Klappentext 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. In addition to a comprehensive revision to the overall handbook, an entirely new chapter on a new development--Computer-Aided Analysis--has also been added. "This is a great book."--INJECTION MOLDING Zusammenfassung Explains in plain terms why moldings shrink and warp. This book offers practical understanding to novices! and insights to readers already skilled in the art of injection molding and mold making. It contains the answers to common problems and detailed advice on how to control mold and post-mold shrinkage and warpage. Inhaltsverzeichnis 1. Introduction to Plastics Processing 2.
