WHEN IS INVESTMENT CASTING THE APPROPRIATE PROCESS?

Casting is very useful for creating sculptural objects or engineering shapes with complex geometry (such as transmission housings) in metal. Cast parts have a unique look to them, quite different from machined parts. Some shapes which would be difficult to machine are more easily cast. There is also less material waste for most shapes, since unlike machining, casting is not a subtractive process. However, the precision achievable through casting is not as good as machining.
