THE SQUEEZE CASTING PROCESS IS DESCRIBED. This process consists of pouring the molten metal into the diffuser of the casting mold and moving the moveable die of the mold to the side of the fixed die at a constant angular velocity. As the dies draw together, the metal is squeezed upward from the receptacle filling the cavity of the mold between the dies. This method is characterized by the filling of the casting mode by 1 a flow of large cross section, which substantially decreases the hydrodynamic losses while the mold cavity is being filled and 2 the shaping of the cast under conditions of continuous flow of molten metal in the filling of the mold. The continuous flow of molten metal around the solid skins forming on the mold walls results in a high-quality cast.
