Abstract: A method for manufacturing a light alloy wheel that includes a substantially annular rim part and a disc part that is joined to one edge of the rim part on an inner side and is to be attached to an axle. The method includes a molten metal pouring step for pouring a light alloy molten metal from a sprue opened into a mold cavity formed into a shape of the rim part, and a forced cooling step for, after the molten metal pouring step, forcibly cooling the light alloy molten metal poured into the mold cavity formed into the shape of the rim part such that one predetermined cooling unit of a plurality of cooling units provided along an entire circumference on an outer side or an inner side of the mold cavity formed into the shape of the rim part is first operated and an other cooling unit thereof is then operated.

Abstract: The electrodeposited metal plate peeling off machine according to the present invention comprises a hammering apparatus, a peeling off apparatus and a transfer means installed throughout the foregoing two apparatuses for the purpose of intermittently transferring a cathode plate composed of the electrodeposited metal plates and the base plate holding said electrodeposited metal plates thereon from the hammering apparatus to the peeling off apparatus, wherein the hammering apparatus consists of hammering means, accommodated in a sound insulating box of closed type construction employing sound insulating materials and the peeling off apparatus is equipped with nozzle pipe having a slit-like nozzle, respectively, which is directed to the upper edge of the electrodeposited metal plate and disposed practically parallel to said upper edge at an appropriate distance, blowers for continuously supplying low-pressure air to said nozzle pipes, and roller conveyers disposed below the peeling off means and composed of rol
