What should be paid attention to when choosing injection molding tooling? At present, plastic injection molding production is mainly divided into two types. One is a conventional plastic mold. Under normal circumstances, this kind of mold has a life span of 100,000 to 200,000 molds. Mainly used for small batch injection processing, usually referring to 100-2000 pieces per processing. There is another kind of mold that is used in mass production. This kind of mold has a long life, basically it won't come down after being hung up on the injection molding machine. Production is non-stop all day long, which requires high mold life. This kind of mold material is more than double the processing technology, material and processing cost after heat treatment, and the production capacity exceeds one million times.

The surface gloss and accuracy of injection molded plastics with good wear resistance are directly related to the wear resistance of the injection mold cavity surface, especially some plastics add glass fibers, inorganic fillers and pigments, and they flow with the plastic melt and flow at high speeds. Cavity. The cavity surface friction, if the material is not worn, it will wear out quickly, and the quality of the plastic will be lost.

The mold material must have good dimensional stability for injection molding, and it is best to select an appropriate tool steel for heat treatment.

The mold must be sprayed with rust inhibitor after production. Reduce the possibility of rust in the cavity and core. Therefore, the mold material must be corrosion resistant.
