Production 生产

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.
