Besides our longlasting experience in stamping and turning, SCHNORR now also offers technology of fineblanking, manufacturing know-how of distortion of critical disc springs and an additional product group – the wave spring.
Two strong brands combine their energies mutually to be able to offer the full product range of both from one concern, thereby enabling us to better fulfil the continually rising market demands, now and in the future.
