• tight tolerances – very small pitch errors axial forming of splines possible also on thin walled tubular components• excellent surface quality, little roughness• block teeth and missing teeth possible• short cycle times (for example 5 seconds)• low tooling costs / high tooling performance (approx. 50.000 pcs. and greater)• cold formed part / possibility of taking advantage of hardness increase• homogenous internal stress distribution / little deformation during heat treatment
