Injection molding, also known as injection molding, is a molding method of injection and molding

 

The advantages of injection molding method are fast production speed, high efficiency, automatic operation, variety of designs and colors, shapes can be from simple to complex, size can be from large to small, and the product size is accurate, the product is easy to replace, can form complex shape parts, injection molding is suitable for mass production and complex shape products and other molding processing fields.

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

The injection molding process can be roughly divided into the following six stages:

Mold closing, glue injection, pressure retention, cooling, mold opening, product removal.

The above process is repeated, can batch periodic production of products. The molding of thermosetting plastics and rubber also includes the same process, but the temperature of the barrel is lower than that of thermoplastic plastics, and the injection pressure is higher. The mold is heated, and the material is injected into the mold to be cured or vulcanized, and then the film is taken off while hot.

The current trend of processing technology is developing towards the direction of high technology, these technologies include: micro injection molding, high filling composite injection molding, water injection molding, mixed use of various special injection molding technology, foam injection molding, mold technology, simulation technology, etc.
