Investment casting is often referred to as near net shape casting as parts with complex geometries, superior surface quality and tight dimensional tolerances can be made with high accuracy using this process.

Investment casting, or lost wax casting, is one of the oldest manufacturing processes still used today, dating back thousands of years to India and Egypt as well as Aztec, Mayan and Chinese civilizations. Early applications for investment casting included small statues, jewelry and arrowheads.

Today's applications include marine propellers, medical implants, aerospace, defense, industrial gas turbines, jewelry, art bronze sculpture, architectural hardware, glass art and more.
