Surface RTM (S-RTM)

The newly developed surface resin transfer molding process enables cost-effective manufacturing of paintable fiber-reinforced visible components for vehicle manufacturing for series applications. That saves on time-consuming rework, which can amount to up to 60% of the costs per component.


  • Premium quality paintable surface for CFRP external automotive components
  • Combination of high-performance lightweight components with high-quality surface finishing

Core features

  • Flow-coating of surface RTM component surface with a polyurethane layer directly in the cavity
  • Emergence of paintable parts without additional intermediate steps
  • Savings up to 60% per component because time-consuming post-mold processing is no longer necessary
