• Dies with Rollers

    Increase in wear resistance through rollers to see a decrease in bending marks and press force.

  • Adjustable Dies

    Our adjustable dies adjust for bending up to 30 degrees, so fewer tool exchanges are needed.

  • BLACKFIRE

    Rolleri BLACKFIRE is a particular coating of  your tools which defines itself by its  increased corrosion resistance and special design.

Material

We use raw material only from qualified suppliers and in accordance with the HIGHEST INTERNATIONAL STANDARDS. Guaranteeing high resilience and tensile strength.

Material Type Mechanical resistance of the material
and the tool body
Hardness of the material and the tool body Hardness of the operating surfaces
after induction hardening
42CrMo4 900-1150 N/mm2 29,1 – 36,9 HRC 54 – 60 HRC
C45 560-710 N/mm2 12 – 15,5 HRC 54 – 60 HRC

  • Specifications for the maximum press force kN/m are indicated as such, 1 t = 10 kN.

Solutions for heavy tasks

Going Beyond Quality

The bending of materials with extreme high resistance, (Hardox, Weldox, etc.), has  developed into an important task.

The Heavy Duty tools of Rolleri are built and finished for these challenges.

Tools that have a press force up to 4000 kN/m, off er you many production possibility.

Our many years of experience in the area of special and heavy duty tooling, along with our own developing department, guarantee you functional and economic solutions in the bending sector.

From the compatible tang to the punch onto the compatible die; we manufacture  everything in our own production facilities.

Take advantage of the direct contact to the manufacturer and the benefits which come along with it.
