This thesis explores the problems affecting product quality while using the ARBURG Allrounder 320C injection-molding machine. The methodology employed for this study is qualitative in nature and consists of an extensive literature review, analysis of case studies, and examination of machine operation data, along with interviews with machine operators and technicians regarding important aspects that affect the quality of their products.
The findings indicate that while there is generally a good degree of stability in the machine parameters, the largest contributor to repeat defects tends to be mold-related problems. Additionally, as the data was collected, it was found that camera-based systems used to detect defects provide much more effective efficiency for inspection purposes and also reduce the amount of manual work done by operators to verify the quality of a manufactured product. This suggests a more holistic approach for improving the quality of a manufactured product through the use of integrated systems, which will provide a further basis for mold maintenance, control of the injection molding process, and performing automated inspections.
