New Design
2021
Sintered bearing for suction motor of robot vacuum cleaner
- Porite Corporation
- Enabling a silent high speed bearing stands for 25,000rpm by combining specific design, material and oil impregnation and replacement of ball bearing were appreciated. Further penetration of the robot vacuum cleaner and application in home appliances which demand silence are expected.
2020
Sintering of bearings for automotive LED headlight cooling fans
- Porite Corporation
- While ensuring the better performance than high performing ball bearing or fluid bearing, cost reduction to half is appreciated. The adoption to LED head light system which is expected to grow is also appreciated.
Cost-down by using shape molding for the curved groove of parking lock part
- FINE SINTER CO., LTD.
- Realization of an undercut compaction with the conventional press mechanism but not with complicated mechanism and the unique idea of introduction of local mold wall lubrication to avoid galling were appreciated. Wider use of the similar mechanism is expected.
Sintered part for motorcycle transmission
- DIAMET CORPORATION
- Enabling an area of sinter forging by the ordinary press and sinter process and the density of 7.4 g/cm³ in the pin shape were appreciated.
2019
Sintered brake lining for new high-speed railroad vehicles
- FINE SINTER CO., LTD.
- The improvement of the brake lining such as better brake performance and wear resistance was realized by the unique equalizing contact pressure mechanism, which contributed to the safety and economics of the braking system. This contribution was highly rated. In particular, the improved brake performance enabled the emergency braking in case of earthquakes, which contributes to the safety of the high speed trains. The market of high speed trains equipped with this brake lining is anticipated to grow.
Development of Double teeth Sprockets with the application of Green machining
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Highly difficult intermittent green machining of the outer teeth of the sprocket realized by setting the machining condition based on the consideration of machining stress direction and adoption of proprietary cutting tools was highly rated. This contributed to the reduction of product's cost. Although green machining has issues like chipping of products and etc., this may show the evolution of it. Cost reduction exploiting this technology is expected to drive PM to expand the market.
Development of the parts for the variable displacement oil pump
- DIAMET CORPORATION
- Realization of the high precision components by improvement such as the compaction tools designed by using FEM analysis of compaction process was rated high. In case of the vane rotor having the large height of 30mm, the tight tolerance of the grooves was still achieved without finish machining. As the variable displacement oil pump contributes to improve the fuel economy, it is expected to be equipped in more vehicles and the market is anticipated to grow.
Development of Lightweight iron-based Sintered Carriers that can replace Aluminum products
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Successful replacement from aluminum casting was rated. The weight reduction by aggressive cut-off volumes while ensuring the demand of torsional torque was evaluated. The crucial quality control of jointed components, is conducted by an ultrasonic flaw detection, which is considered to the further improvement of the quality assurance. This is an excellent example of the replacement from cast aluminum component by exploiting the cost merit of PM. Further development to other application is anticipated.
Development of Sinter Hardened 4WD Cam Parts with High Bending Fatigue Strength
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Omitting process by introduction of sinter-hardening and improvement of material and modified shape were rated high. Break through the strength issues of sinter-hardened material may open the possibility of further cost reduction by adding another cost reduction method. Applying this method to similar cases may promote the replacement from other competitive manufacturing methods and grow the PM market.
Development of sintered oil-impregnated bearings for Electric Parking Brake (EPB)
- DIAMET CORPORATION
- Ultra fine shapes like boss root less than R0.2 mm and O-ring protection shape realized by optimizing the tool configurations and improved process was rated high. On top of them, adoption to the component of automotive electrification which is expected significant growth, is evaluated. EPB is said to the first step to brake by wire and its penetration is in progress. The market of sintered oil-impregnated bearing is anticipated further expansion by this successful case.
