In the LFI (Long Fiber Injection) process, endless fiber from a roving is chopped to length in a cutter. A blower then separates the filaments. Immediately after the cutter, the fibers are wetted with the PU mixture from the mixing head.
Your benefits
First-class surfaces through simple combinations of methods (painting directly in the mold, thermoforming film, PVC film)
High component stability at simultaneously low component weight by using high fiber volumes, fillers or paper honeycomb
Variable fiber lengths 12.5 - 100 mm and fiber volumes up to 50%
Significant weight saving compared to SMC
High degree of automation with short cycle times
Moderate mold and system costs due to low clamping forces
Integration of loaders directly into the mold
Applications
Engine hood
Radiator grill for utility vehicle
Engine hood for combine harvester
Bus rear panel
