Process of manufacture of the copper elongation section

An original product is developed by a self-developed machine. As for the long history, it is proved the trust. I challenge various needs in a certain technique.
Technique of the artisan and original production process, it which were systematized are our prides. The special alloy, low birth system to meet by multi-kind production with a special shape in small quantities does not permit the following of other companies. The Kaimei unique product producing the original world always keeps moving forward towards the everlasting future.
From dissolution, the casting of the billet to extruded various correction, I produce on an assembly line.
The extrusion dies which hold now more than 10,000 kinds.
I am proud of more than 80% of shares in building hardware in the whole country and produce a great variety of products among other things.

Process of manufacture
