Wet molding

Recycled fiber mats can be used in the wet molding process. The manufacturing process for the fiber mats can reuse materials such as the waste product from cutting fiber mats made of continuous fibers. This involves binding the individual fibers and forming them into mats again. However, the fibers are no longer aligned, but instead statically distributed. The flow resistance would be extremely high for impregnation in a closed mold, which is why the resin is added outside of the mold.


  • Lightweight components for challenging product specifications, approx. 50% lighter than steel
  • Can be fully-automated and is suitable for series production

Core features

  • Processing of recycling material
  • Lower clamping forces are sufficient for the presses due to the significantly lower cavity pressure
