Polestar Metal Excellence in Action: The High-Performance UAV Landing Gear

• Challenge: A leading drone manufacturer required a critical, load-bearing landing gear component that was ultra-lightweight for extended flight time, yet extremely strong to withstand repeated hard landings. Tight tolerances were mandatory for seamless assembly.

• Our Solution: Polestar Metal engineers recommended Precision CNC Machining from 7075-T6 Aluminum for its optimal strength-to-weight ratio.

• Process: Utilized advanced 5-axis CNC machining to create a complex, one-piece design that eliminated weak points from welding or fasteners.

• Finishing: Parts underwent Type III Hard Coat Anodizing for superior surface hardness, wear resistance, and corrosion protection in outdoor environments.

• Result: The delivered components reduced weight by 22%compared to the previous design while increasing load capacity by 15%. The flawless precision ensured 100% assembly compatibility, enabling our client to accelerate their production line and enhance their product’s market competitiveness.
