Squeeze casting is considered a 'high integrity' process, and has given materials and design engineers a new alternative to conventional casting techniques: gravity permanent mould (GPM) and conventional (high pressure, high velocity) die-casting. In recent years, the squeeze casting process has been applied to near net shape products requiring high impact strength, high fatigue strength, pressure tightness, or high wear resistance. This paper briefly discusses the squeeze casting technology (P2000TM) at SPX CONTECH and provides examples of the various aluminium alloy safety critical components manufactured. The paper also includes fluid flow simulations and solidification analyses for select components, comparison between predicted and actual microstructures, mechanical properties (tensile and fatigue) based on samples machined from actual castings, and results from strength and fatigue testing of components.
