As our company has a wealth of experience in processing various automotive spring products, we received an urgent request from the customer for the production of automotive spring products. We produced approximately 300,000 pieces for this urgent request, while also managing other mass-produced items, and we were able to meet the customer's requirements and deliver the desired production quantity. By supplying approximately 300,000 parts this time, we were able to contribute to the Japanese automotive industry by providing alternative parts supply to Japanese automotive manufacturers without stopping their production lines. As a result, we responded quickly to the urgent short-term request and maintained high quality, earning a "Special Contribution Award" from the customer. *For more details, please download the PDF or contact us.
