Ancient & Cutting-Edge Technology

Nov 15, 2022

Many people don’t know that investment casting is both an ancient and cutting-edge technology. Also referred to as lost-wax casting, investment casting is one of the oldest metal-forming processes in use today, though we’ve come a long way since it was invented. Evidence of its use dates back 5,000 years for making idols, jewelry, ornaments, and other items. Early investment castings have been found in Pakistan from 4,500 years ago and in Tutankhamun’s tomb in Egypt from before 1,300 B.C. Today’s technology and metallurgical knowledge have greatly improved investment casting, but the basic process remains very similar.
