Lost foam casting (Also known as the EPC) is casting similar to the size and shape of the foam model bond into a model cluster, brush fire-resistant coating and drying, buried in the vibration moulding dry quartz sand, casting in a negative pressure, so the model gasification, liquid metals occupy the model position, after cooling to form new casting method castings.

Lost foam casting Using LFC technology, investment in equipment to reduce 30%--50%, cutting the cost can decrease 10%--30%, originally required machining holes. hole can be cast directly, this would greatly reduce Assembly costs, while also reducing investment in processing equipment.

Lost foam casting Divided into two categories: sheet metal forming evaporative pattern casting and mould foaming in EPC. The main feature of the former is: 1)Without mould, instead of using commercially available foam sheet, made with CNC machine tools block, and then bonded together. 2)Resin sand or water glass sand is often used for filling sand, dry sand molding was also used. The main features of the latter are, formed in a mold and vacuum dry sand molding. It is mainly used in small castings production. Usually refer to this method as Lost Foam Casting,Short title LFC Method.
