Is this the world's first!? We have succeeded in mass-producing molds by direct engraving on super hard alloys. We offer rivets and contact punches at half the conventional price.
Tokyo Bolt and Screw Machinery has succeeded in mass-producing molds through direct engraving on cemented carbide. As can be understood from the fact that cemented carbide is used for tools and molds to process regular metals, it is an extremely hard metal. Traditionally, machining cemented carbide required "very expensive special machining centers and special cutting tools, which made processing possible but limited in shape and precision, resulting in significant costs." Therefore, it was common knowledge that processing cemented carbide was done through electrical discharge machining. Our company has 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 been able to achieve running costs of less than half compared to conventional methods with 24-hour continuous operation.

basic information
This is a carbide mold for shaping the heads of rivets and button-shaped electrical contacts. It can also regenerate worn molds. Rivets and electrical contacts are used everywhere, mainly in automobiles and electronic components. It is estimated that over 100,000 molds necessary for their manufacturing are produced worldwide each month. Currently, our production level is a few hundred units per month, but our immediate goal is to increase it to 1,500 units, and eventually, we aim to sell to Chinese manufacturers, targeting over 10% market share globally.

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.
