Injection molding is an injection and molding method, also known as injection molding.

Detailed process:

The first step is the mold clamping process: the pressure oil in the clamping cylinder pushes the action of the clamping mechanism, and the movable template moves to close the mold.

The second step of the injection device: after the injection process mold is locked by the clamping force, the injection device enters the working condition to make the nozzle and the mold fit.

The third step of the pressure holding process: the molten material is filled in the cavity until the filling is completed, the screw is required to maintain a certain pressure on the molten material to prevent the melt in the mold from flowing back.

The fourth step of cooling and pre-molding process: once the gate is sealed, the pressure-preserving process is cancelled, and the product is naturally cooled and shaped in the mold; at the same time, the Dekuma injection molding machine drives the pre-plastic oil motor to rotate the screw, which will be granular from the hopper. The plastic is transported forward for plasticization.

The fifth step is injection device retreat, mold opening and plastic product ejection process: After the pre-plastic metering and anti-duction process is finished, in order to prevent the nozzle from forming cold material due to contact with the cold mold for a long time, it is usually necessary to evacuate the nozzle from the mold. That is, the injection device is returned to the working condition.

Injection molding, also known as injection molding, is an injection-molding molding method. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, variety of colors, shapes from simple to complex, the size can be from large to small, and the size of the product is accurate, the product is easy to be replaced, and the shape can be complicated. Parts, injection molding is suitable for molding processing such as mass production and complex shapes.

At a certain temperature, a completely molten plastic material is stirred by a screw, and a method of obtaining a molded article is obtained by injecting a high-pressure into a cavity and cooling and solidifying. This method is suitable for mass production of complex shapes and is one of the important processing methods.
