Abstract
The study has investigated key parameter(s), which causes short shot-type defect in the case of a plastic injection moulding process using Shainin DoE methodology. An average rejection rate of around 11% was recorded over a period of three months, due to the presence of short shot-type defect for a bulb holder component (E27). Shainin’s DoE methodology of Red X, based on progressive elimination search principle, was adopted to identify key parameter (s), which caused such defect among the variables selected for the study. Selective tools from Shainin’s DoE methodology were adopted and a particular variation reduction roadmap was prepared to investigate the process. The influential factor identified was the injection time, a solid Red X, i.e. a dominant variation causing variable.
