INDUSTRIAS BOSCH S.A.

Cylindrical pullback springs are made with coils close to each other. At both ends of a spring, eyelets are bent up or screwed in. There are many factors which may have an influence on the shape of a spring and an eyelet. We advise and help you to find a suitable spring.

Bent wire parts represent a separate part of our production range. Bent parts differ from springs such as extension springs, compression springs and wave springs in terms of how they are produced. This type of spring is not only processed with automated machinery, but also involves a considerable amount of special handling, which we perform using our range of state-of-the-art equipment. Precision production with our high-tech machinery: Our range of machinery with an in-house toolmaking workshop enables three-dimensional bent parts to be produced with a wide variety of forms and with specialised finishes applied to the ends. Our range of machining processes includes: Bevelling, embossing, thread cutting, thread rolling, turning and milling. For bent wire parts, both CNC bending and mould-based bending are possible as production solutions.We process wire thicknesses of 0.20 to 8.00mm.Tool-based: 0.50 to 8.00 mm. Coating of part surfaces: Oiling, Vibratory finishing, Galvanisation.

We supply the European and international market with spring steel wire for temperable springs from our Iserlohn-Kalthof plant in sizes ranging from 7.0 mm to 40.0 mm
