This text investigates the technical principles and mechanical requirements necessary for the design and construction of plastic injection moulds. Laszlo Sors, an expert in mechanical engineering, provides a comprehensive framework for understanding the interaction between material properties, thermal dynamics, and mechanical stress during the moulding process. The book synthesizes empirical data and engineering standards to guide practitioners through the complexities of mould geometry and production efficiency.

Engineers and students of manufacturing technology frequently cite this work as a foundational reference for understanding the mechanical fundamentals of injection moulding. While the text reflects the engineering standards of its era, it remains a respected resource for those seeking to understand the core physics of plastic processing.
