Material - Springs, stamped and bent parts, 3D wire bending parts

Technical springs are products of wire material, which we use to torsion springs, bent wire parts, compression springs, Handle tension springs and stamped bent parts and be used as kinematic or functionally relevant components.

Therefore, we use materials from suppliers and producers to which we have long-standing, trusting relationships and their qualities for spring production meet the highest standards.
