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.
The injection molding process can be roughly divided into the following six steps.
