2012
Development of Variable Valve Timing Parts on the Exhaust Side for Eco-Friendly Car
- Diamet Corporation
- The suitable design for powder metallurgy, the abolition of side hole machining & the abolition of use of seal material, pressing the stop hole, the design to combine of two parts was efficient and the high expectation of future expansion were evaluated.
Development of sintered bearings for the poppet valves for EGR system
- Diamet Corporation
- The development and mass production of new material to be dispersed 6 mass% graphite homogeneously, the freshness of chamfering of different shape inside diameter and the fulfillment of change from other material with huge cost saving and the high expectation of future expansion were evaluated.
The development of a complicated shape part for torque converter by utilizing CNC compacting technique
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- It was evaluated that the comlicated shape parts which compression ratio of boss & brim portion and thickness were different were mass produced by using CNC technology extremely and the fact that changed to P/M technology from other production method which currently became main stream was excellent and also mass production amount was high.
Development of Sintered Coupling for Engine Balancer for Clean Diesel Vehicle
- Diamet Corporation
- It was evaluated that by using characteristic of powder metallurgy to keep high density at projection portion mass-produced the machining-less net-shape with high hardness and high accuracy, and also the use was clean diesel which was expected to expand in future.
Development of additional function to the parking support parts for CVT
- Hitachi Chemical Co., Ltd.
- By using characteristic of powder metallurgy, the fulfillment of one body which was two bodies before, the mass-production of complicated shape parts with non-symmetric shape and thin-thickness with step that compression ratio was different which was difficult to press compaction by using special molding dies structure and the improvement of toughness of die material were evaluated
Development of the powder metal part for the lightweight centrifugal cluth
- Hitachi Chemical Co., Ltd.
- It was evaluated that by examining and improving the each process like molding dies design, compaction, sintering, sizing and heat treatment, huge diameter, thin thickness and rugged parts was mass-produced by P/M
Low-noize oil-impregnated bearing for fan motor of super-slim mobile note PC
- Porite Corporation
- It mass-production of bearing which had both anti-abrasion property and intimacy which usually were trade-off relation, fulfillment of cost reduction, to change the area of small dynamic pressure bearing to oil impregnated bearing, use of mobile note PC market and number of production amount ware evaluated.
Segregation-free mixed powder for free-cutting to achieve a sintered material with excellent drilling performance
- JFE Steel Corporation
- The improvement of tool-life, environment improvement by avoiding sulfrizing treatment and the expectation of future expansion were evaluated.
Development of precision cam sprocket with sensors for an idle reduction system
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- The fulfillment of one body, the production of non-symmetric parts which body thickness was different by press compaction by using special molding dies design and special press movement and the design of weight reduction were evaluated.
The valve seat material of adding higher wear resistant hard particles
- FINE SINTER CO., LTD.
- The new technology of dispersion of oxide by adding rate-earth metal, the material cost reduction and expectation to use other valve seat material were evaluated.
Sintered brake lining for high-speed railroad vehicles on local lines
- FINE SINTER CO., LTD.
- The material design to be considered not only brake property but also feeling of riding, use of railroad area and the expectation of future expansion including foreign countries were evaluated.
