Wiper dies

The function of the Wiper Die lies in it's ability to mitigate crinkling on the inner radius of the tube bend and it is used primarily in tubes with relatively thin walls and smaller bend radii.

Due to the ever-growing requirements for shapes and especially with thinner and thinner walls, the wiper die is regularly used in almost all bending kits.
Just as with mandrels, the materials used in the production of the Wiper Die is very important (usually the same material as the mandrel and the wiper die) and also it's correct set-up.

Square back

This is a wiper die used for small series or one-off production and also for more complicated applications, where the important factor is the rigidity and stiffness of the wiper die.

Wiper die holder + Insert

This type of wiper die is made in two parts, with a holder and insert. This is mostly used in large scale production. The disadvantage of this is a lower stiffness compared to the squareback wiper die.
