the extrusion and injection technology of melt pump
Melt pump extrusion:
Melt pump Extrusion molding is also called extruding molding in the plastic processing, in the non-rubber extruder processing by hydraulic press pressure in the mold itself extruded. It is a kind of processing method that the material is heated and plasticized by the extruder barrel and screw, which is pushed forward by the screw, and is made into various cross section products or semi-products continuously through the head of the machine.
Melt pump injection molding:
Using plastic heating to a certain temperature, the Melt pump injection molding machine can melt into liquid properties, the molten liquid with high pressure injected into the closed cavity, after cooling and shaping, after opening the mould to get the required plastic products.
