Awards and Commendations

The award was given in recognition of the high comprehensive strength that brings together elemental technologies, such as improved forming processes supported by CAE analysis, optimization of single coil single shot induction hardening, and introduction of phrasing processes. Significant cost reductions compared to forging have been achieved and greater penetration into hybrid vehicles is expected.

The award was given in recognition of the development of a material that realized a balance between wear resistance of the contact strip itself and aggression to the trolley wire, which are required characteristics having a trade-off relationship, by optimizing hard particles, solid lubricants, and matrix. Actual train test results demonstrated significant improvement and sales expansion is expected in the future.

The award was given in recognition of the realization of undercut compaction using a conventional press mechanism instead of a complicated mechanism, and the unique idea of localized die lubrication to prevent die galling. Wider use of a similar mechanism is expected.

Improving raw material powders and die structures enables compaction of ratchet shapes with large steps as well as thin-walled long shapes, and laser quenching of the waved ball groove end face ensures required characteristics. Realization of such parts with complex shapes that require a high level of technology was widely recognized. Such complex shapes tend to be avoided conventionally, however, the fact that mass production has been achieved through a number of countermeasures demonstrates the progress of near-net manufacturing technology for sintered products.
Further powder metallurgy market expansion is expected in the future by replacing other manufacturing processes.

Thanks to our unique equalizing contact pressure mechanism, we were able to improve the performance of the brake lining, including improved brake performance and wear resistance which contributes to safety and cost and received wide recognition for our achievement. In particular, the improved brake performance makes it possible to respond to emergency braking in the event of an earthquake, which was recognized as contributing to improving the safety of high-speed trains.
Market expansion for high-speed trains equipped with this brake lining is expected to expand in the future.

We achieved multifunctionality of the product by realizing design-in and die structure improvements, and have received wide recognition for contributions to significant cost and weight reductions of user units.
This successful development demonstrated the superiority of sintered parts as parking lock parts for next-generation hybrid vehicles, and further market expansion is expected in the future.

The originality of the technology that made it possible to complete the total process time in 44 minutes from compacting to sizing, including shortening the sintering time, and the novelty of a compact production line were widely recognized.

The novelty of the method to disperse oxides by adding rare earth metals, the reduction in material costs, and the potential for use in other valve seat materials were widely recognized.

The award was given in recognition of the technology to combine near-net-shape manufacturing and green machining to produce components with complex outside shapes with inside helical gears, and the technology to develop new sintered mechanical components for the variable valve lift, which will continue to expand in the future.

The development of Mo alloy steel powder that achieved high fatigue strength in a general-purpose mesh belt furnace was widely recognized for its contribution to the production of low-cost, high-fatigue strength parts at sintering manufacturers.

The award was given in recognition of the technological expertise to manufacture complicated shapes by press compaction and sintering, the versatility of application to similarly shaped products, and its adoption as important automotive safety parts.

The key to increasing the speed of railway vehicles is the brake lining. The achievement in practical application of the brake lining product that can handle a maximum speed of 350 km/h was widely recognized.

The award was given in recognition of the technological expertise to manufacture high-density stainless-steel parts with inclined surfaces by preventing die galling and achieving density balance through ingenuity in the die.

The award was given in recognition of the development of a mass-production technique for high density mechanical structural parts by combining the warm compaction method and original die lubrication method and applying it to complicated shapes. Development of this technique is expected to expand in the future.

The award was given in recognition of the first mass production of a three-dimensionally shaped automotive motor core with excellent recyclability that meets users' demands for smaller motors, by taking advantage of the features of powder compaction, as well as the development of the market for soft magnetic parts applications for automobiles, which is expected to expand in the future.

The award was given in recognition of the technological expertise to produce composites of pressed powder core and resin, which increased the added value of parts, as well as its application in electric power steering parts, for which demand is expected to expand in the future.

This award was given in recognition of the practical application of a thin-walled, multi-step, complex-shaped product by taking advantage of the merits of CNC press, as well as using multifunctionality achieved by integration as a characteristic of powder metallurgy.
