Contour-etched parts - precision springs

With progressive miniaturization precision springs are exposed to constantly increasing loads. Stamped springs can develop hairline cracks due to the mechanical tension inherent in the manufacturing process. Very complex precision springs can therefore no longer be manufactured this way - they break. In contrast, the special advantages offered by etching technology are ... - the type of technique, due to the fact that etching does not produce any type of microstructure change or mechanical strain. - the time-saving (from 24h) and cost-efficient prototype realization of complex precision springs.
