Ensuring quality prior to pouring of the various aspects of the aluminum casting production process, the quality of the molten metal is perhaps the most controllable

摘要

Metalcasting facilities must maintain considerable control over their processes to ship high-integrity castings reliably and on time. But, many of those processes are highly influenced by external factors. In any product, five main factors influence casting quality-four of them are often out of the metal-casting facility's control, First, the casting requirements must be set by the end-user, the product designers. In the best of circumstances, this is a cooperative effort between the customer and the caster, but often it is not. Second, the proper metal alloy must be selected-again not necessarily in the control of the casting producer-that will meet the engineering requirements of the casting, Third, the casting process is selected, which controls the fourth tenant in this series-the microstructural response of the casting-which in turn plays a vital role in the product's capability.
