The ‘system level’ knowledge and design skills needed to create good snap-fit interfaces existed in the minds of self-taught snap-fit experts but was not captured in the literature. New designers of plastic parts wishing to use snap-fit had nowhere to turn unless they were fortunate enough to have access to an experienced snap-fit designer. This book organizes and presents all design aspects of snap-fits with an emphasis on the systems level thinking required to create world-class attachments. Beginning, as well as experienced, product designers will find the information they need to develop snap-fits more efficiently and avoid many common snap-fit problems. The third edition has been thoroughly revised to include new case histories and applications. The text has been extensively rewritten for clarity and user-friendliness and there are many new figures with expert explanations.

Tooling, molding, secondary operations, material selection, evaluation and testing, design, project management, costing, value engineering, international supplier management and enhancement, and more: this book provides a broad insight from the author’s over 40 years of experience in the plastics industry. Aimed at both technical and non-technical personnel involved with plastic product design and manufacturing, this book shows how having the big picture leads to effective solutions and high-quality products. Numerous case studies of product failures exemplify the key concepts. The reader will benefit from the author’s unique depth and breadth of knowledge and experience as a team manager and hands-on contributor in all aspects of plastics, involving extremely robust, mission-critical products. Judicious attention to fundamental engineering principles is always at the foundation but “people issues” are also brought into focus from the author’s background as a long-time international trainer and Six Sigma expert. The book is therefore an essence of all the experience gained along the way: the good, the bad, and the ugly. This book is unique among the many other fine books available in this subject area in that it is the perspective of one who has been in the trenches—as opposed to an academician, scientist, or other professional from a field with narrower scope, such as material science, tooling, or manufacturing. Hence, the HOLISTIC APPROACH. Contents: • Causes of Plastics Failure • The Holistic Approach • Plastic Materials • Design • Tooling Considerations • Processing • Secondary Operations • Part and Tool Costs • Six Sigma Techniques in Plastics • Further Reading and Reference Material With forewords by Glenn Beall, Louis Maresca, and Joe McFadden.

Moulding Masterclass is a compilation of technical articles by plastics injection moulding industry expert John Goff, originally written for magazine publication between October 2009 and July 2013. According to the author, injection moulding processes are frequently developed in the early stages of a product's launch and never revisited. Particularly in today's challenging economic climate where manufacturing costs need to be minimised, it is more important than ever that time is devoted to process optimisation. This collection of 32 articles takes the reader through many aspects of the injection moulding process, from the influence of screw design and speed on melt plasticization, flow and shot consistency, through injection and holding time and pressure, gate sizing, runner systems, mould cooling, clamp forces, systematic process control and more. Each discussion combines theory with recommendations and practical examples seen in diverse manufacturing environments. John Goff has almost 40 years' experience of injection moulding and has seen all sides of the process, having been a senior university lecturer, process engineering manager, consultant and trainer. He has written numerous books and articles, presenting complex technical information in a simple, coherent fashion.
