This book provides a simplified and practical approach to designing with plastics that funda-
mentally relates to the load, temperature, time, and environment subjected to a product. It
will provide the basic behaviors in what to consider when designing plastic products to meet
performance and cost requirements. Important aspects are presented such as understanding
the advantages of different shapes and how they influence designs. Information is concise,
comprehensive, and practical.
Review includes designing with plastics based on material and process behaviors. As de-
signing with any materials (plastic, steel, aluminum, wood, etc.) it is important to know their
behaviors in order to maximize product performance-to-cost efficiency. Examples of many
different designed products are reviewed. They range from toys to medical devices to cars to
boats to underwater devices to containers to springs to pipes to buildings to aircraft to space-
craft. The reader’s product to be designed can directly or indirectly be related to product
design reviews in the book.
Important are behaviors associated and interrelated with plastic materials (thermoplastics,
thermosets, elastomers, reinforced plastics, etc.) and fabricating processes (extrusion, injec-
tion molding, blow molding, forming, foaming, rotational molding, etc.). They are presented
so that the technical or non-technical reader can readily understand the interrelationships.
This type of basic information has been reviewed for many centuries with different types
of materials and more recently (in just over a century) with plastics. Recognize the de-
sign basics and/or fundamentals remain the same. Their interpretation and applicability
improves with time. It is like saying 2+2=4 for the many past centuries. Now we can
say it with a computer where in the recent past we used an abacus, adding machine, slide
It has been prepared with the awareness that its usefulness will depend on its simplicity
and its ability to provide esse
