Sumitomo Electric Wins “JPMA Awards”

At the 35th Japan Powder Metallurgy Association (JPMA) Awards (in fiscal 2013), “Development of the parking component used in the transmission for PHEV” was awarded a New Product Award (in the design category); and “Development of low cost pure iron-based soft magnetic composite core for automotive reactor” and “Development of high-precision gear used in the vehicle attitude control” were also awarded New Product Awards (in the process development category).

 

■Development of the parking component used in the transmission for PHEV

This technology features a 50-mm long product with a gradient portion in the inside diameter that is molded, and was highly valued. The fact that it is used in the newly developed transmission for PHEVs and that future growth is expected was also highly rated.

 

■Development of low cost pure iron-based soft magnetic composite core for automotive reactor

The cost reduction through using fine pure iron powder and improving compacting technology was acknowledged. The material change for the reactor core assembled into the booster for the motor drive system of hybrid cars from laminated iron plates to green compacts was highly acclaimed.

 

■Development of high-precision gear used in the vehicle attitude control

It was highly regarded that the high precision performance equivalent to Class 3 in tooth lead error and Class 2 in tooth profile error were realized for these PM gears, both the pinion gear and ring gear, by reviewing the manufacturing process of tools and dies.
