Company Profile
Katsui Kogyo Co., Ltd. was established in 1967 as a trading company dealing in forged products. When I first joined the company, it was a small company selling forged products with just one person, but it has now grown into a metal cutting processing company with 24 employees. I believe that this change is solely due to the opportunities and challenges given to us by our customers, and the efforts of each and every employee who supported it.
We realize through our daily work that what cannot be achieved by individual strength alone can be achieved many times over by joining forces with our colleagues. That is why we want to make the manufacturing site a fun and positive place, while everyone cooperates and values communication.
We will continue to take on the challenge of dealing with more diverse materials and shapes while making use of the processing technology of forged and cast products, which has been our strength since our founding. We also want to be "the most reliable company in Japan" that can always quickly recognize the needs of our customers and propose the best processing method.
Encounters and connections are our greatest treasures. We will continue to treasure these connections and take on new challenges and growth, so we appreciate your continued guidance and encouragement.
