Our series for special hubs

Vertical rim pressing plus rim bending machine

We are the world’s only supplier that enables production of high-quality wheels for all-terrain vehicles, quad bikes, golf caddies and smaller steel hubs without the requirement of a rim roller. Our two VFD/VRB machines permit production of hubs without rim rollers, and the manufacture of small batches and trouble-free production of various hub geometries.

The unbeatable benefits:

  • Rim production without rim rolling line
  • Uncomplicated and fast small batch production starting from four wheels
  • Rapid changeover between a wide variety of rim shapes.

The machine pair VFD (Vertical Rim Pressing Machine) and VRB (Vertical Rim Bending Machine) can be built with various special equipment on request or equipped with our automation offers and SMART FORMING tools.
