While Lost Foam Castings are generally more expensive than forged parts, or parts made by other casting processes, they make up for the higher cost through the reduction in machining due to the tight, near-net shape and net shape tolerances achieved as cast. Many parts that require milling, turning, drilling, and grinding can be Lost foam cast with only 0.020" - 0.030" finish stock. Again, it is imperative that all involved discuss what features can be cast to determine final finished product cost.
