Mold for micro parts
A carbide mold used for shaping micro parts through cold forging processing. Our company specializes in fine and deep hole machining, capable of handling hole diameters down to 0.15 millimeters and depths of about 6 millimeters. We are also skilled in irregular shapes and steps. Even with extremely fine dimensions, we can perform lapping on the inner surface of the holes to achieve a mirror finish.

Applications/Examples of results
Forming micro parts through cold forging (header processing, progressive press processing, etc.). Our company supplies molds for the world's smallest screws (shaft diameter 0.3 mm). Please leave the molds for ultra-fine screws, rivets, lead pins for electronic components, and more to us. Recently, we have also received orders for extremely small rubber molding molds. We believe that our processing technology can be applied to precision parts related to the medical and semiconductor fields, which are advancing into the micro world.
Company information
Tokyo Bolt and Nut Company has focused on the hidden potential of cemented carbide, refining technologies for machining irregular shapes, fine holes, deep holes, and lapping processes for cemented carbide. We were once a "mold manufacturer," but our goal is to be recognized by our customers as a "ultra-precision machining manufacturer." Recently, we have succeeded in mass-producing molds with direct engraving on cemented carbide, a world first! Cemented carbide is an extremely hard metal. Traditionally, machining cemented carbide required "very expensive special machining centers and special tools, making it possible to process only under certain conditions, resulting in high costs and limited shapes and precision. Therefore, it was common knowledge that machining cemented carbide was done through electrical discharge machining. We have conducted years of research with the goal of mass-producing cemented carbide molds at low cost, specifically aiming for direct engraving and omitting lapping. We have now achieved both. As a result, while maintaining quality equal to or better than traditional methods, we have achieved a running cost of less than one-fifth of the conventional method with 24-hour continuous operation. In the future, we will utilize this technology to contribute to the miniaturization and lightweighting of parts in aerospace, precision machinery, and medical fields.
