In general, injection molding is a method of manufacturing an injection molded product having a specific shape by injecting a predetermined plastic molten resin into an injection mold unit incorporated with each other, and manufacturing industrial parts using plastic materials. It is one of the molding methods used in various ways.

The mold apparatus used in such an injection molding operation is generally composed of a fixed mold and a movable mold, and has a structure in which the movable mold is combined with or separated from the fixed mold by a pressing force of a transfer cylinder rod.

Therefore, in the injection molding operation, the movable mold and the fixed mold facing each other are merged into one, and the molten resin is forcibly injected into the mold while the clamping force of the molds is maintained, so that the molten resin is mixed with the sprue and the gate. The (gate) is sequentially moved and then filled in a cavity, which is a molding space, thereby manufacturing an injection molded product corresponding to the shape of the cavity.
