Screw extruders are workhorses in the plastics industry — they are used to pump, mix, carry out chemical reactions, and devolatilize polymer systems. Screw Extrusion helps the reader obtain an understanding of the underlying principles of operation for screw extrusion equipment, thus aiding in the optimization of equipment and the achievement of enhanced production output. Most importantly, this book promotes a concise understanding of the processes governing extrusion, solid conveying, melting and metering. The contributions come from both industry and academia, producing a well-balanced presentation.

From the Preface: “...Screw extrusion machines used in industry have both simple rotating screws and screws which both rotate and reciprocate. Screw extrusion machines often contain multiple (usually two) screws rather than single screws, which may rotate in the same or opposite directions...Screw extrusion technology naturally divides into (i) the design and behavior of screw based machines, and (ii) post-screw processing including dies, take-up equipment and molds. This book is limited to the first of these areas...”

Target Audience: Chemical, mechanical, plant, process, and design engineers; plant, process, engineering, and maintenance managers; and other professionals concerned with screw extrusion.
