What is the difference between a plastic extruder and an injection molding machine?

1. An extruder, specifically a screw extruder, relies on the pressure and shear forces generated by the rotating screw to thoroughly plasticize and uniformly mix the material, which is then shaped through the die at the die head. 2. An injection molding machine, also known as an injection molding press or injector, is the primary equipment used to produce various plastic products by shaping thermoplastic or thermosetting plastics using molds. It comes in vertical, horizontal, and all‑electric configurations. The machine heats the plastic and applies high pressure to force the molten material into the mold cavity, thereby forming the desired part. Hebei Shuangda Rubber & Plastics Machinery Co., Ltd. is a company engaged in the research, development, and manufacturing of complete sets of extrusion machinery for rubber, silicone, and plastics.
