About AL Gummi + Kunststofftechnik
AL Gummi + Kunststofftechnik GmbH is a specialist in industrial rubber seals and elastomer products with complex geometries. The portfolio includes the extrusion of profiles – including demanding and large-volume cross-sections such as profiles, rings, frames and round cords – as well as the manufacture of molded articles including rubber molded parts, rubber-to-metal bonds, rubber composite parts and pigs (pipeline inspection gauges). Production covers large and medium volumes as well as the smallest series and individual custom-made products down to one-off items; molded articles are produced with series and batch traceability. Elastomer grades such as NR, NBR, HNBR, EPDM, CR, FKM, PU and silicone are processed in various hardness levels and color settings. Customers include mechanical and plant engineering, the chemical industry, automotive and electrical engineering, the food and beverage industry, hydraulic steel construction and pigging technology; deliveries are made throughout Europe. Since 2025 the company has been certified to ISO 9001.
