2011

Development of Low Noise Sintering Gear which is better than the Plastic Gear

Development of Low Noise Sintering Gear which is better than the Plastic Gear
Porite Corporation
It was evaluated that with good use of characteristics of sintered parts like control of metallic structure and low density to fulfill low noise, by high dimensional accuracy of gear, lower noise than insert plastic gear and cost saving were accomplished and the parallel development in future was expected.

Development of the lightweight type sinter-diffusion bonding career by new assembly shape

Development of the lightweight type sinter-diffusion bonding career by new assembly shape
Hitachi Chemical Co., Ltd.
It was evaluated that by changing the shape of sintered diffusion bonding face from diameter direction to rotating direction, bonding strength was up and light weight was fulfilled and also design freedom of large parts was expanded and future development was expected.

Base valve case that has realized high performance and low cost

Base valve case that has realized high performance and low cost
Fine Sinter Co., Ltd.
It was evaluated that to have absorb prevention mechanism, the transcribe technology of small concave shape to high accurate sheet face by sizing was developed and production amount was huge, and also contribution to industry because of expectation of future expansion was high.

Development of thrust plate for variable timing system

Development of thrust plate for variable timing system
Diamet Corporation
It was evaluated that the flatness like grinding surface of Φ77face was fulfilled by improvement of production process, not by using machining process, and market expansion by usage expansion of sintered parts by high dimensional accuracy technology cultivated by this technology was expected.

Net shaping of PM component for the reclining seat of automotives

Net shaping of PM component for the reclining seat of automotives
Diamet Corporation
It was evaluated that by the invention of compacting method and use of adequate barreling process, the dimensional accuracy and good surface roughness were kept without sizing and machining, and the cost saving by two piece compaction and production of simple process was fulfilled and the market was expanded.

Oil-impregnated Sintered Bearing for Ultra High Speed motor

Oil-impregnated Sintered Bearing for Ultra High Speed motor
Porite Corporation
