Company profile


President Keiichiro Okamura
President Keiichiro Okamura
 The Kaimei copper elongation always stared at the society through a brass variant stick and an aluminum shape. I reached a new century and I always repeated changes and built history of 60 rest of life while the speed of the times accelerated.
 I establish the limited production of diversified products system from the beginning of establishment, and the history that built high technology to a base is the history that I built with a customer. The Japanese economy is included in the 21st century, and management innovation in the low growth is demanded. DNA of the Kaimei copper elongation says that it is always first to supply a better product in that.
 Our company keeps the management that was particular about manufacturing and a person under the no management philosophy that all employees make the dream, and "they bring up a heart" in mind.
 I deepen a business partner, the interchange with the community and will push on toward further development from now on.

Management philosophy

1, superior human resources

The liver of the corporate management is "a person". It is called "Homo sapiens, a thing, money" in company administration, but it is the person that it brings up a person that it handles money to treat a thing.
We Kaimei copper elongation thinks that it is the best shortcut to realize an idea to bring up a person. The superior human resources are "the people who continue growing up" for us. I want to help with the growth well.

2, superior product

"Yes, the thing" is Kansai dialect. Generally, I point to the superior product.
Then, "yes, the thing" should be special why you expressed it in Kansai dialect.
"Yes, is sensible with a thing", and, "thank you," aim at the product which a customer can say to,, "yes, a thing is soft".

3, superior deadline

What I can make contracted request and limited express correspondence into on a deadline is a superior deadline at the same time to deliver it on the deadline when I promised. "Thank you," a customer can give in particular words to the limited express correspondence most.
Generally, with the product which we purchase, it is unexpectedly difficult to have both these two.
We aim at this deadline to share two.

4, superior environment

Environment has many meanings, but for us
 ①I make the products which are kind to the global environment
 ②I promote an approach of Eco for a community
 ③I work on three to make the environment that is easy to act.

5, superior relations

We make many business partners, employees, stockholders, communities and relations.
Communication is important to aim at the better manufacturing,
Construction with such people concerned of relationships is important.
With the superior relations
 ①It was good to make a deal with the Kaimei copper elongation
 ②It was good to enter Kaimei copper elongation
 ③I am pleased together and cry and can be impressed
I point to the relations that can feel this.
