In the early years, tools and devices were manufactured for external companies as an evening operation.

In order to meet the demands of the ever more numerous customers, stamped parts were soon manufactured and supplied.

This resulted in the first functional division between tool-making department and stamping plant.

In the following years, in terms of stamped parts, the company increasingly specialised in the processing of electrical steel, whereby DIN parts for transformers, engine sheets and magnetic plates were manufactured.

The key customers in the early years were the big radio equipment manufacturers such as Grundig, Saba and Blaupunkt.
