Injection molding, also known as injection molding, is a method of injection molding. Injection molding method has the advantage of production speed, high efficiency, can realize automation operation, breed of design and color is much, can shape by Jane to numerous, can from big to small size, and precise in dimension and product upgrading, can into complex shape parts, injection molding is suitable for mass production with complex shape product and processing field.

At a certain temperature, the plastic material is stirred by screw and injected into the mold cavity with high pressure. After cooling and curing, the molding material is obtained. This method is suitable for mass production of complex parts and is one of the important machining methods.
