Our Gas-Assisted Injection Molding Services
Gas-Assisted Injection Molding (GAIM) is an advanced technique that injects inert gas into molten plastic to create light-weight, high-strength parts with reduced material usage and minimal warpage. Our GAIM technology classifies production into wall-thickness optimization and core reinforcement, ensuring precise dimensional control and superior surface quality. Integrated simulation and strict process control enable efficient, cost-effective mass production of complex, hollow components from a wide range of polymers.
In Direct GAIM, high-pressure inert gas is injected directly into molten plastic, forming hollow channels to reduce weight.
Indirect GAIM introduces gas via dedicated channels beside the melt, ensuring controlled cavity formation and smooth surfaces.
Sequential GAIM uses multiple gas injections to optimize internal structure and balance wall thickness for strength.
Co-injection GAIM simultaneously injects plastic and gas, integrating hollow sections for uniform material distribution and weight reduction.
