A new physical foaming process and a significant enhancement of the MuCell process attract attention at the show. Foam molding is seeing increased attention in the marketplace and is on display at several injection and blow molding booths in Orlando. New developments include the U.S. debut of the Plastinum foam injection molding process from Linde LLC (S24207), a leading supplier of industrial gases. This process involves impregnating plastic pellets with carbon dioxide gas in a pressurized chamber, or autoclave. Gas-loaded pellets can then be conveyed to the hopper(s) of one or more molding machines. The hopper is not sealed or under pressure, since gas will remain in the pellets at ambient conditions for 4-6 hr. No modifications to the injection press are required, except for use of a shutoff nozzle. More new technology for physical foam molding is being introduced at NPE by Trexel (W551), whose new dosing equipment reportedly allows thin-wall molders to lightweight products to a level never before possible. The new MuCell P-Series delivers nitrogen under pressure as a supercritical fluid, and is able to do so at ultra-fast cycle times not previously possible with Trexel’s T-S...
