What Are Vacuum Investment Castings?

Vacuum castings are the metal parts that are produced by the vacuum casting method. They are different than typical investment castings due to the technique that is used to create these metal parts. The process begins by placing a two-piece mold in a vacuum chamber. The vacuum then draws the molten metal into the mold. Finally, the casting is solidified in an oven and the mold is removed in order to release the final product.
