A reduction in product cost through implementation of more economical materials and a reduction in process steps in the fabrication of an automated door system is the primary motive for a MQP in conjunction with Stanley Works, Inc. Stanley has also expressed a desire for color-through materials due to their intrinsic capability to undergo less cosmetic deterioration when deformed when compared to surface paints used on existing aluminum parts. After reviewing available alternates, several varieties of plastics were procured and evaluated for their capacity to meet and exceed the established minimum physical specifications. Component redesign in Pro/Engineer and finite element analysis enabled a theoretical prediction of performance under load in conjunction with experimental results. These results factored with economic considerations of material and process costs provided insights for the best,suited alternative to aluminum for this application.
