Whether working on product design or process optimization, engineers need a multitude of polymer property values. This book provides a quick reference on basic design data for resins, machines, parts, and processes, and shows how to apply these data to solve practical problems. Numerous examples are given to illustrate the appropriate applications of the data presented. Readers can carry out calculations using a handheld calculator.
