1978 First orders from abroad, in cooperation with injection moulding machine manufacturers. First tools for the manufacture of closure components. First participation in a trade fair outside Germany.

1975 Wilfried's son Reiner starts his apprenticeship as a toolmaker within the family business. In 1985, he becomes a master toolmaker and a shareholder in the firm, which has since gone on to become a private limited company with a customer base that extends across Germany. Its core expertise: the manufacture of injection moulding tools for technical components for the electrical and automotive industries.

"Quality means to satisfy the customer”.

Last but not least:

WIRO is responsible for setting milestones in tool manufacture, e.g. through the development of new kinds of cooling and demoulding systems, the use of special steels and coatings, guaranteed cycle times, full documentation and a unique, comprehensive service.

Between 80% and 90% of WIRO's production now goes to export, serving customers in over 73 countries, in 9 of which the company maintains a sales office.

Since 1985, the number of people employed at WIRO's head office in Olpe has remained constant, at between 30 and 35.
