Latest Patents

Hisashi Yoshimura holds a patent for a "Method and apparatus for molding a light-alloy wheel." This invention involves a unique apparatus where cores are moved by a cotter through a sliding mechanism. The design ensures that the sliding portion is isolated from molten metal, reducing the likelihood of locking at this critical point. The compact sliding mechanism is strategically placed within the mold top segment, allowing for effective heat dissipation due to the large gap between the cotter and the mold. This innovative molding method enables the cores to be positioned at a retracted position and extended before the molten metal solidifies, effectively eliminating blow holes in the cast wheel.
