Controltec – precise monitoring of individual pressing processes

Controltec – precise monitoring of
individual pressing processes

A fastening has to reliably maintain its specified properties. For example, car
manufacturers ensure that it does so with a high repeatability rate by making use
of self-clinching systems. The accompanying monitoring technology records and
monitors the correctness of the required parameters.
