Large-Volume Profiles for Hydraulic Steelwork, Profiles Supplied by the Metre, Frames and Corner Joints

For technical applications, we develop, design, and manufacture functionally optimized rubber profiles. Our high-quality profile seals are used across industry, local authorities, and commerce, and are individually tailored to meet specific requirements.

A particular specialization lies in large-volume rubber profiles for hydraulic steelwork. Our hydraulic steelwork profiles are utilized, for example, in the field of sluices, locks, and other hydraulic structures where reliable sealing, high resistance, and a long service life are critical.


Rubber Profiles for Hydraulic Steelwork

For application in hydraulic steelwork, we manufacture specialized large profiles for hydraulic structures in a wide variety of geometries and dimensions. The profiles can be delivered supplied by the metre and further processed in accordance with the respective installation scenarios.

Depending on the design and function, components such as flat profiles, angle profiles, or musical note seals are utilized. The selection of the suitable rubber material and the configuration of the profile are carried out to match the technical requirements of the respective application.

Particularly in the case of locks and hydraulic structures, sealing profiles must function reliably and permanently perform their role even under demanding conditions. Our rubber profiles are therefore specifically matched to the respective design and the intended area of application.


Large Profiles, Corner Joints and Ready-to-Install Frames

Alongside manufacturing profiles supplied by the metre, we offer the further processing into custom structural components. From our hydraulic steelwork profiles, we manufacture items including corner joints for profiles as well as complete, ready-to-install frames.

As a result, our customers receive not only individual rubber profiles but, upon request, fully fabricated sealing solutions prepared for installation. This facilitates assembly and enables a precision-fit implementation even for complex geometries.

Tailormade Solutions Through Reliable Processes

Extrusion Technology

The manufacturing of rubber profiles is carried out in several stages. Through extrusion, the compound is formed into accurately profiled semi-finished products as an intermediate stage. The rubber compound is plasticized within the extruder by the screw and profiled as it passes through the shaping die. Despite predominantly varying flow cross-sections, uniform flow behaviour must be achieved to ensure a straight discharge of the uncured profile from the die.

  • Free-flowing and dimensionally stable rubber compounds
  • Extruders with screw diameters of up to 120 mm and output capacities of up to 40 kg/h

Vulcanisation

Following extrusion, rubber profiles are vulcanised horizontally in an autoclave, suitable for various cross-sections and large-volume profiles. For tension-free installation in tight radii, specialized jigs and supporting profiles ensure the correct shape and sealing lip alignment during vulcanisation.

  • Straight profiles up to 40 m in length
  • Profile cross-sections up to 340 mm in width and 130 mm in height
  • Tight radii through the use of specialized jigs

Permanent Joints

Fully vulcanised profile strands, including those with differing cross-sections, are permanently joined using a compression moulding process in profiled, electrically heated tools. For this purpose, a customized rubber compound is injected under high pressure into the cavity of the corner and hot-vulcanised. According to technical drawings or specifications, we can also provide the products with perforations, chamfers, and notches.

  • Joining already vulcanised profiles
  • Permanent joints, even with differing profile cross-sections
  • Perforations, chamfers, and notches
