Process capability analysis is a part of the statistical process control, which is designed to monitor and regulate the process. The aim of statistical control is to maintain the manufacturing process at a level so that produced products have the required quality and meet the customer requirements. The contribution provides a closer look on the capability of flange forging process for the automotive industry. In the automotive industry there are strict requirements on product quality, therefore it is necessary that all manufactured products meet the specified quality requirements. In the case study is introduced the analysis of factors influencing the process capability in flange manufacturing. Based on the findings from conducted analysis it is to expect an improvement of the forging process capability based on proposed measures.Keywords: quality improvement, process capability, flange production, forging
