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.

Natural fibre composite is an emerging material that has great potential to be used in engineering application. Oil palm, sugar palm, bagasse, coir, banana stem, hemp, jute, sisal, kenaf, roselle, rice husk, betul nut husk and cocoa pod are among the natural fibres reported to be used as reinforcing materials in polymer composites. Natural fibre composites were used in many industries such as automotive, building, furniture, marine and aerospace industries. The advantages of natural fibre composites include low cost, renewable, abundance, light weight, less abrasive and they are suitable to be used in semi or non-structural engineering components. Research on various aspects of natural fibre composites such as characterization, determination of properties and design have been extensively carried out. However, publications that reported on research of manufacture of natural fibre composites are very limited. Specifically, although manufacturing methods of components from natural fibre composites are similar to those of components from conventional fibre composites such as glass, carbon and Kevlar fibres, modification of equipment used for conventional fibre composites may be required. This book fills the gap of knowledge in the field of natural fibre composites for the research community. Among the methods reported that are being used to produce components from natural fibre composites include hand lay-up, compression moulding, filament winding, injection moulding, resin transfer moulding, pultrusion and vacuum bag moulding. This book is also intended to address some research on secondary processing such as machining and laser welding of natural fibre composites. It is hoped that publication of this book will provide the readers new knowledge and understanding on the manufacture of natural fibre composites.

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.

Applied Plastics Engineering Handbook: Processing, Materials, and Applications, Second Edition, covers both the polymer basics that are helpful to bring readers quickly up-to-speed if they are not familiar with a particular area of plastics processing and the recent developments that enable practitioners to discover which options best fit their requirements. New chapters added specifically cover polyamides, polyimides, and polyesters. Hot topics such as 3-D printing and smart plastics are also included, giving plastics engineers the information they need to take these embryonic technologies and deploy them in their own work. With the increasing demands for lightness and fuel economy in the automotive industry (not least due to CAFÉ standards), plastics will soon be used even further in vehicles. A new chapter has been added to cover the technology trends in this area, and the book has been substantially updated to reflect advancements in technology, regulations, and the commercialization of plastics in various areas. Recycling of plastics has been thoroughly revised to reflect ongoing developments in sustainability of plastics. Extrusion processing is constantly progressing, as have the elastomeric materials, fillers, and additives which are available. Throughout the book, the focus is on the engineering aspects of producing and using plastics. The properties of plastics are explained, along with techniques for testing, measuring, enhancing, and analyzing them. Practical introductions to both core topics and new developments make this work equally valuable for newly qualified plastics engineers seeking the practical rules-of-thumb they don't teach you in school and experienced practitioners evaluating new technologies or getting up-to-speed in a new field. Presents an authoritative source of practical advice for engineers, providing guidance from experts that will lead to cost savings and process improvements Ideal introduction for both new engineers and experienced practitioners entering a new field or evaluating a new technology Updated to include the latest technology, including 3D Printing, smart polymers, and thorough coverage of biopolymers and biodegradable plastics
