Follower Slides and Pressure Dies
Some jobs require a tool that holds the tube against the bend die under pressure applied by the bending machine at the line of tangency during the rotary-draw bending process, thus creating the point of bend. Originally the pressure die was a static die block that once clamped into position at the line of tangency did not move forward as the bend die rotated.
Traveling pressure dies, also called follower pressure dies, can reduce galling and marking of the tube by alleviating some drag during bending. By traveling at bend speed it can also reduce wall thinning on the out side of the tube. Some benders are equipped with boost or pressure die assist.
In Australia we manufacture complete tube bending and end forming tool sets to give our customer the best quality tools and turnaround times.
