raw materials, but also affects the service life of the screw and barrel.

Plastic molds are tools used with plastic molding machines in the plastic processing industry, and can provide complete structural configurations and precise dimensions for plastic products. According to different molding methods, plastic molds can be divided into the following three types. 1.Injection mold Injection molds are often used to produce thermoplastic parts, and the corresponding processing equipment is injection molding machines.

Mold material selection is a very important link in the entire mold making process. Mold material selection needs to meet three principles: The mold meets the work requirements of wear resistance, strength and toughness; The mold meets the process requirements; At the same time, the mold should meet the requirements of economic applicability. The mold meets the requirements of working conditions
