Our company

We have been a partner for plant and scale engineering for over 42 years, developing flexible components for the bulk goods industry. Our years of experience with the distribution of free-flowing and highly adhesive bulk goods enable us to develop the right kind of supply and discharge systems for your plants and to manufacture them in our facility. Originating from a small business for rubber products, we have constantly expanded our expertise and now employ over 30 employees in production, 3D design, and service. Now we can develop and supply globally customized products, spare parts and engineering services for plant engineering and bulk goods handling in companies from a wide variety of sectors.

Our Know-How

Our endeavor is to adapt our solutions optimally to each customer, whereby each of our products is flexibly conceived from the first sketch to the final design. With our diverse expertise in the processing of elastomers, we have frequently developed particularly effective and unique solutions, with many of our flexible products having become standard in the bulk goods industry. We grapple with each problem intensively and develop an individual, innovative solution for each system. Of course, our contacts offer you help and assistance throughout the entire process.


Our Team

Our team of experienced experts provide you with competent advice at every step for your customized solution. To do so, we can fall back on years of experience handling difficult bulk goods and offer you comprehensive service extending from the first sketch to the final design and offering you the most effective solution possible. At every step, we offer you help and advice with our competent expertise and provide you with a flexible final product. Most of our products are handcrafted on our own premises so we can remain, just like our products, flexible at all times.


Our Location

After 25 years in our old plant on Siegburgerstrasse 43 in Königswinter-Oberpleis, we moved in 2006 to Humboltstrasse 9 in the industrial park Am Krahfeld. Since then, a modern office building for design and administration and a production hall housing our manual rubber production, final assembly, and the metal workshop have stood on a 4000 square meter plot. The direct connection to A3 highway (Siebengebirge exit) and local proximity to the Cologne-Bonn airport distinguish our location and offer easy accessibility for our customers.

Original FIX-STEIMEL® spare parts


As the original manufacturer of products for FIX STEIMEL® plants, we have developed many products that are still present in many plants and have specifically adapted them to the respective technical requirements. With having taken over all technical documentation of the FIX-STEIMEL® company in the area of weighing and bagging technology and due to our consistent archiving of original templates and work instructions, we can provide you with a matching and correctly designed spare part for your plant in the original quality.
