Abstract

Abstract In the article was presented the results of analysis of the nonconformities which occur during the production of PET bottles in the selected company from Poland. The analysis included six process unit operations of forming PET bottles. The aim of the analysis is to present specific corrective and improvement actions based on the results obtained. The article presents a short description of the process of shaping PET bottles for six selected operations. The block diagram of the PET bottle shaping process is presented. Quality management tools were used for quantitative and qualitative analysis. The use of the Pareto-Lorenz diagram allowed for quantitative an approach to the quality problems of PET bottles. The Ishikawa diagram was used to identify potential causes of the most frequent problem. Corrective actions were proposed to improve the quality of PET bottles tested. The research problem has been solved. As a critical element requiring improvement, the competences of employees and the process of operating machines and devices were indicated.
