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.

• Material width of up to 160 mm
• Provision of advice from the prototype to the mature series production part
• In-house prototype workshop
• In-house construction
• In-house tool manufacture

Punched parts

• Material thickness from 0.05 mm to 4 mm

Moulded sheet metal parts

• Material thickness from 0.05 mm to 4 mm

Flat spiral springs

• Material thickness from 0.2 mm to 1 mm
• Material width from 1.5 mm to 50 mm

Disc springs

• Punched, without subsequent chip removing process
• Different material qualities
• Material thickness from 0.2 mm to 1.25 mm (DIN 2093)
• Material thickness from 1.5 mm to 5 mm (not in accordance with DIN 2093)

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.
