© Copyright Quest Industries Ltd While the actual duration depends on the complexity of the design, and the approval process, the typical development timeline is: 6-12 weeks for tool build, 1-3 weeks for inspected samples, 1-3 weeks for finished part evaluation (total 8-18 weeks). | | | | | How long does it take to go from design to production? Typically, production part wall thickness can vary from nominal by +/- 20%, and linear dimensions by a basic +/- .030" plus .005" per linear inch of the dimension in question. Additionally, a tooling tolerance of +/- .030" plus .0025" per linear inch of dimension must be considered when molds are being built. Tighter production tolerances may be achieved. Our development engineers are available to discuss important features, and how well they can be controlled. What kind of tolerances can rotomolding hold?
