The fully-automated manufacture of tension springs is another special domain of our production. Using numerous coiling machines, we can produce tension springs with a wire diameter of up to 7.5 mm in large series for the household appliance industry and the automotive industry. Both the thermal treatment and the shot-peening of the tension springs are incorporated into this production sector. The tension springs with wire diameters of 8 mm and larger are manufactured on the coiling machines, and eyelets are attached on article-specific special facilities. In many cases we complete the tension springs manufactured here with screw-in pieces made of plastic, cast iron or other metals. The completion of tension spring packages and the design of tension springs with high durability are our particular strength.
