This book was released on 2012-12-06 with total page 1139 pages. Available in PDF, EPUB and Kindle. Book excerpt: I am pleased to present the Fifth Edition of the Plastics Engineering Handbook. Last published in 1976, this version of the standard industry reference on plastics processing incorporates the numerous revisions and additions necessitated by 14 years of activity in a dynamic industry. At that last printing, then-SPI President Ralph L. Harding, Jr. anticipated that plastics pro duction would top 26 billion pounds in 1976 (up from 1.25 billion in 1947, when the First Edition of this book was issued). As I write, plastics production in the United States had reached almost 60 billion pounds annually. Indeed, the story of the U.S. plastics industry always has been one of phenomenal growth and unparalleled innovation. While these factors make compilation of a book such as this difficult, they also make it necessary. Thus I acknowledge all those who worked to gather and relate the information included in this 1991 edition and thank them for the effort it took to make the Plastics Engineering Handbook a definitive source and invaluable tool for our industry.

Book excerpt: PLASTIC MOLDING AN INTRODUCTION TO THE MATERIALS, EQUIPMENT AND METHODS USED IN THE FABRICATION OP PLASTIC PRODUCTS BY LOUIS F. RAHM Assistant Professor of Mechanical Engineering, Piinccton Inirersity FIRST EDITION FOURTH IMPRESSION McGRAW-HILL BOOK COMPANY, INC. NEW YORK AND LONDON 1933 PREFACE The art of forming objects in molds is ages old, embracing, as it does, the casting of metals, the blowing of glass, and the shaping of clay subsequently finished by baking. Although industries founded on this knowledge have persisted for centuries with little change in method or equipment, the molding of plastics, being dependent upon a machine age, is a relatively new-born industry. Founded on the molding of natural plastics, this industry showed little development before the intro duction of synthetic materials. These newer plastics, almost unlimited in supply and having in many cases desirable properties not found in natural materials, have opened up new fields of application for molded products. The most remarkable development has come about in the manufacture of precise parts suitable for electrical insu lation and mechanical uses. In these fields particularly, the phenomenal growth of the industry during the past twenty years has been due to the class of synthetic materials known as thermosetting plastics. In writing this book the author has attempted to present a general view of the methods and equipment used in the industry, in the interest of the manufacturer, the user of molded products, and the general reader. Particular stress on the molding of thermosetting plastics may be justified by the present importance of such materials and the probability that future plastics will be handledwith substantially the same methods and equip ment. In regard to the materials discussed, in view of the volumes available on this phase of the subject, viii PREFACE detailed chemical data have been considered unwarranted in a text of this scope. For much detailed information and for the generous loan of illustrative material the author wishes to acknowl edge the important contributions of Mr. Charles F. Burroughs and Mr. Walter E. Rahm, of the Burroughs Engineering Company. Other contributions are acknowledged as they occur throughout the book. Louis F. RAHM. PRINCETON, NEW JERSEY, Xcptcinbrr, 1033.

Download or read book The Complete Technology Book on Plastic Extrusion Moulding And Mould Designs written by NIIR Board of Consultants and Engineers and published by ASIA PACIFIC BUSINESS PRESS Inc.. This book was released on 2006-10-01 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plastics extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weather stripping, fence, deck railing, window frames, adhesive tape and wire insulation. There are fundamentally two different methods of extruding film, namely, below extrusion and slit die extrusion. The design and operation of the extruder up to the die is the same for both methods. The moulding process is one of the most important plastic processing operations. It is an important commercial process whereby a resinous polymeric compound is converted into useful finished articles. The origin of this process is dates back about a century to the invention of a plunger type machine. The mould has its own importance, which give the required shapes of the products. The vast growth of injection moulding is reflected dramatically in many types and sizes of equipment available today. Plastic moulding especially thermoplastic items may be produced by compression moulding methods, but since they are soft at the temperature involved, it is necessary to cool down the mould before they may be ejected. Injection moulding differs from compression moulding is that the plastic material is rendered fluid in a separate chamber or barrel, outside the mould is then forced into the mould cavity by external pressure. Plastic technology is one of the most vigorous manufacturing branches, characterised by new raw materials, changing requirements, and continuous development in processing methods. The injection moulding machines manufacturers plays an important part in the creation of injection moulding technology, process control, to essential mechanical engineering. Even though design is a specialized phase in engineering field, in tool and mould engineering it is totally divided into two wings as product design and tool and die design. This book basically deals with transport phenomena in polymer films, reinforcements for thermosets, miscellaneous thermoset processes, injection molding, blow molding, extrusion, basic principles of injection moulding, correct injection speed is necessary for filling the mould, plastic melt should not suffer degradation, the mould must be controlled for better quality product, logical consideration of moulding profile and material is important than standard setting guide lines, economical setting of the machine, proper maintenance of machine;, safety operations., preliminary checking for moulding, material, component, mould, machine, injection moulding technique, the various type of injection moulding machines, specifications, platen mounting of moulds, locating spigots, mould clamping, etc. The book covers manufacturing processes of extruded and moulded products with the various mould designs.

Available in PDF, EPUB and Kindle. Book excerpt: This book is for the industrial designer interested in the applications of plastics in products and industry. It explains how different plastics are processed, and it contains extensive examples of common and unusual plastic components and products with an explanation of how they are manufactured. Every year, more products are being replaced or augmented by the same product made from plastic, and this trend has resulted in much debate about the effectiveness of plastic replacements. Today's plastics can be designed to operate in all weather conditions and chemical surroundings. They can be economically produced for short run part production or readily adapted to high quantity production, and they can be cut, glued, tapped, or machined by traditional methods to suit design needs. Explains how to choose the best processing method, what fastening or joining methods can be used, and how to use the characteristics of a plastic to judge its suitability for an application. Covers all major contemporary molding processes. Discusses, in detail, important topics such as surface finish and special effects.
