oil canning and chill markd or vaccume trap?
i am having some problems with a sign face. the plastic is clear 3/16" polycarbonite with back graphics 3m colered vinyl. the mold is made out of aluminum the head is an 1" deep draw and the outer pan is 2 3/8" deep. the problem i am having im not sure what to call it, or how to fix it. if you look at the face from the side it is bowed out the compitetions face is nice and flat. there are also waves in the part of the face to the left of the head? is this oil canning? and last there is an almost semi circle line that goes from the right top of his head around to his right shoulder is this vaccume trap? i am geting ready to tear this mold apart and redo it due to the head embossment is the wrong size i could use some imput and ideas into what the problems are and what my solutions might be. thanks rwolf:confused: i will post more pics in a response.
