What Is PA6 LCF60? Key Technical Specifications
Chopped-fiber PA6 CF60 and short-fiber PA6 GF60 lose most fiber length inside the screw. LFT-G® PA6 LCF60 keeps it: polyamide 6 melt-impregnated with 60% long carbon fiber, as injection molding pellets whose fibers reach the mold as structure, not filler.

Long carbon fibers interlock into a 3D skeletal network that carries load, so parts resist vibration, impact and creep beyond short-fiber grades.

How PA6 LCF60 Is Made: Melt Impregnation
Unlike chopped-fiber compounds, these pellets are not extruded from premixed short fibers. Carbon fiber rovings are pulled through molten polyamide 6, wetted, then cut to pellet length, so every pellet carries full-length fiber.
Fiber Roving
Continuous carbon fiber bundles feed the line at controlled tension.
Melt Impregnation
Rovings pass through molten PA6; every filament is wetted by resin.
Pulling & Cooling
The impregnated strand is pulled and cooled into a solid rod.
Pelletizing
Rods are cut into pellets that keep the full fiber length.
Processing Guidelines & Customization Options
Dry pellets in a dehumidifying dryer before molding; wet polyamide 6 surfaces as splay marks, voids and lost strength. Run a low-shear screw, moderate back pressure and generous flow channels so fibers survive plasticizing. Choose wide sprue, fan or tab gates; avoid pin gates and hot-runner nozzles, which shear the network.
Exact settings are issued in the processing guide, supplied with the TDS on request, so trials run on verified settings, not estimates.
Standard supply is black; custom colors, pellet length and heat or UV stabilization are made to order. The PA6 LCF family (LCF20 to LCF60) steps stiffness up or down on one resin.
Applications & Metal Replacement Value
LCF60 earns its price where parts stay stiff under load at weights metal cannot reach.
Robotic Arms & Automation Links
Links cycle millions of times and punish every gram. The carbon skeleton carries cyclic loads without fatigue cracking and cuts motor torque.
Protective Helmets & Sports Guards
A helmet shell must spread one hard impact across its surface; the fiber network distributes that energy instead of concentrating it at the strike point.
Drone & UAV Airframes
Frames trade stiffness against flight time gram by gram. An LCF60 arm holds motor alignment under thrust and landing shocks, corrosion-free.
Automotive Structural Components
Brackets, carriers and seat structures take over work usually given to die-cast aluminum; the fiber network spreads bolt and crash loads, with ribs molded in.
Power Tool Housings
Tool shells absorb drops, vibration and motor heat daily; LCF60 gives a rigid backbone that protects gears and resists cracks at screw bosses.
Manufacturing Scale & International Certifications
Produced in Xiamen by a long fiber specialist since 2009, every LFT-G® lot is tested before release; its certificate of analysis travels with the shipment.

Frequently Asked Questions
Q1: Can PA6 LCF60 replace die-cast aluminum parts?
For many brackets and housings, yes. Send the drawing and load case; our engineers confirm feasibility against the datasheet.
Q2: Which gate types protect long carbon fibers?
Wide sprue, fan and tab gates keep shear low. Avoid pin gates and hot runners; we review tool designs on request.
Q3: Is trial material available before bulk orders?
Yes. Trial samples ship with the full TDS and processing guide, so trials are judged on verified data.
