Fibro manufactures and supplies special spiral compression springs, steel springs and spring elements for punching and metal forming technologies as well as diaphragm springs and spring shape elements.
The spring type used depends on the individual requirements. They have four load groups that can be used in either tool manufacture, engineering or in the construction of jigs and fixtures.
The permissible value of the shear stress and the spring oscillating stress differential depends on the spring material used. FIBRO special spiral compression springs are manufactured from 50CrV4. The specially milled profile allows a high level of alternating and continuous loads and is ready for operations at working temperatures of up to 250°C.
