Detailed process of injection molding and its work

Injection molding is a molding method of injection and molding, also known as injection molding.
Detailed process:
First, the mold clamping process: the pressure oil in the mold clamping cylinder pushes the mold locking mechanism to act, and the movable template moves to close the mold.
Step 2 injection device: after the mold is locked with the mold locking force during the injection process, the injection device operates to make the nozzle and the mold fit.
The third step is the pressure maintaining process: during the process of filling the mold cavity, the screw is required to keep a certain pressure on the molten material until it is filled, so as to prevent the molten material in the mold from flowing back.
Step 4 cooling and pre molding process: once the gate is sealed, the pressure maintaining process is canceled, and the products are naturally cooled and shaped in the mold; At the same time, the DEKUMA injection molding machine drives the pre molding oil motor to rotate the screw, and the granular plastic from the hopper is transported forward for plasticization.
Step 5 injection device withdrawal, mold opening and plastic product ejection process: after the completion of pre molding metering and delay prevention process, in order to prevent the nozzle from forming cold material due to long-time contact with the cold mold, it is usually necessary to withdraw the nozzle from the mold, i.e. enter the injection device withdrawal condition.
Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, multiple designs and varieties, simple to complex shapes, large to small sizes, accurate product sizes, easy updating of products, and complex shape products. Injection molding is suitable for mass production and molding processing fields such as complex shape products.
At a certain temperature, the fully melted plastic material is stirred by the screw, injected into the mold cavity with high pressure, and then cooled and solidified to obtain the molded product. This method is suitable for batch production of complex parts and is one of the important processing methods.
