If a fab shop is bending tube with a rotary draw machine and seeing wrinkles on the inside radius, it might need a wiper die.

A longstanding problem in tube bender tooling setup is tooling misalignment, which leads to scrapped tube (wasted material) and requires additional setup time to align the tooling (wasted time). Interlock tooling takes advantage of the bend die’s interlock opening, integrating the various tooling elements and keeping them aligned.
