What is an injection mold?
The mold used for injection molding is called an injection molding mold.
The plastic is heated and melted in the heating cylinder of the injection molding machine, and then driven by the injection molding machine screw or piston, it enters the mold cavity through the nozzle and mold pouring system, and finally hardens and sets in the cavity. process.
Injection molding molds are mainly used for the molding of thermoplastic plastic products, but in recent years, they have also been increasingly used for the molding of thermosetting plastics.
At present, injection molding molds account for a large proportion in the molding of plastic products, so about half of the production of plastic molding molds are injection molds.
What is an extrusion mold?
The mold used for plastic extrusion is called an extrusion mold.
The extrusion molding die is also called the machine head. The plastic in a viscous state is passed through a die with a specific cross-sectional shape under high temperature and high pressure, and then cooled and shaped at a lower temperature. The molding method used to produce a continuous profile with a desired cross-sectional shape is called extrusion molding.
