Squeeze casting is considered a âhigh integrityâ process, and has given
materials and design engineers a new alternative to conventional casting
techniques: gravity permanent mold (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 aluminum 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.
