What is a plastic mold? Many people do not know, in fact, plastic mold is a combination of mold can be used for compression molding, extrusion, injection, blow molding and low foam molding. The coordinated changes of the mold convex and concave molds and the auxiliary forming system can process a series of plastic parts of different shapes and sizes. Plastic molds are the mother of industry, and now the release of new products will involve plastics. Below Ke Shimei for everyone to talk about what is a plastic mold!



According to Xiaobian, plastic mold is a tool for producing plastic products, and it is also a tool for giving complete structure and precise size of plastic products. Injection molding is a processing method used in mass production of complex parts of certain shapes. Specifically, the plastic melted by the heat is injected into the cavity by the high pressure of the injection molding machine, and after solidification by cooling, a molded article is obtained.


Although the structure of the mold may vary depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is uniform. The mold is mainly composed of a gating system, a temperature control system, a molded part and a structural part. The gating system and the molded part are in direct contact with the plastic and vary with the plastic and the product. It is the most complicated and most varied part of the mold, and requires the highest degree of smoothness and precision.


Plastic molds are classified into thermosetting plastic molds and thermoplastic plastic molds according to their molding characteristics; they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot stamping molds (compression molding molds), injection molds, etc. according to the molding process. The hot stamping die can be divided into three types: overflow type, semi-overflow type and non-overflow type. The injection mold can be divided into two types: cold runner mold and hot runner mold; Can be divided into mobile, fixed two.


This is the introduction of plastic molds. Now everyone knows what plastic molds are? Keshimei is a professional plastic two-color mold manufacturer. If you have related business or needs, you can come to Keshimei!
