According to different molding methods, plastic processing mold types corresponding to different process requirements can be divided, mainly including injection molding mold, extrusion molding mold, suction molding mold, high foaming polystyrene molding mold, etc.

Plastic molds are tools used in the plastic processing industry to complement plastic molding machines, endowing plastic products with complete configurations and precise dimensions. Due to the wide variety of plastic varieties and processing methods, as well as the complex and simple structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

Working conditions of plastic molds

Due to the development of the plastic and plastic molding industry, the quality requirements for plastic molds are becoming increasingly high. Therefore, the issue of plastic mold failure and its influencing factors has become an important research topic. The main working parts of plastic molds are formed parts, such as convex molds and concave molds, which form the cavity of the plastic mold to form various surfaces of plastic parts and directly come into contact with the plastic, enduring pressure, temperature, friction, and corrosion.

The various tools and products we use in our daily production and daily life, ranging from the base of machine tools and the outer shell of the machine body to a small screw, button, and the outer shell of various household appliances, are all closely related to molds. The shape of the mold determines the appearance of these products, and the processing quality and accuracy of the mold also determine the quality of these products.

Due to the different materials, appearances, specifications, and uses of various products, molds are divided into non plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds.
