Manufacturing Processes & Capabilities

• Thin-Profile Large-Diameter Tooling & Runout Control: Covers M0.2 to M1.5 modules for large-diameter, thin-web gear designs; balanced gating and mold flow control strictly minimize axial face runout and radial pitch-circle runout.
• High Concentricity Bore Molding: Accurately forms center shaft bores and locating interfaces with tight perpendicularity and concentricity relative to the pitch circle, eliminating rotational wobble at high rotor speeds.

Features & Advantages

• High Impact Toughness & Extreme Load Resistance: Engineered for 3D aerobatic maneuvers and rapid collective pitch changes; POM and engineered nylon deliver exceptional tooth shear strength and elasticity to absorb sudden torque spikes without tooth breakage.
• Lightweight Topology & Low Rotational Inertia: Incorporates optimized weight-reduction cutouts with structural reinforcement ribs, minimizing rotational inertia for faster throttle and pitch response.
• Smooth Transmission, Low Noise & Self-Lubrication: Spur profiles maximize power efficiency, while helical profiles increase contact ratios to suppress high-speed meshing whine; inherent self-lubricating properties ensure long-lasting wear resistance under continuous flight cycles.
