Figure 1. Pressurized nitrogen gas is injected into a melt to penetrate the part via a network of thicker cross-sectioned gas channels (click to enlarge). Gas-assist injection molding was developed ...

Fear oflawsuits has kept many design engineers from using the gas-assist process forinjection molded parts. Gas-assist molding was a way to reduce the weight ofthick parts, improve the surface finish ...

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 ...

This gas-assisted injection molder is equipped with a cryogenic heat exchanger that may increase productivity by as much as 40%. A gas-assisted injection molding (GAIM) process developed by scientists ...
