A simple plastic part cost estimator using Microsoft(R) Excel

This paper explains a relatively simple methodology for estimating the cost of injection molded parts and provide open access to a Microsoft(R) Excel workbook of spreadsheets which utilizes this methodology. The open architecture of the workbook allows part designers to understand the assumptions and sensitivities defining their parts cost. By providing a simple estimating tool to designers in industries that are not heavily penetrated by thermoplastic material usage, it is believed that better thermoplastic applications may be achieved
