Stabilize quality by implementing process improvements! Achieving better yield within the process also leads to cost reduction.
We would like to introduce a case where quality improvement was achieved through engineering enhancements. The material is A2017. The red-framed area is prone to distortion due to machining stress, and during the initial production, there were many out-of-tolerance defects in strict tolerance areas such as parallelism of 0.02, height of 15 +0.02/0, and hole position of 8.3 +0.02/0, resulting in a significantly poor yield. As a countermeasure, we proposed annealing treatment. By performing annealing treatment on the material before machining, there was an additional cost for the treatment, but we were able to reduce distortion, which led to a decrease in defects, allowing us to deliver stable quality to our customers. [Challenges] ■ The material is A2017, and the red-framed area is prone to distortion due to machining stress. ■ There were many out-of-tolerance defects in strict tolerance areas, resulting in a significantly poor yield. *For more details, please visit our website or feel free to contact us.
