abstract = "A novel Supercritical fluid pellet Injection Molding Foaming (SIFT) technology for producing injection molded parts with a foamed structure has been developed. The idea is to pre-load an atmospheric gas, such as carbon dioxide (C02) or nitrogen (N2), into the plastic pellets to act as a physical blowing agent. Processing those gas- laden and ready-to-foam pellets using regular injection molding machines lowers equipment costs without sacrificing the production rate, thus making it a viable and attractive candidate for the mass production of foamed injection molded parts. This process is akin to employing a chemical blowing agent (CBA) without the typical concerns of chemical residual. The shelf life of the gas- laden pellets is an important factor in this process because the effective gas content may vary with time due to gas desorption, which could lead to variation in part quality. In this paper, research results on (1) comparison of shelf life using C02 and N2 as the blowing agent, (2) shelf life of C02-laden pellets, and (3) evaluation of effective gas content in the C02-laden pellets are presented.",
