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 book is an update to the first edition compiled and published in 1990 by William Woishnis. A lot has changed in the field since 1990 and a lot has not changed. There are new plastic materials. There has been a huge turnover in ownership of plastics producing companies. There has been a lot of consolidation, which of course means discontinued products. Thus, this update is much more extensive than the usual "next edition." It has been reorganized from a chemistry point of view. Plastics of similar polymer types are grouped into nine chapters. Each of these chapters includes an introduction with a brief explanation of the chemistry of the polymers used in the plastics. An extensive first chapter has been added as an introduction that summarizes the chemistry of making polymers, the formulation of plastics, testing and test methods, and plastic selection. Most plastic products and parts are expected to be used in environments other than room temperature and standard humidity conditions. Chapters 2-10 are a databank that serves as an evaluation of plastics as they are exposed to varying operating conditions at different temperatures, humidity, and other factors. Over 900 graphs for more than 45 generic families of plastics are contained in these chapters. Chapter 11 contains extensive mechanical and electrical data in tabular form. The tables contain data on several thousand plastics. Similarly, Chapter 12 contains thermal data on several thousand plastics. Data from the first edition have only been removed if those products were discontinued, and many products were. Product names and manufacturers have been updated. • Detailed introductions of plastics properties, testing procedures, and principles of plastics design. • The only "databook" available on the effects of temperature and humidity conditions on plastics and elastomers. • More than 1,000 graphs and tables allow for easy comparison between products. • Covers more than 70 types of plastics, and summarizes the chemistry of each type.

Alles zum gleichläufigen Doppelschneckenextruder Bei der Herstellung von Kunststoffen, insbesondere bei der Aufbereitung und Verarbeitung bis zum Fertigprodukt werden Extruder eingesetzt, wobei der gleichläufige Doppelschneckenextruder eine dominante Rolle spielt. Aber auch in anderen Industriezweigen, z. B. der Kautschuk- und Lebensmittelindustrie und zunehmend in der Pharmaindustrie kommen die Gleichdrallschnecken vielfältig zum Einsatz. Eine multifunktionale Maschine Das Fachbuch gibt umfassenden Einblick in die verfahrens- und maschinentechnischen Grundlagen und legt großen Fokus auf Praxisbeispiele. Meist sind die Schnecken modular aufgebaut und können damit sehr flexibel an veränderte Aufgabenstellung und Produkteigenschaften angepasst werden. Für die optimale Auslegung eines Doppelschneckenextruders sind vertiefte Kenntnisse über die Maschine und den Prozess erforderlich. Ein Praxisbuch für Einsteiger und Profis Die zweite Auflage entstand unter Mitwirkung vieler Fachautoren von renommierten Firmen und Hochschulen. Alle inzwischen erfolgten Weiterentwicklungen wurden berücksichtigt. Die zweite Auflage wurde durchgehend neu bearbeitet, ist deutlich erweitert, komplett in Farbe und in neuem Layout.

Die enormen Zuwachsraten in der Kunststofferzeugung und -anwendung erhöhen die Forderung nach aussagekräftigen Mess- und Auswerteverfahren in der Kunststoffprüfung. Durch die Fortschritte in der elektronischen Messtechnik haben sich sowohl die klassischen Prüfverfahren weiterentwickelt als auch völlig neuartige Methoden etabliert. Die Aussagekraft dieser Kenngrößen zur Quantifizierung der Zusammenhänge zwischen der Mikrostruktur und den makroskopischen Eigenschaften wird dargestellt. Zusätzliche Informationen über die ablaufenden Schädigungsprozesse und -mechanismen können durch die Anwendung gekoppelter zerstörungsfreier Kunststoffprüfverfahren bzw. hybrider Methoden der Kunststoffdiagnostik gewonnen werden. An Hand von Beispielen zur Optimierung von Kunststoffen und Verbunden sowie zur Bewertung von Bauteileigenschaften wird ein werkstoffwissenschaftlich begründeter Einblick in die moderne Kunststoffprüfung vermittelt.

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.
