Innovation and Recent Development in Casting Techniques

Metal casting processes are being adopted for manufacture of parts for equipment and machines for thousands of years. Over the years improvements and innovations have been deployed to make the processes more productive to increase output and at the same time making them cost effective. This paper describes three of the casting processes viz. Lost Foam Casting, Mould less Casting and Ice Casting Formation. The processes, the materials considered for the moulds, advantages and disadvantages as the case may be are explained.
