Injection Molds For Beginners Second Edition

This applications-oriented book describes the construction of an injection mould from the ground up. Included are explanations of the individual types of tools, components, and technical terms; design procedures; techniques, tips, and tricks in the construction of an injection mould; and pros and cons of various solutions. Based on a plastic part ("bowl with lid") specially developed for this book, easily understandable text and many illustrative pictures and drawings provide the necessary knowledge for practical implementation. Step by step, the plastic part is modified and enhanced. The technologies and designs that are additionally needed for an injection mould are described by engineering drawings. Maintenance and repair, and essential manufacturing techniques are also discussed. Now if full color, this second edition builds on the success of the first, with updates and small corrections throughout, as well as an new expanded section covering the process chain.

Understanding Injection Molds opens up the entire subject of injection mold technology, including numerous special procedures, in a well-grounded and practical way. It is specifically intended for beginners, young professionals, business owners, and engineering students.The chapters are clearly structured and easy to understand. The book is designed so that it provides a complete basic knowledge of injection molds in chronological order as well as day-to-day guidance and advice. The numerous color figures facilitate a rapid understanding of the content, which is especially helpful to the beginner who wants to learn about injection molds quickly.In the forefront of the description are thermoplastic molds. Divergent processes for thermoset or elastomer molds are explained at the end of each chapter. This book captures the current state of the art, and is written by authors who are specialists in the field.The second edition has been updated and improved throughout.

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.

Economic success in the plastics processing industry depends on the quality, precision, and reliability of its most common tool: the injection mold. Consequently, misjudgments in design and mistakes in the manufacturing of molds can result in grave consequences. This comprehensive handbook for the design and manufacture of injection molds covers all aspects of how to successfully make injection molds from a practical as well as from a theoretical point of view. It should serve as an indispensable reference work for everyone engaged in mold making. "...an example of how books should be written ... will be used by molders, mold designers and mold makers and will become a standard." (Polymer News) Contents: · Materials for Injection Molds · Mold Making Techniques · Estimating Mold Costs · The Injection Molding Process · Design of Runner Systems · Design of Gates · Venting of Molds · Heat Exchange System · Shrinkage · Mechanical Design · Shifting of Cores · Ejection · Alignment and Changing of Molds · Computer-Aided Mold Design and Construction · Maintenance of Injection Molds · Measuring in Injection Molds · Temperature Controllers · Mold Standards · Correction of Molding Defects · Special Processes - Special Molds

Here is a comprehensive guide for everyone engaged in the design or manufacture of injection molds. Written for engineers, plastics professionals, and students, the book is intended to assist in the mold-making process and help avoid costly mistakes. The authors cover all aspects, including material selection, fabricating cavities and cores, general mold design, hot runner systems, venting, design, demolding techniques and devices, maintenance, hardware, construction procedures, and more. All topics are presented in a thorough, detailed manner, based on the authors' extensive practical experience. The emphasis is on the application of designs and concepts in real manufacturing settings. In addition, the book can be used as a text for those who have little detailed knowledge or practical experience with injection molding or mold-making procedures. The new second edition draws on the most recent literature as well as extensive research and development at the Institute for Plastics Processing at the Technical University of Aachen, Germany.
