After a certain time, it hardens and takes the desired shape. Pressure molding differs from compression molding in that it has a separate charging chamber. The mold is closed before molding, the plastic in the charging chamber is preheated to a viscous state and is extruded under pressure into the mold cavity, where it hardens and takes the shape.
The compression mold mainly consists of a cavity, a charging chamber, a guide mechanism, a starting part, a heating system and so on. Compression molds are widely used to encapsulate electrical components. The materials used in the manufacture of compression molds are basically the same as those used in injection molds.
Plastic extrusion mold is used to form continuous cayman islands number data plastic products of certain shapes, also known as extruder die, widely used in the production of pipes, rods, monofilaments, sheets, films, wire and cable coatings, profiles and other products.
The equipment corresponding to plastic extrusion molds is a plastic extruder. The principle is that the solid plastic under the conditions of heat and rotational pressure of the extruder screw is melted, plasticized, and formed into continuous plastic products through a certain shape of the mold opening with a cross section and shape corresponding to the shape of the mold opening.
The materials for making plastic extrusion molds mainly include carbon structural steel, tool alloys, etc. Some extrusion molds that need wear-resistant parts can also be equipped with diamonds and other wear-resistant materials. The extrusion process is generally only suitable for the production of thermoplastic products, and its structure and the structure of injection molds and compression molds have obvious differences.
