A method for forming a polycarbonate panel, the method comprising the steps of cutting a flat polycarbonate panel to the desired final dimensions, inserting the panel between the two portions of a die, forming the panel by means of compression between the two portions of the die, overbending the panel between 1-12 degrees to achieve a predetermined angle of bends in the panel and repeating these steps until the panel is fully corrugated. The method further includes the steps of heating the die and/or the panel by means of an electric strip temperature of between 100-110 degrees Fahrenheit. An apparatus is also provided for forming a polycarbonate panel. The apparatus includes a die where the die includes a first portion and a second portion. The die being automatically adjustable in height and width. The first portion and the second portion movable with respect to each other and the first portion and the second portion operable to compress and overbend a panel to form a bend in the panel.
