Net shape manufacturing of complex multi-level shaped parking parts with two-pcs simultaneous compacting
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- The new ideas of compaction in upside down and simultaneous 2 pieces to avoid seizure supported by optimization of compaction tool with 3D design enabled the perfect net shape, which is highly appreciated. Cost reduction of 50% was achieved by eliminating machining and the simultaneous two-piece compaction increased the cost competitiveness of PM against other manufacturing method, which is expected to increase PM market.
Mass production of high accuracy and thin-wall product for electric VVT
- FINE SINTER CO., LTD.
- Achievement in high dimensional tolerance of the component having irregular configuration and thin sections which need hardening by exploiting CAE analysis was highly appreciated. The technology which solved the PM's difficult issue and the application in the electric VVT system are considered to increase the potential of PM.
Planetary Brazed Carriers for MT with Improved Endurance Fatigue Strength
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- By changing the design from conventional way to the new way which does not use step for elimination of rotation while increasing the bonding interface area and by removing volume in gear sections, the customer's demands of strength and cost were satisfied, which was appreciated. This development showed the PM's ability of solution in design flexibility, reliability of quality and improvement of bonding strength to the customer. It is expected to promote the sinter-brazing technology in e-axle of EV etc.
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.
