WHY CHOOSE INVESTMENT CASTINGS?
Investment castings have significant advantages over other manufacturing technologies as summarized in the Manufacturing Process Comparison Chart at the bottom of this page. In general, investment castings demand the fewest design restrictions of any metal-working process. The more demanding the part configuration is, the more advantageous the investment casting process is. A summary of the unique benefits of the investment casting process follows: • Design Freedom: The investment casting process allows the designer the flexibility of nearly infinite alloy choices, and great flexibility in external and internal configurations. In addition, unlike other casting methods, there are no draft requirements in the investment casting process. • Reduced Machining: Investment castings are produced to close tolerances and near-net size. There is little secondary machining required, thus offering savings in machining time and material costs. Even some splines and threads can be cast. • Reduced Fab
