WHAT SIZE RANGE OF PARTS CAN BE PRODUCED BY THE INVESTMENT CASTING PROCESS?
A. Investment castings can be produced in all alloys from a fraction of an ounce (such as a dental brace for a tooth) to over 1,000 pounds (complex aircraft engine parts). Of the approximately three hundred investment casting foundries nationwide, most cast parts are in the ounces to 20 pound range. Presently a larger number of foundries are increasing their capability to pour larger parts, and pieces in the 20-120 pound range are becoming quite common.
