We all know that plastic injection molds are all about a single product. Different plastic products, the plastic injection molds it develops will be different. Sometimes even the same plastic products use different requirements, so the plastic injection molds we process will be different. From the perspective of plastic materials, plastics have the following effects on the injection mold.

On the one hand, different plastics will have different shrinkage. This is when we consider processing plastic injection molds, we must pay attention to the shrinkage rate of plastic injection molds. Before we open the plastic injection mold, we must determine the shrinkage of the mold, otherwise it will easily cause the mold to be scrapped. Especially large plastic molds.

On the other hand, plastic characteristics of the plastic mold steel requirements. When we are processing plastic injection molds, we must first understand the types of plastics when choosing mold steel. For example, we often use nylon plastic, which is corrosive. When we choose mold steel, we should consider stainless steel mold steel. If we use high-transparency PC plastic, we have to choose high-bending mold steel, such as 2738.
