The mold material must have good dimensional stability for injection molding, and it is best to select appropriate tool steel for heat treatment. Another kind of mold is a mold for mass production. Under normal circumstances, this kind of mold has a life of 100,000 to 200,000 processing of plastic products molds. Cavity. 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. Cavity surface friction, if the material is not worn, it will wear quickly and the quality of the plastic will be lost.

The surface gloss and accuracy of injection molded plastics with good wear resistance are directly related to the wear resistance of the surface of the injection mold cavity, especially some plastics add glass fiber, inorganic fillers and pigments, and they flow with the plastic melt and flow at high speed.

The mold must be sprayed with rust inhibitor after production. Production is non-stop all day long, which requires high mold life. Reduce the possibility of rust in the cavity and core. Mainly used for small batch injection processing, usually referring to 100-2000 pieces per processing..

Therefore, the mold material must be corrosion resistant.The classification of plastic molds and what should be paid attention to when choosing plastic molds? There are two main types of plastic mold injection production. One is a conventional plastic mold. This kind of mold has a long life, basically it won't come down after being hung on the injection molding machine
