    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.
