Compression springs are produced on modern CNC machines with 100% control of length, automatic length adjustment and elimination of unsuitable springs.

Production batches range from one piece to large-scale production.

We mostly produce springs based on customer drawings, but we can also advise you with development of new springs and help you come up with the best solution.

At the customer’s request we can equip each shipment with a measurement sheet containing the required data (F1, F2, cp, cpk…)

We can also draw up a sustainability test for the springs (fatigue test).

Wire diameter: from 0.15 to 4.0 mm

Spring shape: cylindrical, conical, double conical and special shapes

Materials: patented spring wires (EN 10270-1), oil-hardened spring wires (EN 10270-2), stainless spring wires (EN10270-3), zinc-coated spring wires, conducting wires (CuSn) etc.

The list of materials can be seen here.

Additional treatment: spring ends grinding, prestressing, shot peening, deburring etc.

Surface treatment: phosphatizing, bluing, zinc-coating, nickel-coating, passivation, powder-coating, KTL painting, application of special anti-corrosion or anti-slip coating etc.
