The book is structured according to the study plans of universities of applied sciences, divided into two main chapters: injection molding processing and injection molding machines. The content focus of the processing section is on the principles of part formation and their impact on part quality and production time. Consequences for process control are derived from this. The description of the machines emphasizes the structure and variations of the injection molding machine. The most important peripheral devices, including automation concepts, are presented. In addition to thermoplastic processing, the specifics of processing cross-linking materials (thermosets and elastomers) are also addressed. The authors are specialists in the field of injection molding technology, with expertise gained through research activities and professional practice at machine manufacturers, processors, and in toolmaking.
