JPMA Awards
The JPMA Awards started in 1979, and is the 45th in 2023. The purpose of the JPMA Awards is a spread of the PM industry.
Categories of the JPMA Awards are as follows.
- ・New Products (New Design/New Materials/Process Development)
- ・New Powders
- ・Equipment Development
Since 2003, the Grand Prix has been given to an especially excellent product.
Effort Prize has been given to some products with the feature from among a left out of selection products.
2023
Practical Application of High Frequency & High Strength Reactor Core
- FINE SINTER CO., LTD.
- Daido Steel Co., Ltd.
- The product was highly appreciated for its ability to reduce the product size by approximately 30% and the unit volume by 13% by developing a new material that overcomes conventional issues and significantly improving its properties. The product was also highly evaluated for its efforts to reduce product cost by approximately 30% through keeping improvement throughout the manufacturing process. This product is expected to be used more widely in electric systems, which are expected to continue to increase in the future.
Development of high-precision parts for new mechanism semi-active suspension
- FINE SINTER CO., LTD.
- Using advanced technology, the complex and high precision assembled parts that are difficult to achieve with competing manufacturing methods, were highly evaluated for meeting strict functional requirements and keeping cost control. This product is expected to continue to be in demand even as the electrification of vehicles progresses, and the technology is expected to be applied to similar parts.
Oil-impregnated bearing unit for CPAP equipment that achieves low sliding loss at high speeds
- Porite Corporation
- The product was highly appreciated for meeting user requests by integrating various technologies as well as the sintered seal cap: the medium relief shape, dimples, optimizing choice of material and impregnated oil. In addition, the market is expected to expand in the future as it has been adopted in new equipment in the medical industry and is a technology that contributes highly to society.
Development of Long/complex Shape Rotor and Slide for Variable Displacement Vane Pumps
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- The development of a new technology that double-shrink-fits the side core with high stress concentration into the die, the realization of a long/complex shaped product with high precision, and the use of multiple reference points in compaction tool design, are recognized as creative breakthrough for solving the problems. This development is expected to expand capability of PM in the precision of large and long items.
Aluminum bronze powder for powder metallurgy
- Fukuda Metal Foil & Powder Co., LTD.
- This development is highly evaluated for realizing mass-production of sintered aluminum bronze, which has been thought to be difficult to commercialize, and for expanding new option for powder metallurgy materials. With this new material, PM parts in new fields and applications that have not been put to practical use in the past are expected.
Sintered parking parts for electric vehicles
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- This development was evaluated for its ability to significantly reduce costs while maintaining high functionality as a development that contributes to the basic actions of a car (run, turn, stop). This part was also highly recognized for its close communication with customers to optimize design, which led to robust production. This product is expected to be widely adopted as a cost reduction technology for products continue to grow in the future.
Oil-impregnated Sintered Bearings with Excellent Wear Resistance by Applying Density Gradient
- Porite Corporation
- The density gradient inside the bearing was created by optimizing the shapes of product in the manufacturing processes, that improved strength and created an oil supply system using capillary force. This development was highly evaluated and the market for use as thermal management components is expected to expand in the future.
