Of course products need to be envisioned before they can be produced, but a failing of many manufacturing engineers is that of not approaching their design duties from a variety of perspectives, including manufacturing. This paper describes and analyzes a circuit board assembly line, assesses the evolution of the manufacturing of three-prong electrical plugs and speculates on the type of plastic that could be used in manufacturing processes following the path of the processes in which steel is produced. Bibliography lists 9 sources. A 15 page paper discussing the role of polymers in controlled-release drug delivery systems. Includes six illustrations and graphs.
