LFT mould (Long Fiber Thermoplastics)

LFT is bulk molding material that feature continuous fiber filaments running the full length of the pellet allowing these materials to exhibit simultaneous improvements in strength, stiffness, and impact resistance over a wide temperature range.

Meanwhile, D-LFT (Direct-long fiber thermoplastics) is available for injection or compression molding. Most D-LFT systems, for injection or compression molding systems, feed glass roving (or other fiber) into a twin-screw extruder (TSE), where it is chopped by the screws as it is mixed with molten polymer and additives that have been metered in separately. To improve surface finish, some systems use knives to prechop the roving prior to entrance into the TSE. This method generally yields a shorter fiber, while the direct roving feed produces longer fibers and yields parts with higher structural performance. Each approach uses different and specialized screw designs.

What’s the advantage of D-LFT mold?

– Reduced production costs by the elimination of semi-finished products and logistical effort
– Increased production flexibility
- D-LFTstrand with variable thickness for optimized mold filling

D-LFT mold is mostly used in Automotive.
