The gas-assisted injection molding process cycle is:

Injection period

Quantitative plasticized plastic fills the mold cavity. The required amount of plastic is to be found through experiments to ensure that during nitrogen filling, the gas will not break through the surface of the finished product and there will be an ideal volume of nitrogen flushed.

2. Inflatable period

The gas can be injected at different times during or after the injection period. The gas injection pressure must be greater than the injection pressure in order to reach the product into a hollow state.

3. Gas pressure period

When the interior of the finished product is filled with gas, the pressure of the gas acting on the hollow part of the finished product becomes the holding pressure, which can greatly reduce the shrinkage and deformation rate of the finished product.

4. Demoulding period

As the cooling cycle is completed, the gas pressure of the gas-assisted mold is reduced to atmospheric pressure and the finished product is ejected from the mold cavity.
