Injection molding process to screw injection machine as an example of the first clamping and clamping, through the clamping mechanism to make the mold to close quickly with low pressure, when the moving template and the fixed template is close to, the moving template will move forward with low pressure and low speed.   

When confirming that there is no foreign matter in the mold, the mold is closed and locked with high pressure. Then the injection system is moved forward and injection and pressure holding. After the mold is locked, the injection system moves forward to make the nozzle and the mold fit. The screw moves forward rapidly under the action of the piston of the injection cylinder to inject the molten material at the front end of the barrel into the mold cavity at high pressure and speed.   

Injection molding: refers to a certain shape of the model, through the pressure will melt state of colloidal injection cavity and forming, process principle is: the solid plastic melting according to certain melting point, through the pressure of the injection machine, injection mould with a certain speed, die through channel cooling cavity will get plastic solidification and design the same product.
