Fan blades
Transparent and colored blades for stand fans, desk fans and air circulators. Blade count and size follow your design.
Plastic fan blade and blower wheel manufacturing, dynamically balanced before shipment
We manufacture injection molded fan blades, turbo fans and cooling fan components for home appliances. Mold development, injection molding and dynamic balancing testing all take place in one factory, so your blades run smooth and quiet.
Products
Fan blades and cooling components
We produce rotating and cooling plastic parts to your design and specifications, in both transparent and opaque materials.
Turbo fans & blower wheels
Multi-blade blower wheels and turbo fans for dehumidifiers, air purifiers and other appliances.
Housings & related parts
Housings, covers and structural parts for fans and small appliances, produced alongside the blades.
Dynamic Balancing
Dynamic balancing testing
Even a slight uneven weight distribution makes a spinning blade vibrate and hum, and over time it wears out bearings and motors. Dynamic balancing testing catches this before the blades leave our factory.
How we test
The blade is mounted on a computerized balancing machine and spun at speed. The machine measures how much unbalance there is and at which angle it occurs. These two readings tell us whether the blade meets specification and guide any correction.
+11.4 g·mmUnbalance: the size of the weight deviation
295°Angle: where on the blade it occurs
(Readings shown are from an actual test screen.)
Why it matters
For the end product, blade balance directly affects the noise and vibration users notice. Our fan blade quality and performance have earned the recognition of a Japanese premium appliance brand.

FAQ
Frequently asked questions
Can you develop a new fan blade from our design?
Yes. We can start from your concept or drawings, carry out structural review, mold development and trials, and move to mass production once approved.
Do you balance-test the fan blades?
Yes. We have computerized dynamic balancing equipment. Test methods and sampling rates are agreed with you based on the product specification and your quality requirements.
Can you also make housings or handle assembly?
Yes. Beyond blades we produce housings and related parts, and coordinate printing, assembly, packaging and shipping for one-stop manufacturing.
