The minimum or maximum cross-sectional wall thickness of any part depends heavily on the overall part size and design. For example, a wall thickness of 0.010″ may be possible if it is localized, but not if it spans the entire length of a 4″ long part. Typically, the optimum wall thickness is 0.040″ to 0.120″, again related to the overall size of the part. Minimizing wall thickness also reduces the material content of the part and its cost.
