This introduction emphasizes the basic technical information specific to injection molding and the various technical problems faced when working in industry. The reader gains an understanding of machines, molds, injection molds, and the various molding techniques used in the past and today.

Special Injection Molding Techniques covers several techniques used to create multicomponent products, hollow areas, and hard-soft combinations that cannot be produced with standard injection molding processes. It also includes information on the processing techniques of special materials, including foaming agents, bio-based materials, and thermosets. The book describes the most industrially relevant special injection molding techniques, with a detailed focus on understanding the basics of each technique and its main mechanisms, i.e., temperature, mold filling, bonding, residual stresses, and material behavior, also providing an explanation of process routes and their variants, and discussions of the most influencing process parameters. As special molding technologies have the potential to transform plastics processing to a highly-efficient, integrated type of manufacturing, this book provides a timely survey of these technologies, putting them into context, accentuating new opportunities, and giving relevant information on processing. Provides information about the basics needed for understanding several special injection molding techniques, including flow phenomena, bonding mechanisms, and thermal behavior Covers the basics of each technique and its main mechanisms, i.e., temperature, mold filling, bonding, residual stresses, and material behavior Discusses the most relevant processing parameters for each injection molding technique Presents a variety of techniques, including gas and water assisted injection molding, multi component injection molding, hybrid injection molding, injection molding of bio-based materials, and techniques for thermoset

This book in the Plastics Injection Molding series addresses the many facets of running a molding company including selecting the right equipment, identifying costs to determine price, making the most of available resources (including personnel), and complying with industry and quality standards. Also discussed are key company strategies that can determine whether a company operates in the red or is profitable. This book also includes a benchmarking feature that allows decision-makers to gauge their company's competitiveness in comparison to the top 50 molders in the United States.

This book covers the most recent and important developments in advanced injection molding technologies, such as intelligent process control; technology innovations and computer simulation for emerging special injection molding processes like microinjection molding, microcellular injection molding, water-assisted foaming, water-assisted injection molding, and variable mold temperature technologies; conductive polymer foams and composites; injection molding of optical products; and an automated mold design navigation system with integrated knowledge management capability. It is intended to be used as a textbook for both introductory and advanced injection molding courses, as a must-have reference for professional engineers and engineering managers who want to keep abreast of the latest technological developments and applications, and in libraries to serve interested readers from both academic and industrial communities as well as the general public. With chapters written by an international team of experts, this book provides a broad and insightful coverage, complementary to other books on injection molding.

Plastics Injection Molding: Scientific Molding, Recommendations, and Best Practices is a user-friendly reference book and training tool, with all the essentials to understand injection molding of plastics. It is a practical guide to refining and controlling the process, increasing robustness and consistency, increasing productivity and profitability, and reducing costs. This book contains structured information on process definitions and parameters, optimization methods, key points, interpretation of data sheets, among other useful recommendations regarding both technology and design. It also provides analysis of process deviation, defects, incidents, etc. as well as a section dedicated to material selection and comparison. It includes a bonus of downloadable Excel spreadsheets for application to scientific molding, process analysis, and optimization. This book is aimed at injection molding technicians, process engineers, quality engineers, mold designers, part designers, simulation engineers, team leaders, plant managers, and those responsible for purchasing plastic materials.

This book provides a vision and structure to finally synergize all the engineering disciplines that converge in the mold design process. The topics are presented in a top-down manner, beginning with introductory definitions and the "big picture" before proceeding to layout and detailed design of molds. The book provides very pragmatic analysis with worked examples that can be readily adapted to "real world" mold design applications. It should help students and practitioners to understand the inner workings of injection molds and encourage them to think "outside the box" in developing innovative and highly functional mold designs. Contents: · Introduction to mold functions, types, and components · Review of design for injection molding · Cost estimation and optimization · Mold layout design including cavity layout, sizing, and materials selection · Cavity, runner system, and gating analysis and design · Cooling system analysis and design · Venting, shrinkage, and warpage analysis and strategies · Ejection force analysis and ejection system designs · Stress and deflection analysis with structural system designs · A survey of advanced mold designs

This third edition has been written to thoroughly update the coverage of injection molding in the World of Plastics. There have been changes, including extensive additions, to over 50% of the content of the second edition. Many examples are provided of processing different plastics and relating the results to critiCal factors, which range from product design to meeting performance requirements to reducing costs to zero-defect targets. Changes have not been made that concern what is basic to injection molding. However, more basic information has been added concerning present and future developments, resulting in the book being more useful for a long time to come. Detailed explanations and interpretation of individual subjects (more than 1500) are provided, using a total of 914 figures and 209 tables. Throughout the book there is extensive information on problems and solutions as well as extensive cross referencing on its many different subjects. This book represents the ENCYCLOPEDIA on IM, as is evident from its extensive and detailed text that follows from its lengthy Table of CONTENTS and INDEX with over 5200 entries. The worldwide industry encompasses many hundreds of useful plastic-related computer programs. This book lists these programs (ranging from operational training to product design to molding to marketing) and explains them briefly, but no program or series of programs can provide the details obtained and the extent of information contained in this single sourcebook.
