Special parts

 

  • Copper coils
    Various designs and dimensions; wires with round or square cross-sections; various coatings with stripped ends; from prototype to large batch series.

  • Conveyor spirals
    Used as rock drills, in medical technology or for supply processes (dosing, weighing and mixing). Manufacturing length of up to 1,200 mm; diameter of up to 130 mm.

  • Endless coils
    They are needed where a continuous process without interrupts is required, e.g. for the plastics industry or to reinforce cables of 500 mm to 1,000 m in length.

Special parts

 

  • Tolerance rings
    These parts are installed in steering columns and are used as an anti-theft device. They act as a safety clutch that lets the steering column slip at a certain torque when locked. We manufacture tolerance rings with narrower torque ranges than prescribed in the directive. In each particular case they are adapted to the respective construction; therefore, they are developed and manufactured to meet the customer’s specific requirements.

  • Torsion bars
    These parts are usually manufactured with a circular bar cross-section. Specially shaped bar ends facilitate clean clamping and application of a specific torque. Compared to the torsion bar, they are thicker and have a square or hexagonal cut or are serrated.
