What are advantages of investment casting

Investment casting the biggest advantage is due to the investment casting with high dimensional accuracy and surface finish, so can reduce machining work, only in parts a little higher requirements on the parts machining allowance, and even some castings only grinding, polishing allowance, don't need to machining can be used. Using investment casting method, therefore, can be a lot of saving machine tool equipment and processing time, greatly saving metal materials.

Investment casting method is another advantage is that it can cast all kinds of alloy of complicated casting, special casting high temperature alloy castings. Such as jet engine blades, its streamlined profile and cooling with lumen, hardly formed by machining process. Using investment casting process can not only achieve batch production, ensure the consistency of the castings, but also avoid the residual knife lines of stress concentration after machining.
