Cylindrical parts

Cost-effective production of bushings, sleeves, head rest tubes and field rings.

As an alternative to expensive turned and deep-drawn parts, we manufacture bushings for pressing or injection into a plastic or metal housing using a cost-effective production process. Our technology allows us to meet tight tolerances at economical production costs.

Our capabilities:

  • Length of up to 110 mm
  • Wall thickness of 0.5 to 2 mm
  • Outside diameter: Up to 30 mm
  • Length tolerance to < 0.1 mm
  • Diameter tolerance to < 0.05 mm
  • Front face parallelism to < 0.05 mm
  • Gap open or closed
  • Insertion bevels available
  • Round or oval
  • Apertures / stamping

We manufacture field rings for small motors using a cost-effective production process to provide an alternative to material and cost-intensive turned and deep drawn parts.

Characteristics and properties:

  • High precision combined with high output
  • Can be manufactured from pre-coated raw material or raw steel with subsequent surface treatment
  • Reliable fastening by means of laser welding, resistance welding, caulking, clipping or clinching

Head support tubes for fixing headrests to the seat structure or as the axis of rotation of the headrest. Manufactured using a cost-effective, single-stage production process.

Our capabilities:

  • Length of up to 150 mm
  • Wall thickness up to 2.5 mm
  • Outside diameter: Up to 45 mm
  • Raw edge inside or outside available
  • Round, half-round and square standard shapes
