CompanyAbout DIAMANT

We haven’t been what we are today just since yesterday: 130 years of success and experience – the vital history of a healthy company.


To this day, DIAMANT Metallplastic formulates, develops and produces exclusively in Germany – still with the customer-oriented thinking of a family-run company, whose responsibility for people and the environment is just as easily recognised as its uncompromising commitment to quality and performance.

DIAMANT's German-made products are dispatched to the world's industrial centres via a worldwide distribution network of over 40 foreign agencies. Apart from production, the business fields consulting and application have been expanded in recent years and the company has become a full-service partner, for product development, production and product application.
DIAMANT Metallplastic: "Quality is when the customer comes back – not the product".

Historisches Prospekt DIAMANT-Kitte


Reconstruction of the factory that burned out in August 1943 in the new industrial area at Breite Straße 118.
Unfortunately, there are no more pictures from this period.


The two sons Robert and Alfred Schulz take over the factory. Robert Schulz senior dies in 1944.

Robert Schulz, Drogen-Handlung


Production of first irons and polishing putties for the foundry industry. The realignment is evidence of expertise and foresight. Because from the knowledge of the production problems of foundry products and chemical processes, Robert Schulz unerringly deduces the growing need for metal repair putties. Only a short time later, leading foundries in Germany used the first repair putties formulated by him as "casting cosmetics". The foundation for the company's success, which has lasted for more than 130 years, has been laid.

Robert Schulz


Robert Schulz founds the first drugstore in Rheydt at Hauptstrasse 20. This develops into the "Rheydter paint, spatula and putty factory".
