In the case of foamed plastics, the FDU wide-slot nozzle is able to exploit some of its advantages particularly well. These include, above all, a significant reduction in component distortion with a simultaneous increase in the specific bending modulus. In addition, the cooling time and the cycle time are considerably reduced, as we have less shear or friction in the component. This also allows lower densities to be achieved.

All these advantages of FDU add to the consistent advantages of the foaming process.
