Quality Assurance
In November 1997, we obtained ISO 9001 certification as a specialized manufacturer of automotive parts and industrial machinery equipment, serving as a core pillar of Japan’s industry. Since then, we have consistently advanced all processes from product development to manufacturing in accordance with this system.
Over 80% of the parts we manufacture are critical safety components. Guided by our motto, “Delivering 100% quality products to our customers,” we ensure reliable performance and quality through thorough in-process quality control, including 100% inspection and the implementation of FP (poka-yoke) measures.
Status of Environmental Management System Implementation
Our company is actively promoting the implementation of an Environmental Management System (EMS). We have obtained ISO 14001 certification at our Head Office Factory and Hanyu Factory, establishing a foundation for environmental management.
Centered on this initiative, we are actively advancing environmental conservation activities and the development and sales of environmentally conscious products.
