In the extrusion process the TPE pellets are poured into a hopper are heated in the barrel and turned into a melt by this heat and shear. A screw carries the melted plastic through a shaped die to produce continuous lengths of shapes with the same profile, which are then cooled by air or water. Our TPE compounds are easily extruded into single and complex profiles. They can also be co-extruded with other materials to yield a part with both rigid and soft components. They exhibit improved profile flexibility. The SEBS compounds, with their saturated intermediate blocks, are very stable against thermal degradation. On the other hand, the SBS compounds degrade if overheated or if a screw with excessively high compression ratio is used. The information below is intended as a general overview, settings may vary depending on the specific grade selected.

Space-saving in a vertical (e.g. for retrofitting) but also in a horizontal version, our extruders are available in many variations for your specific needs. For applications with larger throughputs, we have high-quality extruders with heat-separated feed zone cooling, which deliver a high-quality melt for the further process. We also offer coordinated screw designs for special materials such as PVC, PA, EVOH, E-PET or adhesive layers.

Molybdenum-hafnium carbide (MHC) is highly temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts. At higher temperatures, the producer recommends using MHC for full dies. The benefits to you for a long service life: — Optimum nondeformability and dimensional stability — Low tendency to crack in the case of edged profiles — High thermal stability — High thermal conductivity — Low thermal expansion — Good hot ductility — Very high recrystallization temperature Plansee supplies MHC components in disc form with or without drilled start hole.

The aluminium extrusion process uses a press to shape a hot aluminium billet by means of compression. The profiles resulting from the billet that flows through the die at a temperature of 500ºC are laid out, cooled and stretched on a roller bed, subsequently moving towards the saw where they are cut to the desired size.
