Finishing precision cast parts during the investment casting process typically requires far less work and cost than other processes. In many cases, there is no finishing needed at all. This is one of the most significant benefits investment casting’s “near-net-shape” process. If finishing is necessary for specific customer requirements or to achieve the best quality, it usually consists of excess metal removal, surface polishing, heat treating and other similar activities. Near-net-shape parts go a long way to save time, reduce cost, expedites production and increases the consistency of the castings.
