The injection molding tool as a central element. The injection molding tool consists of different functional complexes as a manufacturing unit, which fulfill essential tasks in the injection molding process. High reliability is expected from the injection molding tools in daily use. A well-thought-out planning and design of the molded part and tool is a prerequisite for this. The standard work aims to familiarize students and all those involved in the development process of a component with the rules for designing molded parts and tools to produce functional, cost-effective, and visually appealing components. Now newly available in its 7th edition. The current edition builds on previous versions but has been completely revised, restructured, and expanded.
