Tools For Bending Pressure Die
Pressure Dies for benders with pressure die assist can benefit from grit blast or carbide spray tube grooves. This allows for more advancing force without slippage. Even serrated tube grooves can be used for automotive or for rough surfaced pipe. Length of pressure die equals the arc length of largest bend die + 2 x O.D. or minimum length required to mount on bender. For longer tool life, pressure dies can be machined to allow either end to be located at tangent. Pressure dies with worn, slick or oversized tube grooves prolong set-up time and allow wrinkles and excessive collapsed bends.
