関工範 Company Profile

Die set, steel die set, press mold components, jig processing products, specialist in die set mold products.

Seki Kouhan Co., Ltd. was established in Taisho 13 (1924) by the previous owner, Mr. Seki Mikiyoshi, in Togoshi, Tokyo, starting the production of pillar gauges, screw gauges, and more. Since then, we have upheld technology and trust as our motto for many years. We have manufactured agricultural parts, refrigerator components, bearings, and other products, but due to the changing needs of the times, our manufacturing focus shifted around Showa 45 (1970) to the production of mold plates and die sets, which continues to this day. We will continue to develop together with our clients, improve our technology, and actively engage in our work. Thank you for your continued support.
