We have rich experience in making plastic gas-assisted chair mould and we have our own equipment for Gas-assisted  chair mould injection line and plastic molding machines.

Below is the Theory of the Gas - Assisted Injection Molding.

1. After the mold is clamped, the plastic is filled the mold cavity area.

2. After the set time interval, the first stage is the injection gas.

3. The second stage relapses the plastic to compensate for the plastic shrinkage caused by cooling

4. There will be a uniform pressure in the plastic

5. The mold will disappear before the mold is opened

6. When the nozzle valve is closed or the gate is solidified, the plastic will be filled again
