Brass heteromorphic hollow stick "mitoseru"

 
――――――――――― Winning the Kyoto medium and small-sized business technology prize award for excellence ―――――――――――
New hole space brass stick in consideration for processing efficiency, the global environment

With mitoseru

The hole space brass stick indicating the color that is golden attractiveness and the solid look.
Kaimei copper elongation develops it, and it is named which "I can foresee it in a product" "mitoseru" by a meaning to "be able to foresee the future".
I realize reduction in cost by shortening of reduction, the processing time for correspondence to the shape that "mitoseru" is complicated, and is special and processing loss.
In addition, I develop the kadomiresu brass stick which does not include cadmium in consideration for environment with a person and cope with RoHS regulation.
"mitoseru" is a new brass dash found in the coming times.

A note: I assume unit price of mitoseru 100. ※Remarks: The processing more than 10mm in length is difficult by the general processing, but can produce mitoseru to 4,000mm.
