About our ABS molds

When ABS molds are formed over a mold they will thin some as they are pulled over the mold. The thinning will be in the flange area of the mold; however, the top of the mold will be close to the thickness given. A mold that is made from 3/16” will not measure exactly 3/16” at it’s flanges, and how thin it gets depends on the shape and depth of the mold. So that is why we state that our molds are made from a starting material thickness. So some of our mold flanges may measure less than the starting material thickness stated if measured at the flange, and there is not much that can be done to stop this. Some do use push frames to make flanges thicker, but this just pushes the thin spot towards the corners. If you are in this trade, you know molds will not measure exactly as the thickness listed, much like buying a 2” x 4” at your local hardware store, as they do not measure 2” x 4”. There is tons of information about this from manufacturers and schools that teach this course. I have placed a link below if anyone would like to read more about this. If you have more questions, please ask before buying.
