Traditionally practitioners have shared standard practices and learned tricks of the trade to develop sophisticated molds that often exceed customer expectations. However the lack of fundamental engineering analysis during mold design frequently results in molds that may fail and require extensive rework produce moldings of inferior quality or are less cost effective than may have been possible. Indeed it has been estimated that on average 49 out of 50 molds require some modifications during the mold start-up process. Many times mold designers and end-users may not know how much money was left on the table . The word engineering in the title of this book implies a methodical and analytical approach to mold design. The engineer who understands the causality between design decisions and mold performance has the ability to make better and more informed decisions on an application by application basis. Such decision making competence is a competitive enabler by supporting the development of custom mold designs that outperform molds developed according to standard practices. The proficient engineer also avoids the cost and time needed to delegate decision to other parties who are not necessarily more competent. The book has been written as a teaching text but is geared towards professionals working in a tightly integrated supply chain including product designers mold designers and injection molders. Compared to most handbooks this textbook provides worked examples with rigorous analysis and detailed discussion of vital mold engineering concepts. It should be understood that this textbook purposefully investigates the prevalent and fundamental aspects of injection mold .
