tolerances for polyurethane foam
tolerances for polyurethane foam
(OP)
I'm looking for rough tolerance estimates for a polyurethane foam part.
It's about 11" long by 4" wide by 1", and I'm looking for a tolerance on the 11" dimension.
0.050? 0.060? I'm not looking for an authoritative answer ( I know it varies), but more a collection of gut feels. I am developing a concept and just need a ballpark.

RE: tolerances for polyurethane foam
Did you perhaps want to ask about the expected variation associated with some specific process?

"What is the tightest tolerance I should specify to avoid a price increase from the supplier?"
Check with suppliers application/sales people, or to put it into terms that ensure it gets translated from the "front end guys" to the "pricing guys":
Ask for quotes at 0.025, 0.050, 0.075, 0.100" tolerances, up to the max you can accept.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
