Investment Casting

Abstract

Investment Casting is a metal casting process which employs an expendable pattern and one piece non metallic mould. This process is also known as Precision Casting because it eliminates the parting line and reduces the machining cost. Sometimes, this process is also known as lost wax method. Although all metals, namely ferrous as well as non-ferrous can be casted by this process, it is most suitable for expensive, hard and high strength metals and alloys, which are difficult to machine. This also includes Stainless and Tool Steels
