What is a plastic mold?

‌‌Plastic molds are molds used for plastic molding. According to the molding principle, they can be divided into injection molds, compression molds, and transfer molds. ‌‌

Plastic molds are indispensable tools in the plastic processing industry, which give plastic products complete configurations and precise dimensions. Due to the diversity of plastic varieties and processing methods, as well as the complexity of plastic molding machines and plastic product structures, the types and structures of plastic molds are also diverse. These molds are mainly used in automobiles, home appliances, electronic communications, daily necessities and other fields, reflecting the importance and wide application of plastic molds in industrial production.

Specifically, the types of plastic molds include but are not limited to injection molds, compression molds, transfer molds, etc. Injection molds are mainly used to inject molten plastic into molds, and obtain products of the desired shape after cooling; compression molds are used to heat and pressurize plastic particles; transfer molds are suitable for the molding process of certain special plastics. The structure of these molds is usually composed of molding parts, pouring systems, guide parts, temperature control systems, etc., and the manufacturing materials are mostly plastic mold steel modules, such as carbon structural steel, carbon tool steel, alloy tool steel, etc.

In addition, plastic molds are widely used, from daily necessities to complex mechanical parts, electrical components, etc., all of which are produced through the injection molding process. This process is not only applicable to thermoplastics, but also to the molding of certain thermosetting plastics, demonstrating the key role of plastic molds in modern production.
