Technologies & manufacturing processes

We have exactly the right machine for every individual chipless metal-forming technology.

The shape your metal needs. The grain pattern found on the workpiece remains intact on our machines, while the mechanical strength of the material increases. Thanks to chipless machining, materials efficiency is much higher than in chip-removing processes, while the number of working operations is, generally, lower. But with maximum possible surface quality and tight tolerances.

Our core technologies for manufacturing processes of metal-forming technology:

Spinning
Shear forming
Necking-in (Reducing)
Flow forming
Hub forming
Profiling

Flow forming
In flow forming, a blank is rolled into an elongated shape by applying powerful forming rollers. The interior of the blank takes on the required contour, matching the tool mandrel, while the exterior exhibits a smooth surface. Capable, for example, of creating internally toothed gearing components, plate carriers, clutch components, and also wheels and wheel discs. › to machine overview
Spinning
A spinning roller deforms a preform rotating on a spin forming chuck into a rotationally symmetrical hollow body in a number of stages. The spin forming process scores with its flexibility. Shape changes can be accomplished quickly and at low cost. Despite cheap materials, the end product is exceptionally strong, thanks to cold hardening. Can be used, for example, for gearing components, pots, vessel heads, inlet rings, car hubs. › to machine overview
Hub forming
Where others perform cost-intensive turning and milling operations, we produce hubs in near-net shape for belt pulleys and gearing components in a single operation. This process, patented by ourselves, improves materials properties by means of cold hardening and permits one-piece design of the component with hub and part in the same material. There is no further need for welding or brazing, and the finished component has a longer service-life. › to machine overview
Shear forming
Shear forming is a special variant of spin forming and is used for tapered or conical shapes with a shear angle of > 18°. It is notable for especially rapid forming with changing wall thickness. › to machine overview
Necking-in
Gas cylinders for the automotive industry, fire extinguishers and breathing air cylinders are produced by means of necking-in. The diameter of a tube is reduced stage-by-stage until the base or the neck of a gas cylinder has been created. Wall thickness can be increased by a multiple in the necked-in area. This assures dependable gas tightness. › to machine overview
Profiling
A number of profiling rollers acting sequentially are pressed radially against the rotating workpiece. The workpiece takes on its external contour step-by-step. This mode of forming is especially suitable for the production of both simple and more complex geometries for belt pulleys with or without hubs. › to machine overview
