A lot of PM parts have been used in automobile because of the cost advantage. We have been promoted "Loss-zero activity" such as promoting net shape manufacturing and decreasing rejects in production process in order to increase the competitiveness of PM parts.For net shaping, we developed technology to prevent slip-crack which is a slipped flat plane get into lower density portion1) and simultaneous sinter-brazing technology that enabled mass production of net shaped synchronizer hubs and PM planetary carriers. In order to decrease rejects, we developed and adopted aeration powder filling technology that decreases weight variation. Furthermore, we are trying to develop apparent density (A.D.) sensor to measure A.D in a filler shoe and filled cavity in-situ to eliminate weight adjustment process after die-change.
