Plastics Industry 4.0 provides a sophisticated insight into the development of the plastics industry in terms of digitalization and Industry 4.0, i.e. the Fourth Industrial Revolution. The background to these increasingly important topics is discussed along with provision of the prerequisite knowledge regarding process complexity and modeling as well as data acquisition to build the foundation of data driven digital processes. Furthermore, the facets of so-called cyber-physical systems including their key components and interfaces are discussed and illustrated using industrial application as well as scientific use cases. Aimed at decision makers in the plastics industry, engineers in industry, including those in R&D and process and product development, as well as researchers and students in universities, this book provides the inspiration to connect with Plastics Industry 4.0, and thereby stimulate innovation in companies, processes, products, and research.
