Design and Manufacture of Plastic Components for Multifunctionality: Structural Composites, Injection Molding, and 3D Printing presents the latest information on how plastics manufacturers are increasingly being driven towards carbon emission reduction, lightweighting, and cost savings through process integration. These technologies have the potential to revolutionize future products with built-in functionality such as sensors, smart packaging, and damage detection technology for everything from milk bottles and salad packaging to automotive bumpers and plane fuselages. This book introduces the three core manufacturing methods for multifunctional materials, composites, injection molding, and 3D printing, all processes facing challenges for the implementation of new technology. Users will find a book that brings together both process and material advances in this area, giving process engineers, designers, and manufacturers the information they need to choose the appropriate material and process for the product they are developing. - Provides an introduction to the latest technologies in the area of multifunctionality, enabling engineers to implement new breakthroughs in their own businesses - Gives an understanding of the processes that need to be considered in both design and manufacture of future devices, while using materials from a broader palette than used in existing manufacturing processes - Includes best practice guidance and flow charts to aid in material and process selection - Covers revolutionary future products with built-in functionality such as sensors, smart packaging, and damage detection technology for everything from milk bottles and salad packaging to automotive bumpers and plane fuselages

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.

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.

How easy life would be if only moldings were the same size and shape as the mold. But they never are, as molders, toolmakers, designers and end users know only too well. Shrinkage means that the size is always different; warpage often changes the shape too. The effects are worse for some plastics than others. Why is that? What can you do about it? The Handbook of Molded Part Shrinkage and Warpage is the first and only book to deal specifically with this fundamental problem. Jerry Fischer’s Handbook explains in plain terms why moldings shrink and warp, shows how additives and reinforcements change the picture, sets out the effect of molding process conditions, and explains why you never can have a single ‘correct’ shrinkage value. It goes on to demonstrate how to alleviate the problem through careful design of the molded part and the mold, and by proper material selection. It also examines computer-aided methods of forecasting shrinkage and warpage. And most important of all, the Handbook gives you the data you need to work with. Authoritative and rooted in extensive industrial experience, the expert guidance contained in this handbook offers practical understanding to novices, and new insights to readers already skilled in the art of injection molding and mold making Contains the answers to common problems and detailed advice on how to control mold and post-mold shrinkage and warpage Case Studies illustrate and enrich the text; Data tables provide the empirical data that is essential for success, but hard to come by

This book describes an effective framework for setting the right process parameters and new mold design to reduce the current plastic defects in injection molding. It presents a new approach for the optimization of injection molding process via (i) a new mold runner design which leads to 20 percent reduction in scrap rate, 2.5 percent reduction in manufacturing time, and easier ejection of injected part, (ii) a new mold gate design which leads to less plastic defects; and (iii) the introduction of a number of promising alternatives with high moldability indices. Besides presenting important developments of relevance academic research, the book also includes useful information for people working in the injection molding industry, especially in the green manufacturing field.

This reference guide was originally prepared in 1990 as a convenient pocket sized resource for use in Injection Molding. This information is most useful by personnel who work in the injection molding field including press operators, technicians, engineers, designers, mold builders, etc.There are many reference data tables regarding plastics data, statistical methods, engineering calculations and valuable training for personnel in the IM industry. The book includes basic part design, trig tables, calculations for thermal expansion, thermal exp coeffs, SHCS data, torque specs, shrink data, cooling time equation, mold debug guidelines, melt index data, resin density data, many tables of process guidelines, process development techniques, calculating heat load & water flow requirements, pipe data, conversion factors, transformer & motor current, PM & safety, basic statistics, equip selection guidelines and more.This 4th Edition has been reformatted at 5.5 inches wide x 8.5 inches tall in 2011 for print sales.
