Rubber profiles are produced endlessly by extrusion. For this purpose, the unvulcanized rubber mixture is plasticized in extruders and brought into the appropriate cross-sectional geometry by means of attached extrusion tools (mouthpieces) in the extrusion head of the system. The mouthpieces can be adapted as required to produce different profile cross-sections, so that the right geometry can be realized for every application. The profile is dimensionally stabilized by subsequent vulcanization. Vulcanization in a steam boiler or salt bath is used here, as well as hot air vulcanization, UHF production or IR shock vulcanization. Rubber profiles are used for protection or sealing in vehicle construction, the construction industry and general mechanical engineering, among others.
In the case of dynamically stressed profile seals, we calculate the necessary contact pressure forces and then adjust them specifically by means of hollow chambers or foam structures. The necessary overlap or the gasket stroke can be numerically optimized by means of FEM analysis. These special designs are supplemented by a wide range of standard profiles.
To improve the handling and to facilitate further processing, we offer various finishing options.
To simplify the assembly process, profiles can be equipped with simple, self-adhesive assembly aids. These cold-applied adhesive tapes serve, for example, as transport protection, but do not represent a permanent fastening. By using heat-activated adhesive systems, profiles can also be fixed or bonded permanently and process-safe if required. For example, pull-in grooves in various components can be dispensed with.
