Adhering to our motto—“Dedicated to Production, Responsible to the End”—we leverage prime Foshan logistics for swift delivery to domestic ports and global destinations.
Every production batch undergoes a rigorous 4-stage testing protocol to eliminate blade flutter, dynamic imbalance, and motor strain.
100% piece-by-piece testing on high-speed dual-plane dynamic balancing machines. Verified to ISO 1940 / ISO G2.5 balance grade.
Coordinate Measuring Machine (CMM) and optical profile projectors measure blade attack angle, root radius, and center bore concentricity.
Spin-tested at 150% rated RPM in an enclosed containment chamber for 30 minutes to verify structural integrity under extreme centrifugal load.
Charpy impact tests and free-drop evaluations on plastic impellers to ensure zero brittle cracking during logistics transport and assembly.
Feedback from fan distributors, assembly factories, and appliance brands sourcing metal and plastic fan blades for residential, commercial, and industrial fan applications.
“We purchase several sizes of replacement fan blades for pedestal, wall-mounted, and industrial fans. The biggest improvement has been consistency between batches. Blade diameter, hub size, mounting holes, and blade pitch remain stable, so our distributors receive parts that fit the intended fan models without additional adjustment.”
Fan Parts Distributor
“Blade balance used to be one of the main causes of vibration on our pedestal fan assembly line. After switching to Yayi fan blades, the blade weight, pitch angle, hub fit, and mounting dimensions became much more consistent. This reduced balancing adjustments during assembly and helped us maintain smoother operation at higher fan speeds.”
Electric Fan Manufacturer
“For our new fan platform, airflow and noise performance depended heavily on the blade geometry. Yayi helped us adjust the blade pitch, curvature, hub structure, and material selection during sampling. The final molded fan blade delivered smoother airflow, lower vibration, and consistent appearance across mass-production batches.”

Key commercial details covering MOQs, sample lead times, custom mold tooling, and international export packing.
For standard catalog blades (such as 18"–30" aluminum 3-blade or standard 16" 5-blade plastic), MOQ is 300–500 PCS. For custom colors or custom shaft diameters with existing molds, MOQ is 1,000 PCS. New custom tooling requires an initial production batch of 3,000 PCS (negotiable for trial orders).
Yes! We provide free catalog samples (1-2 pieces) for motor fitment, dynamic balance checking, and wind tunnel performance verification. The customer only covers international express courier freight (DHL/FedEx/UPS). Samples are dispatched within 24–48 hours.
Custom injection molds or progressive stamping dies typically take 12 to 18 business days from final 3D CAD drawing approval to first article inspection (FAI) sample delivery. Mold tooling fees are 100% refundable once annual order volumes reach agreed threshold quantities.
Standard order lead time is 7 to 12 working days for catalog fan blades. For peak summer production seasons or large container loads (20GP / 40HQ), lead times are typically 15 to 20 days. Urgent emergency air-freight batches can be fast-tracked upon request.
Aluminum blades are stacked with protective EPE foam separation pads and encased in reinforced 5-ply export master cartons with inner corner protectors. Plastic blades are packaged in custom blister nests to maintain blade pitch curvature and prevent pressure warping during long ocean voyages.
Yes, our 5,000㎡ plant includes all 3 core workshops: Fan Stem CNC Processing, Pipe Bending Processing, and Blade Processing, as well as complete assembly lines for finished commercial & industrial floor fans under your own brand.
