2015
Development of bearing for linear vibration actuator to be used in wearable device
- Porite Corporation
- Technology of forming fine radius to ultraminiature bearing is highly evaluated. The series production monthly 3 million pieces proved penetration of PM material into the cutting edge market of the wearable terminal.
A set of sintered joints for the motor used in valve lift actuator
- DIAMET CORPORATION
- The challenge to realized high precision steam treated component without sizing operation was recognized. Optimizing compaction tool material and compaction condition minimized the distortion caused by springback, and optimizing sintering method and condition improved the scatter of dimensional change which enabled elimination of sizing process.
2014
Development of synchronizer hub with helical gear for DCT
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- The thin, complicated shape parts with helical gear were mass-produced with high density and high dimensional accuracy. Production results were monthly 20,000 pieces. It was evaluated that the new technology and contribution to cultivate DCT main parts which are expected to increase in near future.
Air-compressor component with thin-walled part for electric vehicle
- DIAMET CORPORATION
- Oldham ring with thin flange was successfully produced without machining (net shaped) and lighter weight. It was evaluated that this technology opened the possibility to be used in AC for gasoline car also in future.
Development of sprocket with crank sensor for diesel engine
- DIAMET CORPORATION
- By using the sintering method, it was successfully produced by one body and without machining. It was evaluated that the contribution to P/M industry to change from other production method.
2013
Development of Oil-impregnated Sintered Bearing for Motor of Idle Speed Control System of Small Motorcycle
- DIAMET CORPORATION
- The development for the bearing material which showed sufficient strength when the bearing was pinched and fixed to the motor body and of course keeping slide characteristic and oil retentivity was appraised. In addition, the improvement by the sizing process that could maintain precise dimensions at the time of production and actual mass production results were accepted.
Development of Joint Part for Motor of Electric Power Steering
- DIAMET CORPORATION
- Utilizing PM's advantages, the product was pressed to the net shape with weight saving and high strength, so it was a warded a prize. And converted from forged parts to this product indicated the superiority of the PM technology was also judged.
Mass-production of light weight piston with thinner thickness for motor cycle
- FINE SINTER CO., LTD.
- As for this parts, complexity having thin walls and concave / convex structure was designed to press the net shape by preparing new die and press technology was admitted. Stabilized ability for decrement of the shock absorber, that contributed to improve the performance of motorcycle was evaluated also.
Development of the Sintered Bearing for Battery Cooling Fan Motor, used for a HEV (Hybrid Electric Vehicle) and EV (Electric Vehicle).
- Porite Corporation
- These bearings achieved the coaxiality to 1 micrometer by optimization of tools and dies, the press accuracy and assembling method at the user's production line was admired. A successful point was accepted switched from a ball-bearing to the sintered bearing in the field of HEV, EV which extension could be expected.
Electric Oil Pump Rotors for Use under Silent Environment
- DIAMET CORPORATION
- The new tooth profile of the oil pump rotor was carried out and also the original theory that paid attention to the gap between inner and outer rotors to minimize noise problems was established corresponding to the quietness-related demand of the car. It was accredited to award. These rotors are expected to mount on HEV and the idle-stop system widely in the future.
