Rapid Injection Molding Process

The rapid injection molding process includes the following steps:

1. Feeding: As injection molding is an intermittent process, quantitative feeding is required to ensure stable operation, uniform plastic plasticization, and ultimately obtain high-quality plastic parts.

2. Plasticization: The formed material is heated, compacted, and mixed inside the barrel of the injection machine, transforming from a loose powder or granular solid to a continuous homogenized melt.

3. Injection: The process in which a plunger or screw starts from the measuring position inside the barrel and applies high pressure through the injection cylinder and piston to quickly feed the plasticized plastic melt into the closed mold cavity through the nozzle at the front end of the barrel and the pouring system in the mold. Injection can be further divided into three stages: flow molding, pressure holding and contraction, and backflow.

4. Cooling: When the plastic in the pouring system has frozen, continuing to maintain pressure is no longer necessary. Therefore, the plunger or screw can be returned to remove the pressure of the plastic melt in the barrel, and new material can be added. At the same time, cooling media such as cooling water, oil, or air can be introduced into the mold to further cool the mold. In fact, the cooling process starts from the injection of plastic melt into the mold cavity, which includes the period from mold filling, pressure holding to before demolding.

5. Demoulding: After curing is completed, open the mold and take out the finished product.
