Processing is step 4, near the end of a finished product’s road, but pro-
cessing considerations have been present since Chap. 2, “Products and
Design.” Process selection is often made according to a product’s configu-
ration or design. When the process is selected, there are important deci-
sions to be made. This chapter provides background for complex and
critical decisions when one is selecting processes for engineering plastics
and other thermoplastics.
