High-pressure mixing head LFI

for polyurethane

Fibers and PU in Composite material The LFI-PU (long-fiber injection polyurethane) process is used in the production of high-strength, lightweight parts. *Versatile application *Wetting the fibers with the reaction mix *Fiber quantity and length can be configured based on requirements *Flow-optimized geometry of the cleaning piston Chopping glass fiber rovings *Cutting unit with cutter roller and pressure roller *Service-friendly: optimum accessibility with easy cutter roller replacement *Adjustable fiber quantity and length Mixing PU components *High-pressure counterflow injection: Components are shot into a mixing chamber at high speeds where the speed energy is converted into mixing energy. Wetting glass fibers *The flow-oriented geometry of the cleaning piston generates a hollow, hose-shaped material flow and ensures optimum wetting of the shortened glass fibers.
