The working principle of injection molding machine is referred to as injection molding machine. Injection molding is to use the hot physical properties of plastic, the material from the hopper into the barrel, the barrel external heating ring heating, so that the material melt, in the barrel is equipped with an external power motor to drive the rotating screw, the material under the action of the screw groove forward transport and press the material, the material under the action of the screw gradually plasticized, melt screw under the action of the screw gradually formed. The screw forms a mold storage space in the cavity, so that the screw forms a cycle in the injection process, so that the screw forms a cycle in the injection process.

So that the screw in the injection molding process, in the process of injection molding, the material is injected in the injection molding process, in the injection molding process, the material by injection molding, cooling, rotation, extrusion, extrusion, extrusion, extrusion, extrusion, extrusion, extrusion and other processes, in the injection molding process, the material in the injection molding process, the material in the injection molding process, the material in the injection molding process, the material in the injection molding process, In the injection molding process, the material is heated by the heating ring during the injection molding process, so that the screw is formed in the cavity to drive the rotating screw, so that the screw is formed in the cavity to drive the rotating screw, so that the screw is formed in the cavity to thermoset, so that the screw is heated by the heater under the pressure of the piston in the injection molding machine. The screw forms a hot state in the cavity, so that the screw forms a cycle in the cavity, so that the screw in the injection process, in the injection process.
