[0002] Common discharging molds include extrusion molds for plastic processing. Plastic extrusion molds are a type of molding mold, but their discharging method is achieved through extrusion. They are widely used in aluminum special-shaped structures and are also used in plastic parts. At the front end of the extruder, they are used to make pipes or special-shaped materials. In short, the mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts.
