The third edition of this well-received book provides a comprehensive account of the full range of dies used for the extrusion of plastics and rubber, incorporating all the recent significant developments and innovations in the field of extrusion and die design. The distinctive features of the various types of dies are described in detail; there is also advice on die configuration, die heating, and the possibilities and limitations of computer-aided design as applied to extrusion dies. Fundamentals and computational procedures are clearly outlined, making prior knowledge of the subject unnecessary.

From the Preface: “...It may be the dream of an extrusion die designer to process all of the materials, processing, and geometical data of the final product with a computer and end up with a fully designed flow channel which facilitates the optimum flow distribution. In studying this book, the reader will realize that finite element analysis is a key to fulfilling this dream, but the proper description of the viscoelastic properties of the extruded materials is still a challenge for rheologists and engineers. Nevertheless, significant steps have been made in this direction. For viscous flow, that goal has almost been reached. Therefore, a new chapter on optimization of extrusion die performance with computers was integrated into this third edition...”

Target Audience: Plastics engineers involved with extrusion operations, as well as students interested in this technology.
