What is the meaning of injection molding machine before melting and pumping and after melting? What's the function of 10?

Answer:

Before the pumping molten refers to the pumping action in the melt before the start, to remove the injection pressure in the cylinder head, the buildup of pressure; pumping molten refers to the pumping action in the melt after the end to relieved some of the pressure generated by the melt.The pumping action is not necessary, generally set according to the nature of raw materials, no salivation phenomenon is not used.
The glue is used to prevent the glue from coming out after it is stored,
Injection molding machine melting process is through the rotation of the screw, the material inside the bucket through the screw to the front end of the screw rod propulsion, screw rotation is not only itself active back, when the barrel material is pushed to the front end of the screw in the front of the barrel, the pressure will be more and more, will be forced to retreat when the screw, screw back the set position, the screw stops rotating, melt end. In order to prevent the pressure in the barrel is too large but the glue flows out from the nozzle, usually used to pumping (also called loosening, cable, shot back down), the active screw back a certain distance (usually a few mm) to remove part of the pressure.
