Abstract
A compound cast product is formed in a casting mold ( ) having a mold cavity ( ) sized and shaped to form the cast product. A plurality of injectors ( ) is supported from a bottom side ( ) of the casting mold ( ). The injectors ( ) are in fluid communication with the mold cavity ( ) through the bottom side ( ) of the casting mold ( ). A molten material holder furnace ( ) is located beneath the casting mold ( ). The holder furnace ( ) defines molten material receiving chambers ( ) configured to separately contain supplies of two different molten materials ( ). The holder furnace ( ) is positioned such that the injectors ( ) extend downward into the receiving chamber ( ). The receiving chamber ( ) is separated into at least two different flow circuits ( ). A first molten material ( ) is received in a first flow circuit ( ), and a second molten material ( ) is received into a second flow circuit ( ). The first and second molten materials ( ) are injected into the mold cavity ( ) by the injectors ( ) acting against the force of gravity. The injectors ( ) are positioned such that the first and second molten materials ( ) are injected into different areas of the mold cavity ( ). The molten materials ( ) are allowed to solidify and the resulting compound cast product is removed from the mold cavity ( ).
