Features: This book comprehensively and thoroughly discusses the modern hot runner technology in injection molds. It introduces the types, selection, and usage conditions of hot runners, and analyzes operational errors. Using numerous structural diagrams, it explains the design principles, manufacturing, and assembly of nozzles, gates, and runner plates. It fully elaborates on technologies related to hot runners, including the flow and thermal properties of plastics, the rheological balance of melt filling the mold, temperature control, and thermal equilibrium. It also reflects the new hot runner technologies emerging in the development of plastic processing engineering. Additionally, it covers the hot runner applications in special injection processes such as high-temperature plastics, thermoplastic elastomers, and multi-component plastics. It also introduces specialized hot runner technologies like stack injection molds, fabric-lined inserts, and fusion-free joints. This book is practical and innovative, serving as a technical reference for engineering and technical personnel engaged in plastic processing and injection mold production management, design, and manufacturing. It is also suitable for reference reading by faculty and students of colleges and universities in plastic processing engineering and related fields.
