Explore our high-performance glass-fiber-reinforced polymer (GFRP) pellets designed for precision injection molding across demanding global applications.
In modern high-stress engineering environments, the paradigm shift from traditional die-cast metals (aluminum, zinc, magnesium) to lightweight, ultra-rigid thermoplastic composites is accelerating. Long Glass Fibre Reinforced Polyamide (LGF-PA) represents the pinnacle of structural material evolution.
Unlike standard Short Glass Fiber (SGF) compounds—where fibers shatter into microscopic lengths (<0.8mm) during extrusion—our specialized melt-impregnation pultrusion manufacturing technology ensures that continuous glass filaments remain intact throughout the polymer matrix pellet (typically 10mm to 25mm in length).
Key Takeaway for Design Engineers: The retention of a 3D skeletal fiber network inside the injection-molded cavity provides unprecedented creep resistance, energy absorption, dynamic fatigue endurance, and dimensional stability across temperatures ranging from -40°C to +150°C.

We go beyond material exporting by offering holistic engineering consulting to optimize customer injection molding operations worldwide:
From New Energy Vehicles (NEVs) to smart industrial tools, LGF-Polyamide polymer granules provide lightweight strength everywhere.
Crucial for increasing range in Electric Vehicles by cutting structural mass. Applications include front-end module carriers, brake pedal brackets, battery enclosure trays, structural door modules, and under-the-hood engine covers subject to high vibration.
Replacing aluminum motor housings with LGF-PA66 provides superior impact energy absorption during drop tests, lower hand-arm vibration for operators, and electrical insulation properties for heavy-duty rotary hammers and lawn mowers.
LGF-PA12 and LGF-PA66 granules are widely utilized in water treatment filter press frames, high-pressure pump impellers, industrial valves, and pneumatic actuators requiring dimensional stability in constant contact with moisture or chemicals.
Continuous infrastructure investment and transparent customer quality inspection protocols.
Global automotive component clients visited our Jurong manufacturing facility for a rigorous quality inspection of PA6 and PA66 long GFRP (Glass-Fiber-Reinforced-Polymer) granules. The inspection verified continuous fiber dispersion, cut length uniformity, and lab tensile testing accuracy. The delegation expressed full confidence in our quality control system.
Our factory successfully installed and commissioned a next-generation automated melt-impregnation pultrusion line. The expanded line boosts our annual output capacity significantly while tightening tolerance controls on fiber content percentage, satisfying growing global export orders for high-temperature nylon formulations.
