1. SEALED INJECTION GAS It is a method to inject gas directly into the mold cavity to make the plastic product hollow. It does not need to use a live valve, but simply installs gas nozzles through simple mold processing.

Gas pressure in the mold. On the same mold, one or more gas injection sites can be used.

2. IN-GAS NOZZLE: It is a special injection nozzle installed on the injection molding machine.

3. EXTERNAL GAS MOLDING: This is a patented technology of British CINPRES GAS INJECTION LTD. It is suitable for the production of mobile phones, electronic organizers and small household appliances.

Features Edit the advantages of external gas assisted injection molding:

1) Exclude finished product sag.

2), to reduce warping deformation. In the traditional injection molding process, pressure retention can avoid defects such as sag and shrinkage of the finished product, but at the same time it increases the internal stress of the finished product and causes warpage. However, external gas injection molding has cited gas as a

External pressure is applied to eliminate dents and shrinkage. Therefore, the internal stress of the finished product does not increase, and the warpage phenomenon can be improved.
