We will develop new mold technologies aimed at miniaturization and weight reduction of parts, as well as precision machining technologies for new materials.
Tokyo Bolt and Screw Co., Ltd. has been manufacturing various cold forging and forging molds since its establishment in 1961, earning high praise from customers as a mold manufacturer known for high precision, long lifespan, and high quality. We specialize in processing difficult materials, particularly cemented carbide, and have produced molds for small screws (shaft diameter 0.3mm), cemented carbide two-piece punches, and forming molds for complex-shaped parts. These achievements are the result of over 50 years of history spent working closely with our customers to address their challenges. We will continue to uphold our motto of "never saying it can't be done" and are committed to responding broadly to our customers' requests. 【Product Line】 ■ Cold forged molds for screws, electronic components, and automotive parts ■ Precision press molds made of cemented carbide ■ Cemented carbide molds "Tokyo-ACE" ■ Punches and pins made of cemented carbide ■ Superalloy hard drawing (wire drawing) dies ■ High-speed punches manufactured by Nippon Precision Industries ■ Rolling dies ■ Machine parts made of cemented carbide, such as nozzles for winding machines *For more details, please refer to the PDF document or feel free to contact us.

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.
