Casting Methods

Double Poured Static CastingCentrifugal Casting

Many years of experience enable Karl Buch to utilize highly developed casting procedures. Centrifugal casting, as well as double poured static casting, are our specialties. The shell and core layers are cast exactly symmetrical - the ideal basis for thermal stability and shape. Heat treatment of the rolls guarantees optimal thermal stability and behavior.
