Features: This book introduces the basic principles and methods of pattern materials, foam plastic mold manufacturing, coating technology, investment casting process design, investment casting equipment, environmental protection in investment casting, and defect analysis in investment casting. It also explores the relevant theories of casting formation, such as the aspiration and slag-skimming mechanism of liquid metal in the main feeder, the fluid dynamics mechanism, dynamic heat transfer mechanism, filtration and purification mechanism, and shrinkage mechanism of liquid metal in the investment mold. Additionally, it explains the formation mechanism of casting surface roughness, the formation mechanism of invasive porosity, and other theoretical foundations of investment casting, thereby justifying the design principles of the gating and riser system and the selection of production process parameters. Production examples are provided for illustration, enabling readers to fully grasp the development overview of investment casting. This book emphasizes both theoretical rigor and practical production applicability, making it suitable not only for engineering and technical personnel but also for researchers in this field.
