Mold design is one of the most challenging tasks in injection molding and it is crucial for successful profitable operations. The book compiles the experience of many seasoned designers and presents tried and tested molds that run successfully in production. For this fourth edition, changes and supplements were once again undertaken with the aim of representing the state of the art.The book is written by practitioners for practitioners, describing problem solving in the design and the manufacture of injection molds. This classic belongs on the desk of everyone involved in designing or building injection molds. After a general explanation of the types of molds, runners and gates, mold temperature control, ejectors, special designs, standard mold components, and materials for molds, the book presents 108 illustrated examples of good, tested mold design. These are classified as standard molds (two-plate, split cavity, stripper-plate, and three-plate), stack molds, hot-runner molds, cold-runner molds, and special design molds. Review: " ... illustrates selected problems of injection mold construction with interesting and commercially tested solutions ... ranging from the simplest technology to the most complex multistage molds. Adding to its value ... is the inclusion of shortcuts and practical tips." Modern Plastics
