"A stainless steel or steel tube with several small holes " may seem simple to most people, but there is only one company in all of Japan that has the skill to consistently produce a high quality product. That company is Kato Seisakusho, the company that can do the press work that "can't be done."

That "simple" tube is actually used as a cover or housing for technologically advanced sensors in automobiles. To create this tube, a flat sheet is drawn into a cylindrical shape and then round, elliptical and square holes are created in its sides. This tube is now complete, free of burrs and scratches, and will require no further machining. In addition, all of the work was completed on a single machine and even though the sheet of metal was drawn over ten processes, there is almost no reduction in its thickness. The know-how and methods for achieving this are closely guarded trade secrets of Kato Seisakusho.

Kato Seisakusho also designs and manufactures its own dies and automated equipment for manufacturing products, and is working with steel manufacturers to develop stainless steel and steel materials that are best suited for the deep drawing process as the company strives towards the extreme limit of a +/-0 margin of error in our products. Kato Seisakusho is a company that challenges the limits of press work.

The corporate motto of Kato Seisakusho is to "manufacture quality products that meet our customers' requests in the desired volume by using the best method in the best location, and do it safer, faster, and at a lower cost." To this end, the company's management had the foresight to quickly establish overseas facilities and take a proactive stance in the process of globalization. Kato Seisakusho continues to expand the potential of press technology.

The business philosophy of Kato Seisakusho is to understand its customers' needs and take the lead in creating their products. To put this philosophy into practice, requires bringing together all of the essential elements: equipments, dies, lubricants, raw materials, and of course, a world class workforce.
Kato Seisakusho's employees have the "artisan's touch," a realm that cannot be achieved through digitalization in which a skilled craftsman can feel the texture of a die with their hands, or locate the smallest stress point with their eyes. Only workers like this can make it possible to attain products with the unique +/-0 margin of error.

With its all original ideas and outstanding technology, Kato Seisakusho is consistently involved in research and development of new manufacturing technique to set the future realization.
