I am trying to vac form Lexan .007" and .020" thick with limited success.
I keep hearing about wave length, what does this have to do with the type of plastic one forms?
I am using 22ga nichrome coiled wire, not sure what effect if any the ga has has on Lexan.
How far above the lexan should the elements be?
At present it takes 20 seconds to heat the .007" Lexan to a droop.
All help appreciated
