HIGH INTENSITY PAPER MULBERRY TILE PISTON CASTING METHOD

摘要

PURPOSE: A piston casting method is provided to improve feeding efficiency and to prevent a shrunk hole from generating by increasing a cooling speed and repressing inflation. CONSTITUTION: The high intensity paper mulberry tile piston casting method comprises the steps of:installing a feeder on the upper and the lower parts of the dividing face of a matrix; increasing a feeding temperature by flowing in a molten metal through the feeder; installing a cold metal on the ring groove of the piston cast in the matrix, a pin hole and the upper and part.
