The history of lost foam casting

The lost foam casting (LFC) process originated in 1958 when H.F. Shroyer was granted a patent for the cavity-less method, using a polystyrene foam pattern imbedded in traditional green sand.  The polystyrene foam pattern left in the sand is decomposed by molten metal.  The molten metal replaces the foam pattern and precisely duplicates all of the features of the pattern.

Kritha Convertors prides itself in casting quality products for 15 years.
