Abstract
A molten metal mold and bottom block system, including apparatus and method embodiments, which may include a mold cavity framework with a first side, a second side opposite the first side, a third side, and a fourth side opposite the third side, each side including an inner surface and the inner surfaces defining a mold cavity, and wherein one or more of the sides are movably mounted relative to the second side, and are controllably moved during the casting. This system may also include embodiments wherein the castpart produced has a tapered form at one or both of the castpart ends. Aspects of this invention may be considered to be a castpart shrinkage management system or a castpart form or profile control system due to the advantage of increased controls of castpart form during the casting process.
