In a very practical and down-to-earth way the author explains how quality in extrusion can be measured, controlled, and improved. In particular, he conveys an understanding of how extruders should be controlled and what good, closed-loop controls can accomplish. The author's approach and style clearly conveys that he has been involved in this field for many years and that he knows from experience what kind of problems an extrusion operator faces and how to successfully tackle these problems. This book is a helpful tool to improve and stabilize the extrusion process, thus facilitating a more profitable operation.
