Every manufacturer has different tolerances.
I hope this helps

Yes indeed. It might be better stated that "every manufacturer has different specifications"
The truth of the matter is in the manufacturing and production process there are many details that have to be correct for it all to come together in the end as a finished product that can perform to design specs.
Let's take the example of a wall assembly for a travel trailer. First we would go to the adhesive manufacturer and explain to them what the materials are that we are bonding. They would make a recommendation of what adhesive to use, based on design parameters. Once we have decided on the materials and proper adhesive, the good folks at the adhesive manufacturer would tell us what surface prep, clamping pressure, procedure, time and temperature for correct use of the product.
Guess what ? At the end of the day here....the correct process may involve.....vacuum bonding. Imagine that....a process that is widely used in many industries can very well be the correct method.
Making statements like "vacuum bonding is a EPIC FAIL" is not a correct statement. One needs to know more about what the underlying details are in the parts being manufactured.
Edit: by the way, in case anybody cares, the correct answer to pressure applied in a vacuum bonding scenario is "atmospheric pressure", which is right at 14 pounds per sq inch.
