The
New Car injection molding process is to flow the plastic melt into a closed cavity under high pressure, and after heating and condensation, obtain a plastic product with the same shape as the cavity. Today I will introduce you to the basic principles of plastic injection molding.
Plastic plasticization: In the
Fuel Car injection molding process, the solid plastic moves upward through the rotating screw, moves at intervals along the groove direction, and is heated by the heating, compaction, stress and mixing of the thread. It is transformed into a delicious fluid plastic melt with symmetrical density, viscosity and composition, and a stable source.
New Car injection molding process: The plasticized plastic melt is stored in the storage area of the barrel, and the screw rotates the shaft during the injection process. Under the action of the screw injection pressure, the plastic melt passes through the barrel at a specific speed. The front-stage nozzle, the pouring system of the molding mold, etc. flow into the mold cavity.
Cooling and solidification process: The plastic melt flowing into the mold cavity overflows the mold cavity, eliminating various movement resistances. The plastic melt added to the cavity is subjected to a very large pressure from the cavity, thereby driving the movement of the plastic melt. The tendency of returning to the barrel is that the plastic melt is heated and stretched due to the cooling effect of the cavity.
At this time, the screw is taken again to obtain pressure, so that the plastic melt does not increase the entry into the cavity, so that it does not migrate, and the cavity is properly filled by the plastic melt. The main body increases the shrinkage space in the cavity until the plastic melt is gradually heated and solidified into a product.
