Vacuum Casting | About AFS and Metalcasting| AFS

In many cases, casting metal in the natural environment produces quality results, but in some instances metalcasters have figured out how to act against nature in order to achieve optimal properties from their cast components. By using a vacuum to evacuate air in an enclosed area, either to produce a mold, pour castings or melt metal, metalcasters can successfully produce complex, difficult castings. Because a vacuum is used in various ways during different steps of the metalcasting process, the term “vacuum casting” can be unclear. An aerospace engineer may associate vacuum casting with the method of melting high-alloy or superalloy material under a vacuum to avoid oxidation of the highly reactive elements. But an engineer working with pumps and impellers may think of the mold-filling method using differential pressure caused by a vacuum to draw metal into the mold cavity. This article will take you through a few of the vacuum casting methods used in a range of molding processes.  From thin walls to dimensional accuracy, vacuums can use the unnatural to make certain metal castings possible.
