PA66 Polyamide Pellets are widely used to manufacture high-strength, heat-resistant, and dimensionally stable components across demanding industrial applications, including:
Automotive Industry (Core Applications): Heavy-duty engine compartment brackets, turbocharger piping fittings, intake manifolds, water pump housings, radiator water chambers, load-bearing transmission components, BMS housings for new energy battery packs, chassis suspension control arms, and high-voltage connector bases (oil-resistant, high-temperature-resistant, and hydrolysis-resistant).
High-Voltage Electronics and Electrical Equipment: High-power circuit breaker bases, internal load-bearing brackets for charging stations, industrial variable-frequency drive housings, high-voltage terminal block bases, and high-power motor coil frames (V0 flame-retardant grade used for power distribution insulation components).
Industrial Machinery & Power Tools: Heavy-duty angle grinder/hammer drill housings, industrial hydraulic pump valve bodies, heavy-duty bearing housings, precision transmission gears, pump impellers, lightweight structural components for robotic arms, and agricultural machinery transmission brackets.
Other Applications: Load-bearing brackets for heavy-duty fitness equipment, high-end bicycle pedals/cranks, small components for construction machinery, drone landing gear structural components, and high-pressure valve bodies for bathroom fixtures.
Ultra-high rigidity and creep resistance: A dense 40% glass-fiber reinforcement skeleton ensures dimensional stability under long-term loads, making it the top choice for heavy-duty load-bearing components;
The preferred choice for metal lightweighting: Strength comparable to die-cast aluminum alloys, yet lighter in weight, with injection molding efficiency surpassing die casting;
Comprehensive range of modified grades: Hydrolysis-resistant grades suitable for automotive cooling circuits; V0 flame-retardant grades for high-voltage power distribution; cold-resistant grades that do not crack at -35°C;
Controllable molding: Flow properties superior to GF50; smooth filling during injection molding of thick-walled, multi-cavity, heavy-duty parts; significantly fewer fiber floats compared to high-glass-fiber grades.
Drying: Dehumidifying drying at 105–120°C for 4–6 hours, with a moisture content of <0.10%, to prevent silver streaks and bubbles;
Barrel temperature: Barrel 265–295°C, nozzle 275–290°C;
Mold Temperature: 90–110°C to optimize surface finish, suppress fiber protrusion, and stabilize product dimensional accuracy.
