Frequently Asked Questions

Q: What are the core advantages of PA66+GF (Glass Fiber Reinforced Nylon) compared to pure plastics (PC, ABS) or carbon fiber?

A:vs. Standard Plastics (PC/ABS):Standard plastics lack sufficient flexural modulus and easily undergo aeroelastic deformation under heavy loads and high-speed rotation, causing a sharp drop in lift and a spike in power consumption. PA66 modified with Glass Fiber (GF) dramatically increases flexural modulus and tensile strength, guaranteeing geometric stability of the airfoil at high speeds.
vs. Carbon Fiber:Although carbon fiber offers excellent rigidity, it is brittle with low impact resistance (susceptible to fracturing upon impact with crops or tree branches) and carries high production costs. PA66+GF offers the perfect balance of high rigidity, impact fatigue resistance, and exceptional cost-efficiency for mass production via injection molding—making it the ideal choice for industrial-grade drones.

Q: Glass fiber injection molding often suffers from "floating fibers" and surface whitening, affecting aesthetics and aerodynamics. How do you solve this?

A:Floating fiber is caused by flow speed differences between the glass fiber and resin, combined with rapid cooling at the mold walls.
Tooling Design:In the pre-production stage, we perform professional Moldflow analysis to optimize runner and gate designs, preventing melt shear separation when flowing through thin-walled blade sections.
Manufacturing Process:We utilize closed-loop precision injection molding machines paired with high-temperature, high-pressure mold temperature controllers to maintain intense heat on the mold surface. This forces the resin to instantly form a smooth, dense "resin-rich layer" against the mold wall, encapsulating the glass fiber inside. The resulting blades feature a mirror-smooth finish with zero floating fiber or whitening issues.

Q: Propellers are thin-walled, complex shapes. Adding glass fiber easily leads to warping due to uneven molecular orientation. How do you ensure flatness in mass production?

A:Glass fiber reinforced materials exhibit drastic differences in shrinkage rates parallel vs. perpendicular to the flow direction.
DFM Stage:We perform micron-level optimization on the wall thickness gradient from blade root to tip, structurally eliminating injection stress concentrations.
Production Stage:We apply a multi-stage packing pressure switching process to compensate for differential shrinkage. Combined with uniform conformal cooling channels inside the mold, both sides and edges cool synchronously. This minimizes thermal internal stress warping, ensuring rock-solid dimensional consistency across large-scale production runs.

Q: Drones have extreme dynamic balance requirements at high RPMs. Minute weight variations cause severe frame vibration and the "jello effect." What are your QC standards?

A:Dynamic balance is the lifeline of a propeller. Our quality control spans both static weight and dynamic balance:
Static Weight Control:A fully automated central feeding system ensures consistent raw material dryness, while precision injection machines precisely control shot size for every cycle.
Dynamic Balancing:Our production lines are equipped with specialized high-speed dynamic balancing testers. Every outgoing batch undergoes rigorous simulated full-speed testing to guarantee smooth motor performance, reduced power consumption, and zero vibration upon installation.
