In recent years, gas-assisted injection molding technology has been used in the production of many plastic parts, such as televisions or audio enclosures, automotive plastic products, furniture, kitchen utensils and daily necessities, various types of plastic boxes and toys and so on. Compared with ordinary injection molding, gas-assisted injection molding technology has many unparalleled advantages, it can not only reduce the manufacturing cost of plastic products, but also can improve some of its properties.

In the case that the parts can meet the same requirements, the use of gas-assisted injection can greatly save the 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 carried out 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.

Due to the superiority of gas-assisted injection molding technology in many aspects and its wide range of applications, there are no excessive requirements for equipment and raw materials. Therefore, in the future development, the application of this technology in the injection molding industry will surely become more and more. widely.
