Latest Patents

Hiraiwa’s listed patent, “Method for Manufacturing Press-Molded Part,” describes first press-molding an intermediate product and then press-molding that intermediate product to create the finished part. The intermediate product includes a top panel, pre-vertical wall, pre-lateral wall, pre-bottom wall, and outward bulge. In the second operation, the outward bulge—a plate-like portion contiguous with the three pre-walls—is deformed to form the finished part, which includes a top panel, vertical wall, lateral wall, bottom wall, three ridge lines, and a convergence portion. This staged process provides a defined approach to shaping the part’s walls and structural features.
