Significant reduction in defect rates in automotive parts stamping! Case study on the improvement of independently controlled molds.

A case where original molds were created, achieving improvements in quality and productivity!

We received a request for punching and contour cutting processing from an automotive parts manufacturer, and we would like to introduce a case study of our response. Initially, the designed mold was one where changing the height of the die would alter the height of both the hole and the contour. Even if we wanted to make the hole deeper, the contour would also become deeper, resulting in a high number of defective products. Through repeated trial and error, we improved the stripper plate to create a mold that allows independent processing of the hole and contour, enabling separate control of the die heights for both the hole and contour. 【Case Overview】 ■ Issues - Due to the high order volume for automotive parts, there was a process for removing defective products, which negatively impacted productivity, and there were instances where defective products mixed with good ones led to complaints. ■ Results - By using the newly developed mold for processing, the occurrence of defective products ceased, significantly improving yield and productivity. *For more details, please download the PDF or feel free to contact us.
