Patent ID: 8387678

Claim:
A mold system comprising: a first sprue; a second sprue; a pouring basin arrangement for selectively feeding the first sprue and the second sprue; a mold cavity; a first gating system having a feed that provides fluid communication between the first sprue and a first portion of the mold cavity; a second gating system having a feed that provides fluid communication between the second sprue and a second portion of the mold cavity, wherein the feed of the second gating system feeds the mold cavity above the feed for the first gating system; a first stopper associated with the first sprue that regulates fluid flow through the first sprue; a second stopper associated with the second sprue that regulates fluid flow through the second sprue; a sensor positioned at a predetermined height of the mold cavity to determine fluid level within the mold cavity; a controller in communication with the sensor; wherein a signal from the sensor to the controller indicates fluid at the first predetermined height in the mold cavity indicating that the first portion of the mold cavity is filled, the controller operates the first stopper to restrict a flow of fluid through the first sprue while unblocking the second stopper from the second sprue, initiating a flow of fluid through the second sprue to allow fluid to fill the second portion of the mold cavity.
