Raw material availability: In our warehouse we stock coils and bars in approximately 4000 different types, differentiating in specifications, 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 flexibility: 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:
+ State-of-the-art CNC cold forming of springs , using very high tensile strength, alloyed, oil-tempered spring materials up to 19 mm wire diameter; above 19 mm and up to 25 mm wire diameter, using our pre-hardened patented cold-drawn wire.
+ CNC Cold forming of springs up to 32 mm wire diameter, using annealed materials (for example 50 CrV4) in coils, heat-treated after winding.
+ Hot forming of coil springs up to 55 mm bar diameter (bar length max. 8.30 m)
+ 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 fixation of rubber bus hings on stabilizer bars
+ Zinc phosphating with subsequent powder coating (polyester | epoxy resin) or EPD 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 finished goods. This includes Eibach standard suspension- and industrial products as well as custom spec springs for call-off-orders.
