How do you ensure the precision required for high-RPM stability?

We maintain a tolerance of ±0.005mm on the center bore using precision jig boring. This ensures a perfect slip-fit on motor shafts, eliminating the high-frequency vibration and "propeller tracking" errors that can occur with looser tolerances.

Can you sign an NDA before I send my CAD files?

Yes. We understand that propeller hub geometry is often proprietary to your drone’s propulsion efficiency. We regularly sign Non-Disclosure Agreements and handle all 3D models (STEP/IGES) within a secure, internal environment to protect your IP.

What materials do you recommend for high-torque applications?

For most professional drones, we recommend 7075-T6 Aluminum due to its superior fatigue strength. For heavy-lift or extreme environment drones, we offer Grade 5 Titanium, providing a higher strength-to-weight ratio and better heat resistance near the motor.

What is the turnaround for custom propeller hub prototypes?

Our rapid-response cell can deliver finished propeller hub prototypes in 4-7 days. This includes CNC machining and your choice of surface treatment, allowing you to move from design to flight testing within a single week.

How do you handle surface treatment without affecting tolerances?

We calibrate our machining to account for the 5-10 micron buildup of Type III Hard Anodizing. This ensures that after the coating is applied for corrosion and wear resistance, your critical bore dimensions remain exactly within spec.

Can you support small-batch production for fleet testing?

Yes. We specialize in small-batch production (10–500 units) as well as mass production. This allows you to scale your order as you move from Alpha testing to final fleet deployment without needing to switch manufacturers.
