Headquartered in Japan, we use our precision manufacturing process to go from product design to tool build to mass production. We have control over the entire process from start-to-finish.

    On July 10, 1963, at Fushimi-ku in Kyoto, Akira Konishi invented the module system (total division structure, complete heat hardening treatment, and all precision machining after total hardening) for the purpose of specialized production of precision dies and established DAI-ICHI SEIKO Co., Ltd. The molds that were being made around this time were "high-performance quenching molds." These molds were manufactured for companies supplying makers of electronic computers and integrated circuits, as well as automobiles, televisions, communication equipment, etc.  During this time, we have established a reputation as a manufacturer that makes high-quality and precision molds. Because of this, we succeeded in winning many orders for precision molds and established a solid business foundation with companies not only in Japan, but also in other countries such as the US, Canada, Mexico and Singapore. We far exceeded our original business plan. To continuously improve our technology, we invested in training engineers, requiring them to visit the US, which had the most advanced mold manufacturing technology at that time.
