Best practices for making high integrity lightweight metal castings - molten metal composition and cleanliness control

Abstract

To make high integrity lightweight metal castings, best practices are required in various stages of casting and heat treatment processes, including liquid metal composition and quality control, casting and gating/riser system design, and process optimization. This paper presents best practices for liquid metal processing and quality assurance of molten metal in both melting and mold filling. Best practices for other aspects of lightweight metal casting will be published separately.
