Polyurethane Casting Primer

Omitting complicated chemistry concepts, Polyurethane Casting Primer presents practical details on the casting of polyurethane products to assist readers in their daily work. It covers fundamental methods, explores hands-on design and production topics, and keeps theory to a minimum. The book fully explains casting and allied processes. Starting from a "bucket and paddle mix" open pour, postcuring machining, bonding, and painting, it discusses how to produce quality products continuously. The author describes the necessary precautions for maintaining the health and safety of workers. He covers the properties of polyurethane systems, the tests and results of polyurethanes commonly used in compression, and the correct grade and processing of polyurethanes for meeting customer requirements. He also reveals how to fix issues such as molding problems and premature end of life. The versatility of polyurethane enables a wide range of applications, from simple, noncritical parts to vital engineering products. This book guides manufacturers in designing and producing polyurethane products. Batch calculations are available for download at www.crcpress.com

Castable Polyurethane Elastomers is a practical guide to the production of castable polyurethane articles, from simple doorstops to complex items used in the military and nuclear industries. The book shows the progression from raw materials to prepolymer production, including the chemistry and functionality of the production processes. It provides a comprehensive look at various problem-solving and processing techniques, examining the selection of different types of systems on both the micro and macro levels. It also discusses curing and post-curing operations, conveying the importance of using the correct property for the application. Reorganized for better flow, this Second Edition: Describes new methods in the processing of castable polyurethanes Expands coverage of health and safety aspects Brings all standards up to date Castable Polyurethane Elastomers, Second Edition explains the production of polyurethane components, filling the gap between pure chemistry and trade information.

Currently, raw material suppliers are the sole providers of polyurethane processing information. In most cases, they give instruction only on how to mix products and do not always include an explanation of the accompanying logic as to why these recommendations are being made.

A hands-on guide to choosing and using old and new technologies for joining plastics and elastomers. Includes detailed discussions of over 25 techniques used to join plastics to themselves and to other materials. Advantages and disadvantages of each technique along with detailed discussions of applications are presented. A second section is organized by material and provides details of using different processes with over 50 generic families of plastics and how different techniques and operating parameters affect weld strength and other criteria. This book is an excellent reference and an invaluable resource for novice and expert alike in determining the best joining technique for their application and providing guidance in how to design and prepare for production.

This book is a valuable reference for the materials engineer, the manufacturing engineer, or the technician who wants a practical description of fabrication processes. Sheet metal fabrication processes are receiving greater attention and are more widely applied by the metalworking industries because of the savings in cost and material. This book compiles the proven theories and operations tested in industrial applications. Focus is on the non-chip-producing machine tools that shape metals by shearing, pressing and forming. New materials and advances in tooling are discussed, as well as the need for applied science in optimizing the operations for sheet metal fabrication processes. Examples of each of these forming processes are given, and the text also describes the mechanics of each process so that a logical decision can be made concerning the best operation for a specific result. The volume is divided into five sections each consisting of a series of chapters. The major sections cover fabricating presses, stamping and forming operations, plastics for tooling, structural shapes, and non-traditional machining. A section on definitions and terminology is also included.The book is profusely illustrated and indexed, making it easy to find references to specific forming topics. Written by an expert with 40 years of hands-on practical engineering experience, this Handbook contains the essential information you need on forming methods, machinery and the response of materials.
