Silicon profile manufacturing systems

Silicon extrusion systems in KraussMaffei Berstorff quality

For the extrusion of solid silicon rubber, KraussMaffei Berstorff provides complete systems for manufacturing profiles and hoses.The design engineering and manufacturing of these systems demands a high degree of materials expertise and manufacturing quality. In order to achieve the highest output when processing solid silicone rubbers, the KraussMaffei Berstorff extruders are equipped with an innovative cooling system. The temperature of the rubber thus stays reliably below the response temperature of the catalyst.

System configuration
