Mold defect reduction for the aluminum wheels

Abstract

The mold defect appears on the face of the wheels as lack of foundry material mainly on the spokes, windows, hub area, and bead of the wheels. The purpose of this project is to improve product quality by reducing mold defects. This involved identifying and isolating the primary causes of problems that directly affect the cost of poor quality, determine the root causes and implement effective corrective actions. On the last semester basis, there was a total of $ 149, 835 USD as a result of scrap. The initial goal is to reduce the cost of poor quality (COPQ) by 50% to achieve annual savings of $ 74,917. After the changes performed up to know, we have a weekly savings of 1560.00 U S. Dollars, for a total at least of 78,540.00 because of some of the changes are being implemented or the effect of the implemented changes is not jet reflected.
