摘要

The Precision Sand Casting Process (PSCP) is used to manufacture components in many Internal Combustion Engine (ICE) and Battery Electric Vehicle (BEV) applications. PSCP along with High Pressure Die Casting (HPDC) and Gravity Semi-permanent Mold (GSPM) are all viable casting processes for aluminum automotive applications. In recent years the implementation of an integral chill in PSCP has refined the microstructure in targeted areas, which in turn improves both tensile and fatigue properties, potentially giving it a performance boost over the competing casting processes mentioned. However, chill implementation can have drawbacks which could adversely impact other parts of the final casting. This work outlines the impact on the PSCP with and without a chill, on the casting’s overall characteristics and heat treatment response. From there the authors will compare the possibilities with the PSCP against competitive casting processes for the same automotive applications.
