Gas Assisted Injection Molding

Gas Assisted Injection Molding The gas-assisted injection molding system uses an inert gas (usually nitrogen) directly injected into the plasticized plastic in the cavity through the sectional pressure control system to expand the interior of the plastic part to create a hollow shape, but still keep the surface of the product intact. Gas-assisted injection molding…
