Companies can economically produce high volumes of parts with the investment casting process. In fact, long runs are usually when investment casting is most beneficial. This is because of the related costs. While the tooling costs of investment casting can be significant, they are spread across more parts, which lowers the per-casting cost. In addition, investment casting reduces or eliminates costly and time-consuming machining in many cases. Investment casting is often the best choice for short runs for many reasons, but the real savings are in volume.
