Pressure Assisted Processes for High Integrity Aluminum Castings

Abstract

Low pressure is perhaps the longest-running pressure assisted process for manufacturing high integrity structural aluminum castings and recent variations on that process have enhanced its capability. Still, high pressure die casting has long dominated the manufacture of aluminum castings and variants like high-vacuum, squeeze and semi-solid now make die casting quite suitable for even the most demanding high integrity applications.

This paper provides a review of prominent pressure assisted casting processes, and discusses underlying principles and fundamentals. Representative examples of products successfully made by each process are provided.
