A microcellular foam processing system for a reciprocating screw injection molding machine has been successfully developed (40). The necessary conditions for creating and maintaining a single-phase solution in the overall system of the plasticizing unit are a supercritical fluid delivery unit and a hydraulic unit.

An overall systems approach is the key to successfully implementing a microcellular foam process. The necessary modifications and the component designs that are required for a microcellular foam molding machine have been described. The important components are the plasticizing unit, injection unit, hydraulic unit, clamp unit and supercritical fluid unit (40).
