A case study: Plan-Do-Check- Act (PDCA) cycle to reduce defects in manufacturing process of injection moulding in plastic parts / Nur Farahim Aziz

The PDCA Cycle is a set of procedures for gaining useful learning and expertise in order to enhance the production of a product or process over time. PDCA is a four-step iterative quality improvement and productivity improvement approach that is commonly used to improve business strategy. The PDCA cycle is a step-by-step procedure that begins with tiny changes to assess potential effects on processes before progressively progressing to larger and more targeted changes. One of the manufacturing processes that has an obvious and possibly the most defects in production is injection moulding. One of the reasons this topic is picked out it is because a manufacturing process such injection moulding produces a lot of products from plastic parts production yet the defects from this manufacturing process seems to be unavoidable. The importance of PDCA cycle is that it lets companies to generate hypotheses about what needs to change, test these hypotheses in a continuous feedback loop, and gather useful knowledge and learning. The expected results in this project is to improve the product’s productivity and quality by reducing the defects through PDCA. So in this project problems like delivery time, cost or in this topic, mainly defects they will be tackled to be fixed by using the PDCA Cycle.
