Two-Blade Metal Propeller

Featuring a symmetrical two-blade layout with a central cylindrical hub, this component is designed for fluid propulsion or mixing applications in compact mechanical systems. The blades exhibit a smooth, curved airfoil profile optimized for efficient torque transmission and flow dynamics, while the central bore provides a secure interface for mounting onto motor shafts or drive axles.

Manufacturing precision focuses on maintaining strict balance and concentricity between the blade tips and the hub axis to minimize vibration during high-speed rotation. The transition from the hub to the blade root requires careful machining to eliminate stress concentrations, and surface finish is critical to reduce drag and prevent cavitation erosion in liquid environments. Deburring and edge smoothing are essential steps to ensure safe handling and consistent aerodynamic or hydrodynamic performance.

Dongguan Kangsile Precision Technology leverages CNC turn-mill machining centers to produce these complex rotary parts with high dimensional consistency. Supported by IATF16949 and ISO 9001 certifications, the facility utilizes automated optical inspection and 3D contour measurement to verify blade symmetry, hub diameter tolerances, and surface integrity. This capability supports reliable production for industries such as drones, small-scale pumps, and consumer appliances requiring customized metal impellers or propellers.
