Die Cast Engineering: A Hydraulic, Thermal, and Mechanical Process
A frequently misunderstood technology, die casting is considered the shortest route between raw material and near net shape. For many decades, high pressure die casting was viewed as an art based upon "seat of the pant" strategies. However, many of these crude reactions actually worked because the fundamental process is quite forgiving of eccentricities. Exploring these reactions with scientific logic, Die Casting Engineering presents a broad study of each procedure in the die casting process and clearly outlines its basic science and principles.
This guide is written in a reader-friendly and logical format by an experienced authority in quality and productivity enhancement, tooling design, metal feed system analysis, temperature management, and environmental regulation. While its scope is broad and covers the many facets of die casting, the book's main focus is on function, problem identification and solution, and strategic logic. Generously illustrated, it provides a comprehensive explanation of why high pressure die casting is reliable, predictable, and teachable.
