Fusion without Steam – Innovative & Future-oriented

Circular Economy ■ Energy savings of up to 90 % ■ Fusion from inside to outside for perfect core fusion ■ Best solution for new particle foams with high temperature resistance -fusion temperature up to 250 °C ■ Perfect for high densities, e.g. EPS with densities above 200 g/l ■ No expensive media installation necessary; steam generation plants and cooling tower installations with water basin are not required ■ High proportion of recycled material e.g. > 70 % in EPS moulded parts Fields of Applications Due to their high dynamic and static shock resistance, their low weight and their strong insulating...

The basis for processing the material beads is a dielectric alternating field that causes polar molecule chains to oscillate. This generates friction and thus heat. The beads are heated by excitation with high voltage. Steamless Processing with Electrical Energy The innovative Kurtz process using radio waves is ideal for foaming materials with a polar molecular structure. Non-polar materials such as EPS can be processed using suitable additives. Product Benefits ■ Remarkably better fusion ■ Reduced moisture absorption ■ Very low residual moisture in the moulded part ■ Notably lower shrinkage...

Simulation & Automation Possibilities Development and Handling According to Individual Requirements Complete Simulation A dielectric tool is required for the RF process. Kurtz is able to carry out reliable simulations for toolmaking. This means that optimizations can be implemented into the design even before the tool is manufactured. ■ Fast and cost-effective representation in virtual space ■ Results feed directly into further developments ■ Display of thermal behaviour and electromagnetic fields ■ Energy calculations ■ Optimized tool construction ■ Can be used for staff training and internal...
