Plastic products manufacturing is one of the largest industrial activities in the US. Today's marketplace is very fast paced with many products having a much shorter life than ever before. While injection molding is the most common process for economically producing complex designs in large quantities, a large initial monetary investment is required to develop appropriate tooling, which may not be appropriate for applications with low production quantities
Component cost and lead-time models are developed for an electrical enclosure from extensive industry data potentially manufactured by a variety of low to medium volume manufacturing processes including direct fabrication, fused deposition modeling, selective laser sintering, vacuum casting, CNC machining, and injection molding with soft prototype tooling, and hard tooling. The viability of each process is compared with respect to the manufacturing cost and lead time for specific production quantities of one, ten, one hundred, one thousand, and ten thousand. Process selection varies greatly with the desired production quantity and cost/lead time sensitivity. The results indicate that the average cost per enclosure assembly is highly sensitive to the production quantity, varying in range from US $0.35 to US $135.80 per enclosure, while the lead time to manufacture the enclosure and the required tooling/programming could vary from 2 days to 49 days with a marginal production time varying from 67 minutes to 0.5 minutes
