2022
Eco-friendly parking parts with laser hardening
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Significant cost reduction by net shape compaction of integrated two parts into one and by laser hardening on only the necessary section which reduced emission of CO2 not using quenching oil was appreciated. Such improvements both in cost competitiveness and environmental friendliness particularly for rapid growing EV industry are also expected to expand the PM market.
Development of housing sprockets for electric VVT that achieves both high hardness and high accuracy
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- High hardness with high dimensional tolerance achieved by introduction of induction hardening in extremely limited area and development of the tailormade grinding wheel which enabled the tight tolerance of groove width and effective range of it were appreciated. These technologies are applicable to other products besides VVT, which may contribute the expansion of PM market.
2021
Development of parking part of transmission for PHEVs
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Significant cost reduction by challenging change of design including compaction direction is technically highly appreciated as fit in the design award section. Such an idea in design may enlighten part designers. On top of it, expected growth of market needs in similar EPB system due to the electrification of vehicles is appreciated.
Development of Soft Magnetic Powder Cores for Axial Gap Motors
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Mass production of the powder magnetic cores for an axial gap motor is highly appreciated as it is technically innovative and contributes to PM Industry. Each elemental technology, like compaction, bolt hole machining and electrostatic painting was elaborated and the integration made it possible an epoch-making mass production. Further expansion for motors including automotive market is expected.
High efficiency electric oil pump parts for HEVs clutch engagement (high pressure application)
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Significant improvement of dimensional precision of the rotor applying 50% reduction of compaction tooling clearance and a new uniform powder feeding was appreciated. The other point of appreciation is the change of the conventional Al die-casting pump body to PM which contributed to solve the thermal expansion gas between Al and Fe and the contribution to expand the use of PM.
Development of Sprocket Drive for One-Motor Hybrid
- FINE SINTER CO., LTD.
- Integrated elemental technologies of improved compaction supported by CAE analysis, optimization of single coil single shot induction hardening and the phrasing process were appreciated. Significant cost competitiveness against forging was achieved and more penetration into HV is expected.
Development of button parts for shale gas drilling tool
- Porite Corporation
- Pioneer market development of shale gas industry which PM component manufactures are not familiar with was appreciated at first and the idea to exploit low ductility of sintered material as preferable destructivity was highly appreciated. An excellent example of new market development along with cooperation with the customer was valued.
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.
