The gas-assisted process is a relatively complicated process. In general, the product is filled first, then the high-pressure inert gas is blown, the raw material in a semi-molten state is blown out, and the gas is used instead of the injection molding machine to obtain the product. Become a gas-assisted molding.

Gas-assisted molding can also be solved by unconventional methods, such as injecting nitrogen into the mold at 70%-80% immediately, and using nitrogen-assisted molding for the filled position. This process is also a conventional process and can be used if necessary.

The number of modules in the gas-assisted mold is mostly 1*1. The number of mold cavities will cause the rubber or the intake air to be unstable. This process is difficult to adjust. When it is produced normally, it will produce a high scrap rate. Therefore, it is generally recommended. Modular cavity structure. If you design a 1+1 mold structure, you need two separate air inlets for the two-point needle valve. Two gas-assisted controllers are required, which will stabilize the product.
