Die Design for Extrusion of Plastic Tubes and Pipes
A Practical Guide
Format: PDF, ePUB
E-Book: € 79,99
'Die Design for Extrusion of Plastic Tubes and Pipes' covers this topic from a uniquely practical perspective. The content draws on the author's over 50 years of experience in the plastics processing industry, most recently as head of the successful extrusion die manufacturing company he established in 1995. His approach is oriented toward solving production problems at the design stage using computer aided techniques for design and simulation of the plastic flow.
The book provides a step-by-step guide to extrusion die design, with worked examples to illustrate problem solving. It is shown how important melt flow variables (e.g., pressure drop, shear stress, shear rate, temperature variations, and distribution variations, etc.) of key materials are determined using FEM software. The detailed drawings of complete dies for various applications that are provided constitute a rare and valuable resource. Both mono- and multilayer pipes are covered.
Using the proven methods and examples from this book, the reader is well-equipped to understand dies for successful manufacture of tubes and pipes of many types.
