About us
Mommer Metall- und Kunststofftechnik GmbH is a traditional, independent family business.
On 1st of June 1924 the partners Mathias Bildstein, Kaspar Lück and Peter Mommer founded the lead and tin casting foundry Bildstein, Mommer & Co, which in the following decades became known worldwide under the memorable name BIMOCO.
In 1973, Faensen, a manufacturer of closures and packaging products for the pharmaceutical industry, was integrated into our company. This created the preconditions for the continuous expansion of the product range. From then on, more than 80 million plastic articles were produced annually. In the meantime, our plastic production has been rounded off with our own articles such as battery covers or plastic seals.
The company name was changed to Mommer Metall- und Kunststofftechnik GmbH in 1997.
2025
The year 2025 had its ups and downs. Economic conditions, a further increase in the CO₂ tax, US tariffs, and finally the expansion of the Major Accident Hazard Regulation presented us with several challenges. Ultimately, however, we were able to overcome all of these challenges. We are optimistic about the future.
Our goal for 2026 is to convert our heating system to a green solution. The heating system should ultimately be CO₂-neutral.
