The use of carbon dioxide (CO2) represents a breakthrough in gas-assist injection molding (GAIM), with significantly reduced cycle times.
The Enhanced GAIM (eGAIM) process uses carbon dioxide (CO2) to greatly improve Gas-Assist Injection Molding (GAIM). Developed and patented by Linde, eGAIM represents a significant breakthrough in injection molding technology. Linde found that by replacing liquid nitrogen (N2) with cryogenic CO2 as the gas assist, injection molders could greatly reduce cycle times. In fact, cooling cycles can often be reduced by more than 50% compared to cycles using N2, and overall cycles can often be reduced 20% - 50%.
“The high efficiency of carbon dioxide, including low investment costs, easy installation and convincing results, make it very attractive for injection molding for both new molds and for retrofitting existing molds,” says Jim Stanley, Linde Program Manager for the North American plastics industry.
5 Major Benefits of eGAIM
The cooling effect of high-pressure CO2 is comparable to that of water in Water Assist Injection Molding (WAIM), without many of the difficulties inherent in WAIM. The high-pressure injection of the inert gas contributes to rapid and complete mold filling and better surface characteristics for rapid mold release and repeatable quality.
