Plastic extrusion dies are an important process equipment in modern industry and an indispensable part of the production of many industrial products. After joining the WTO, China's ability to attract foreign investment has increased year by year, becoming a world product manufacturing plant, importing more and more industrial molds.
The type of mold is usually classified according to different processing objects and processes. From an industrial point of view, they mainly include plastic molds, rubber molds, metal cold stamping tools, metal cold extrusion molds and hot extrusion molds, metal tensile molds, powder metallurgy molds, metal die-casting molds, metal precision casting molds, and glass. Mold, glass fiber reinforced plastic mold, etc.
The most common molding methods for plastics are usually divided into melt molding and solid phase molding. Melt molding is a method of heating a plastic to a temperature above the melting point and melting it. The molding process belonging to the molding method mainly includes injection molding, compression molding (shrinking) molding, extrusion molding, and the like. Solid phase molding refers to a molding process in which the plastic is maintained in a solid state below the melting temperature, such as vacuum molding, compressed air molding, and blow molding in the production of some plastic packaging containers. In addition, there are liquid molding methods such as casting molding, slush molding, and dip molding.
According to the above different molding methods, the types of plastic processing molds corresponding to different process requirements can be divided, mainly including injection molds, extrusion molding molds, compression molding molds, blow molds, blister molding molds, and high expansion polystyrene molding molds.
