Burn marks are serious defects in injection-molded parts that can result in many defective products. There is thus a great demand for effective systems to reduce these defects in injection-molded products. In this study, we investigate the relationship between gas generation and molding conditions using gas sensors. The results show that gas sensors can be used to monitor burn marks.
