Gastrow Injection Molds: 108 Proven Designs

The original edition of Injection Molds proved to be an invaluable aid for everyone involved in the design and construction of injection molds. This new edition represents a fully revised, expanded, and up-to-date version of this popular guide. It incorporates the latest advances, such as the advent of computer-aided engineering, which have revolutionized the field, but it is written with the added perspective provided by years of experience in mold making and design. A general introduction familiarizes the reader with basic design details, including the types of injection molds, runners and gates, temperature control, types of ejectors, standard components and specialized designs, material varieties, and so forth. This is followed by over 100 examples that illustrate the types of molds described. These are presented according to classification: standard molds (two-plate, split-cavity, stripper-plate, and three-plate molds), stack molds, hot-runner molds, cold-runner molds, and special-design molds. The various hot-runner systems and the large molds that have gained in importance have been given special attention. Like the first edition, this book is a valuable resource that belongs in the library of every mold maker. It covers almost every problem likely to be encountered in the process, with a wealth of practical tips and proven shortcuts. The tested designs offered here are shown in full drawings, with detailed descriptions.
