1. Automotive Industry (Core Applications): Engine hood panels, intake manifolds, radiator water chambers, water pump housings, throttle body components, chassis brackets, rearview mirror frames, windshield wiper mounts, and small transmission gears (oil-resistant, high-temperature-resistant, and hydrolysis-resistant).
2. Electronics and Electrical Equipment: High-voltage connector bases, circuit breaker bases, relay housings, power coil frames, internal structural components of charging stations, high-power switch housings; V0-rated flame-retardant grades are used for power distribution insulation components.
3. Power Tools & General Machinery: Handheld drill/angle grinder housings, internal gears for impact drills, hydraulic pump bodies, bearing housings, sprockets, small-to-medium-sized drive gears, and load-bearing housings for instruments and meters.
4. Other Industries: Load-bearing brackets for high-end fitness equipment, bicycle pedals, pressure-bearing hardware for bathroom fixtures, gears for office equipment, and small structural brackets for drones.
Optimal balance of performance and cost: Strength far exceeds GF20, while the price is lower than high-glass-fiber-content materials such as GF35/40, making it the top choice for mass-producing high-strength components;
Low shrinkage and high precision: A 30% glass-fiber reinforcement structure suppresses thermal expansion and contraction, enabling controlled assembly tolerances for precision snap-fit and multi-cavity components;
Comprehensive range of modified grades: Available in three major custom grades—hydrolysis-resistant (suitable for automotive cooling systems), V0 flame-retardant (high-voltage electrical applications), and -35°C low-temperature impact-modified;
Wide molding compatibility: Flow properties superior to high-glass-fiber grades, ensuring smooth mold filling for complex structures and thin-walled large parts, resulting in high first-pass yield.
Drying: Dehumidifying drying at 95–110°C for 4–6 hours, with a moisture content of <0.12%, to prevent silver streaks and bubbles;
Barrel temperature: 265–290°C; nozzle temperature: 270–280°C;
Mold temperature: 85–100°C, to reduce fiber protrusion and improve product surface finish and dimensional accuracy.
