If the product can meet the same requirements for use, the use of gas-assisted injection molding can greatly save plastic raw materials, and its saving rate can be as high as 50%. On the one hand, the reduction in the amount of plastic raw materials brings about a reduction in the time of each cycle of the entire molding cycle; on the other hand, the introduction of high-pressure gas inside the parts has greatly improved the shrinkage deformation of the parts, so the injection pressure holding time, Injection pressure can be greatly reduced pressure. Gas-assisted injection reduces the working pressure of the injector injection system and the clamping system, which in turn reduces energy consumption during production and increases the service life of injection molding machines and molds. At the same time, due to the reduction of the pressure of the mold, the corresponding material of the mold can be selected to be relatively inexpensive. The parts processed by gas assist technology are hollow structures, which will not only reduce the mechanical properties of the parts, but will also increase them, and will also be of great benefit to the dimensional stability of the parts.

The process of gas-assisted injection is slightly more complex than ordinary injection molding. The control of parts, molds, and processes is basically performed using computer-aided simulation. The requirements for injection molding machine systems and equipment are relatively simple. At present, more than 80% of them are in use. The injection molding machine can be fitted with a gas-assisted injection molding system after a simple modification. There are no special requirements for raw materials. General thermoplastics and engineering plastics are suitable for gas-assisted injection molding.
