The emergence of squeeze casting process for aluminum alloys has given material and design engineers a new alternative to conventional casting techniques: gravity permanent mold (GPM) and conventional (high velocity, high pressure) 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 provides both a description of the HVSC squeeze casting process and examples of select components manufactured at CONTECH.
In this study, the mechanical (tensile, impact, fracture toughness, fatigue strength) and wear properties of various aluminum alloy squeeze castings are also compared with those of gravity permanent mold and conventional die-castings. Results indicate that mechanical and wear properties of aluminum squeeze castings are superior to those of gravity permanent mold and conventional die-castings.
