One of the real advantages of the investment casting process is the ability to produce complex parts with little or no machining. Because it is a “near-net-shape” process, it can produce precision castings that even have flawless right angles and other intricacies right out of the mold. Once the molten alloy has cooled, the shell or mold can be broken off of the parts during the knockoff process. In the vast majority of cases, it’s ready to go as-is or with only minor finishing. That saves significant cost and time, and produces better parts.
