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 and cost-efficient prototype realization of complex precision springs.
