PRODUCTION

• Raw material availability: in our warehouse we stock coils and bars in approximately 4000 different types, differentiating in specifi cations, dimensions, surface grades and similar. This extensive stock of raw materials ensures a premium disposability for prototypes and single
  pieces as well as for small, medium and large production runs.
• Quality and fl exibility: it is our top priority to combine highest quality with maximum flexibility.
• CNC- Manufacturing technology: the use of state-of-the-art CNC technology in the entire production allows to minimize set-up times,
  ensures highest precision, small tolerances and optimum surface quality.

Some significant production features:

• Hot forming of coil springs up to 55 mm bar diameter (bar length max. 8.30 m)
• Cold forming of springs from coil-material, heattreated after winding, going up to 32 mm wire diameter
• Use of pre-hardened wire (drawn | heat-treated) from 0.2 mm to 25 mm wire diameter
• State-of-the-art grinding- and production machinery through implementation of our own production knowledge
• Chamfering of spring ends (in- and outside) by robots and especially developed handling systems
• Internal tool- and gauge shop
• Improvement of the dynamic durability through state-of-the-art shot peening techniques including thermal- and stress peening
• Relaxation minimization through controlled heat-setting processes
• Economic in-house developed CNC bending technologies for stabilizer bars, made of prehardened solid or tubular material for small batch sizes and series, mostly used without additional tools
• Stabilizer end processing, using in house developed robot-supported systems
• Vulca-bonding process: especially designed by our engineers for the fi xation of rubber bus hings on stabilizer bars
• Zinc phosphating with subsequent powder coating (polyester | epoxy resin) or KTL as alternative Extensive range of colors available, including
  UV-resistant powders
• Product identification through pad-, ink-jet printing or laser marking
• For just-in-time- | just-in-sequence deliveries, compliance with call-off- and delivery plans as well as for the implementation of economical production batches, we offer an extensive, barcode-controlled warehouse for fi nished goods. This includes Eibach standard suspension- and industrial products as well as custom spec springs for call-off-orders.
