Company information
Nagano Forging Co., Ltd. was established in Nagano City in 1953, and in May 2003, we celebrated our 50th anniversary, continuing to this day. Nagano Forging specializes in the processing and manufacturing of heat-resistant and wear-resistant materials, known as difficult-to-cut materials, and has acquired manufacturing technologies that are challenging to complete in overseas production. By developing our own equipment related to this, we have established unique technologies. We have obtained ISO 9001, an international standard for quality assurance, and thoroughly manage the quality of critical safety components in the automotive industry, providing high-quality products that our customers can trust. Moving forward, we aim to recruit young engineers and incorporate new ideas to develop new technologies, as all employees unite to grow as a technical group. We are confident that advancing our technology alongside the wonderful nature of Shinshu will contribute to the local community.
