For at least a decade, gas-assisted injection molding (GAIM) processes have been used successfully to form hollow, tubular products, such as appliance handles, using fiber-reinforced thermoplastics.

Polyphenylene sulfide (PPS) resin is being employed in a gas-assisted injection molding process to reduce weight and costs of tubular cooling system parts for automotive engines. The Fortron material ...

Known for producing hollow parts, gas-assist techniques can overcome many of the limitations of conventional injection molding. The first patents for gasassist injection molding came in the early ...

Gas-assist can cut resin costs and eliminate weld lines and sink marks. Because it's a low-pressure process, it avoids molded-in stresses, and allows processors to use smaller-tonnage machines.

• Gas-assist injection molding can cut weight, cycle time, and press requirements. • Experienced molders can help OEMs develop tooling, refine process parameters, and choose materials for high-gloss ...

Robert Joyce says gas-assisted molding is the best way to solve tough challenges of injection molding wood-plastic composite balluster spindles - the long pieces that run down vertically to support a ...

In an attempt to bring a new level of consistency to gas-assist molding, Ferromatik Milacron has developed Airpress III, a patented system that modifies resin injection and delays the timing for the ...
