An apparatus for producing a metal formed product comprises a molten metal-holding furnace; a semisolidified metal-producing mechanism; a cooling member-restoring mechanism arranged adjacent to the semisolidified metal-producing mechanism, for applying a restoring treatment so that chillers have a desired function; a forming machine for forming semisolidified metal to have a predetermined shape; and an articulated robot capable of transporting a crucible to the molten metal-holding furnace, the semisolidified metal-producing mechanism, and the forming machine. The semisolidified metal-producing mechanism includes first to third agitators. The cooling member-restoring mechanism includes first to third treating sections. These components are arranged in a direction of back and forth movement of the articulated robot. Accordingly, it is possible to efficiently obtain the metal formed product having a high quality.

Apparatus and method for producing metal formed product

A fiber reinforced plastic drive shaft comprising a pair of metal joint members, an inner plastic layer extending over the entire length of the drive shaft and holding the metal joint members in both end portions thereof, and an outer plastic layer formed on the inner layer. The inner layer comprises continuous carbon fibers helically wound at 45-75 degrees to the axis of the drive shaft, while the outer layer comprises continuous fibers such as carbon fibers, glass fibers, polyester fibers and aramide fibers helically wound at 5-40 degrees to the axis of the drive shaft. The drive shaft has a greatly increased torsional strength and damping effect. The maximum damping effect is provided when the outer layer is formed only over the joint members.
