Abstract
In this paper we present a study that was conducted to determine the classification of causes that generate defects in products obtained by injection of plastic material. A classification of the causes of defects is made by applying a quality management tool - the Ishikawa diagram. The causes are grouped into M categories, for defects generated by the design process and for defects generated by the injection process. A new model of the diagram is created by composing two fish skeletons (model 4M + 5M). At the end of the paper, the importance of the Ishikawa diagram is shown.
Highlights
In this paper we present a study that was conducted to determine the classification of causes that generate defects in products obtained by injection of plastic material
The diagram was originally designed with the division of causes into different categories of M, was subsequently Potential causes of defects of plastic products obtained by applied in different fields of activity and so the diagram injection molding was extended to other categories of causes
In this paper we propose a new classification of the causes that generate the defects of plastic products
Summary
In this paper we present a study that was conducted to determine the classification of causes that generate defects in products obtained by injection of plastic material. Another paper, [4], presents the causes for a number of 13 defects of injection molded parts.
