We would like to introduce a case where we were able to provide a product that meets your satisfaction through our know-how and trial and error. Company T was looking for a subcontractor for ring-shaped components (φ900×φ300×H300 Wt1300kg, quantity 50) to be used in their products. They required turning (fit tolerance) and milling processes, keyway machining for the inner diameter, and preferred a "one-stop solution" from raw material to finished product. Leveraging our know-how and the strength of our "one-stop solution," we assisted in "problem-solving." 【Case Study】 ■ Issues - Subcontracting for large diameter rings - Satisfaction with machining accuracy - A procurement source capable of "one-stop solution" from raw material to finished product ■ Solution Our strength lies in "integrated production" that can handle everything from raw materials. We repeatedly refined our approach to meet their needs. *For more details, please refer to the PDF document or feel free to contact us.
