INJECTING MOLTEN METAL INTO A MOLD

摘要

Air voids within a die casting may be minimized by controlling, during the shot process, the venting of gas from the shot tube through a shot tube opening with the proper size at a proper location, and the movement of metal within the shot tube to avoid entrapped gas and prematurely solidified aluminum particles in the molten metal being injected into the die cavity during the shot process.
