Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are that the production speed is fast, the efficiency is high, the operation can be automated, there are many varieties of colors, the shape can be 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 replace, and it can be formed into complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields.

At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of complex-shaped parts, and is one of the important processing methods.

Nowadays, the trend of processing technology is developing in the direction of high-tech. These technologies include: micro-injection, high-fill composite injection, water-assisted injection, mixed use of various special injection molding processes, foam injection, mold technology, simulation technology, etc.
