GD&T Percentage tolerance
GD&T Percentage tolerance
(OP)
Hi everybody,
I have designed a plastic tank (12" x 12" x 18"), not square, with different embossing & pocket.
The manufacturer (Rotomolding process) have a capability tolerance of +/-2% for the outside shape and 5% for the planar surface. How I can transpose these tolerance on my 2D sheet?
Thanks for help!

RE: GD&T Percentage tolerance
The material of my recovery coolant tank is polyethylene HDPE, it must resist to high & low temperature.
After looked your reference, I am agree with the excessive tolerance of my supplier, I will communicate with him and discuss the competitor's tolerance.
Also, you have resolved my GD&T problem, I will inscribe on my 2D drawing a linear tolerance as I have seen; "linear dimensions by a basic +/- .030″ plus .005″ per linear inch".
Thank you very much for your help, I appreciate.
Have a great day.
