Latest Patents

Hakoyama holds a patent titled "Method for manufacturing high precision slugs." This invention describes an advanced process for creating high precision metal slugs through a cold forming technique. The process includes a preforming step that involves cold forging a metal column starting material with specially designed upper and lower metal dies. This initial stage produces a barrel-shaped primary product characterized by high parallelism at both ends. Following this, the primary product undergoes an upsetting step, where it is crushed while maintaining its parallelism to yield a secondary product. Finally, an ironing step reduces the outer diameter of this secondary product, resulting in a high precision slug that closely matches the desired final product's outer diameter.
