Injection Mold Design Handbook

An injection mold is the heart of any plastics molding work cell. Understanding injection mold design is therefore fundamental to the success of the molded product and the molding operation. The Injection Mold Design Handbook guides the mold designer, engineer, project manager and production manager through the step-by-step process of injection mold design using more than 600 images, tables and illustrations. Since designing an injection mold all starts with the plastic part, the book starts with a focus on designing a plastic part that creates a good mold design. The handbook then focuses on the machine specification and pertinent molding plant considerations. Design of the main components of an injection mold are described in detail along with best practices and important rules of thumb. The key calculations for designing an injection mold are provided along with practical examples of their use. Over 40 reference mold designs illustrate how to apply the guidelines and principles from the book into a completed mold design. Finally the process of testing and gaining customer acceptance of the mold for production is reviewed.
