We all know that plastic molds are all about a single product, different plastic products, it will develop plastic mold will be different, sometimes even the same plastic products, use different requirements, so that we process the plastic mold will be different. Considering only plastic materials, it will have the following effects on the mold.

   On the one hand, different plastics caps and closures will have different shrinkage, which is when we consider the processing of plastic molds, we must pay attention to the plastic mold shrinkage problems. Before we open the plastic mold, we must determine the shrinkage of the mold, otherwise it will easily cause the mold to be scrapped,eEspecially large plastic molds.

   On the other hand, plastic properties on the plastic mold steel requirements. When we are processing plastic molds, we must first understand the types of plastics when we choose mold steels, such as we often use nylon plastic, which is corrosive, when we choose mold steel, we must consider using stainless steel mold steel, if we use high-transparent PC plastic, we must choose the high polishing performance of the mold steel, such as 2738 and other materials.
