What is the difference between plastic molds and injection molds

Plastic mold is a combination of plastic molds used for compression molding, extrusion molding, injection molding, blow molding, and low foam molding. It mainly includes a concave mold with a variable cavity composed of a concave mold combination substrate, a concave mold component, and a concave mold combination clamp plate, and a convex mold with a variable core composed of a convex mold combination substrate, a convex mold component, a convex mold combination clamp plate, a cavity cutting component, and a side cutting combination plate. Coordinate changes in mold convex, concave, and auxiliary forming systems. Can process series of plastic parts of different shapes and sizes.

Injection mold is a type of plastic mold, which includes injection mold, extrusion mold, and suction mold. Like the production of injection molds, the method of injecting plastic materials is used to open the mold and form the product. Injection molding can also be understood as a mold with an empty center and a fixed small hole on the body, through which plastic material is injected into it. Through high-temperature heating, molding, opening the mold, and obtaining the product.

There are five main systems for plastic molds, namely: pouring system, temperature control system, forming parts system, exhaust system, guide system, and ejection system. The pouring system and molding parts are the parts that come into direct contact with plastic and change with plastic and products. They are complex and highly variable parts in plastic molds that require processing smoothness and accuracy.
