This project takes a microscopic look at all raw material, machinery, and practices that effect the screw cap process of wine products in order to highlight and eliminate the causes of defects. The approach for this project involves the analysis of process capability for raw material to achieve its required dimensions. This project also displays methods of attaining appropriate machinery settings, and provides a basis for operating standards. Many quality engineering applications are used throughout this study, revealing the decision process for analyzing said applications.

The studies in this project found uncontrolled dimensions in the suppliers’ caps and bottles and a present need for adjusted operational standards and machinery settings. A variance of nearly 21% was witnessed during operator setup on the machinery and a method for operator improvement was implemented. This project provides methods to eliminate defects in order to better meet Six Sigma quality standards.
