Abstract
A mold system and method for producing a casting. The mold system utilizes multiple channels, each channel comprising a sprue and gating system, to feed the mold cavity at different heights. When a lower portion of the mold is filled, a controller is signaled to initiate filling of the mold through a second channel positioned above the lower portion. This mold system desirably provides the hottest molten metal to the last portion of the casting to freeze with or without the use of risers, eliminating casting defects. The system also enables the controlled pouring of dissimilar metal castings.
