Injection molding: Microcellular foaming for smaller presses

The new version of this firm?s MuCell process for microcellular foaming enables processors to integrate the MuCell process on injection molding machines with screw sizes of 40 mm or less. Recently the firm also introduced a system designed for use with molding of long-fiber-reinforced compounds.It can be integrated into existing and new small machine designs, or acquired as a standalone package for those users who do not want an integrated system. According to the supplier, this new system includes the first all-electric discontinuous dosing system for microcellular foaming. Pricing for the new Series III MuCell system including SCF System, interface kit, and all operating rights will cost between $55,000-$75,000.Injection molding machine OEMs Engel and Arburg already have said they will offer the Series III system as an option with their smaller machines. A key design feature of the Series III MuCell system is that gas compression is accomplished with an electric drive motor instead of air-driven pumps. Trexel projects this will help to reduce the required maintenance activities by 50% compared to the Series II MuCell system. In addition there is almost no in-service demand on shop air.
