Introduction of examples that achieved multiple improvements such as cost reduction, weight reduction, elimination of heat treatment, and process reduction!
The customer was troubled by excessive processes, costs, and the effort required for corrections due to core runout caused by the two-part configuration. Therefore, we proposed the integration of the two parts using work hardening through cold forging. As a result, we achieved multiple improvements, including reductions in cost, weight, elimination of heat treatment, process reduction, and the elimination of correction work due to excellent concentricity. 【Case Overview】 ■ Issue: Excessive processes, costs, and effort for corrections due to core runout caused by the two-part configuration. ■ Solution: Integration of the two parts using work hardening through cold forging. ■ Effects: Achieved multiple improvements such as reductions in cost, weight, elimination of heat treatment, process reduction, and elimination of correction work due to excellent concentricity. *For more details, please refer to the PDF document or feel free to contact us.
