[0002] Injection molding machine, also known as injection molding machine or injection machine, can heat plastic, apply high pressure to molten plastic, make it eject and fill the mold cavity. It is a main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. The working principle of the injection molding machine is similar to that of a syringe for injections. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (i.e. viscous flow state) plastic into the closed mold cavity, and obtains the product after solidification and shaping. The storage device is a device used to store plastic raw materials in the injection molding machine.
