Design Features That Influence Performance

Abstract

In Chapters 3 through 5,7, and 8 in particular some of the design problems of plastics were discussed. This chapter provides more detail on this important subject. Even though some of the analyses here will pertain to a specific process, many will relate to other processes, so it is best to review them all. Also, most of the characteristics of plastics that detract from their effectiveness refer to injection molding and provide guidelines for all the processes. Although it is not actually the product designer’s job to do so, the designer should have some idea of where problems can develop, based on how a mold or die is designed and manufactured [1, 2, 5–14, 21–32, 40–42, 45–46, 50, 55–68, 166, 208, 225, 253, 409, 478, 498, 564–70, 593, 637, 674, 807–15].
