Plastics Extrusion Technology Handbook

Plastics Extrusion Technology Handbook

Offering complete and in-depth data and information on plastics extrusion, this practical handbook presents the technology of the subject rather than the theory. Presents an overview of extrusion technology as applied to the operation of extrusion systems and the design of tooling and equipment for use in the process. Provides basic technical information on the behavior of polymer and plastics materials in the extrusion process. Contains tool descriptions that provide a basis for the analysis of existing product lines as examples for the design of new systems. Includes illustrations of and background material on control systems for the extruder and extrusion process. Fundamentals of the Extrusion Process. Extruder Design, Construction and Operation. Extrusion Dies for Specific Product Lines. Controlling the Extrusion Process. Heat Transfer and Heat Content Considerations. Downstream Equipment and Auxiliary Units for Extrusion Lines. Coextrusion and Dual-Extrusion Technology. Extrusion of Cellular Plastics Products. Extrusion System Design and Integration. On-Line and Computer Control of the Extrusion Process. Plant Design and Operations. Extrusion Products and Processes. Glossary. Index.

Extrusion

Why is it important to get to equilibrium and how long does it take? Are there problems running polypropylene profiles on a single screw extruder? Does the job involve compounding color concentrates on a corotating twin screw extruder? This unique reference work is designed to aid operators, engineers, and managers in quickly answering such practical day-to-day questions in extrusion processing. This comprehensive volume is divided into 7 Parts. It contains detailed reference data on such important operating conditions as temperatures, start-up procedures, shear rates, pressure drops, and safety. This reference is a practical guide to extrusion bringing together both the equipment and materials processing aspects. It provides basic and advanced topics about the thermoplastics processing in the extruder, for reference and training. Parts 1 û 3, emphasize the fundamentals, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders. Parts 4 û 7 treat advanced topics including troubleshooting, auxiliary equipment, and coextrusion for operators, engineers, and managers. Extensive applications in Part 7 cover such contemporary areas as compounding, blown film, extrusion blow molding, coating, foam, and reprocessing. Each chapter includes review topics.
