The difference between low pressure injection molding machine and ordinary injection molding machine:
1. Low-pressure injection molding uses different materials from traditional injection molding machines. The low-pressure injection molding material used in low-pressure injection molding has a very low viscosity and does not need to be extruded by a screw, as long as it is heated and melted by a rubber cylinder, injected through a gear pump, and then cooled to form.
2. The low pressure injection molding machine does not have a screw device, and the glue is injected through a gear pump, a hose and a glue gun. Low-pressure injection molding is pre-heated injection molding of hot melt adhesive. The low-pressure injection molding equipment uses three-stage heating to melt the material into a liquid in advance. Through the actual product demand and temperature adjustment, the CPS can be changed to the most suitable product's fluidity, so these are not reachable by the high-pressure machine. Ordinary injection molding equipment (traditional injection molding) adjust the pressure to the lowest, because the viscosity of the material is high, there may be insufficient injection of glue, that is, lack of glue. In addition, low-pressure injection molded materials have good bonding properties, which are unmatched by traditional engineering plastics.
