The forming of bends using press brake tooling involves drawing the material into a die. As the material draws over the radii of the die some amount of abrasion to the material is bound to occur. In many cases the finished part will be used in a setting where cosmetics are important. Consequently, eliminating or at least minimizing the abrasion at the source saves a costly secondary operation.
Specific Press Brake Dies' no-mar urethane die film is economical and convenient. Available in various sizes x 100' long roll, different thickness' and strength durometer. Our White No-Mar urethane die film is .015" thick and available in 4" & 6" widths. Our Blue No-Mar urethane die film is .022" thick, also in 4" & 6" widths, is of a more durable durometer and has been tested to last 3 times as long as the white.
Simply cut a length long enough to cover the working area of the die and tape it in place. Material to be formed is the laid on top of the die film and bending proceeds. Our urethane die film prevents the part from coming in contact with the die therefore eliminating any marks. Being extremely durable the Die Cover Film will perform for numerous parts before having to be replaced with a new length.
