Practical and easy to understand, this book describes the injection molding process and the settings of the injection molding machine to produce high-quality injection molded parts. It is intended as a guide for the machine operator and provides clear instructions for process optimization. How exactly does injection molding work? How do you set up the machine optimally? How do you produce a high-quality injection molded part? The book conveys all of this in an easy-to-understand form. The common special processes are described in detail and the necessary additional physical principles are explained. The chapter "Optimization of Quality" describes how quality can be documented and which tools are available for quality optimization. This also includes artificial intelligence (SPC, EVOP). The ever-more important topic of sustainability is also covered in a separate chapter.
