What is lost foam casting? Lost foam casting process

2020-8-20  Lost foam casting is a type of evaporative pattern casting. This method is quite similar to investment casting which uses wax instead of foam in the pattern making process. The foam pattern was first used in metalworking in 1958.

The process - Lost Foam Council

The Lost Foam casting process (LF casting process) is a sand casting process for the production of especially complex metal components where other casting processes failed or only lead to unsatisfactory results. The LF casting process enables the production of prototypes as well as small or large series.

Lost Foam Casting omnidexcastings

Lost foam casting is a delicate process. Patterns made from foam can easily be damaged or distorted, therefore all foam patterns and molds must be handled with care. In the pouring stage, the molten metal must reach temperatures of above 1000°F in order to fully ‘dissolve’ the foam pattern and produce a complete casting piece.
