Why Choose Our Die-Cast Aluminum Fan Blades?

1. Performance-Driven Design: We don't just cast shapes; we engineer aerodynamic components using simulation tools to meet or exceed your airflow and pressure specifications.

2. Weight & Strength Optimization: Aluminum die casting offers the best strength-to-weight ratio for dynamic rotating parts, improving efficiency and reducing load on motors.

3. Superior Consistency & Balance: The die-casting process ensures part-to-part uniformity, which is crucial for balancing. Our in-house balancing guarantees smooth operation.

4. Cost-Effective for Medium-High Volumes: For production runs from 5,000 to 500,000+ units, die casting provides an unbeatable cost per part for such complex geometries.

5. Full-Service Solution: From aerodynamic design and CFD, through tooling and precision casting, to balancing and final machining-we handle it all.

FAQ

Q: What is the main advantage of aluminum die-cast fan blades over plastic or stamped steel blades?
A: Aluminum die-cast blades offer a superior strength-to-weight ratio. They are significantly stronger and more durable than plastic blades, allowing for thinner, more efficient aerodynamic profiles. Compared to stamped steel, they are lighter (reducing rotational inertia and motor load) and can be cast into much more complex, optimized 3D shapes that are impossible to stamp.

Q: What aluminum alloys do you typically use and why?
A: We primarily use A380 and ADC12 (A383) alloys. They offer an excellent combination of:

Fluidity: Fills thin, complex mold sections easily.

Strength: Good mechanical properties for structural integrity.

Castability & Cost: Reliable and economical for high-volume production.

Corrosion Resistance: Suitable for most indoor and many outdoor environments. For specific needs, we can use A360 (better corrosion resistance) or other alloys.

Q: Can you produce very large diameter fan blades?
A: Yes. Our high-pressure die-casting machines can produce single-piece blades/impellers up to approximately 800mm in diameter. For larger diameters, we utilize segmental casting and assembly techniques, where the blade is cast in sections (e.g., hub and individual blades) and then precision-assembled and balanced.

Q: What is the minimum blade thickness you can achieve?
A: We can consistently achieve blade thicknesses as low as 1.2 mm at the trailing edge, thanks to our advanced vacuum-assisted die-casting process. This allows for lightweight, efficient designs.

Q: Can you reverse-engineer or copy an existing fan blade?
A: Yes, we offer reverse engineering services. By taking precise 3D scans of your existing part, we can create a CAD model and replicate its geometry and performance characteristics. We can also suggest improvements to the design or material during this process.

Q: What quality certifications do you hold?
A: We are ISO 9001:2015 certified. Our processes for automotive-related components are developed in line with IATF 16949 principles. We can provide Material Test Certificates (MTCs) for alloys and support PPAP (Production Part Approval Process) documentation for automotive customers.

Q: What information do you need to provide a quotation?
A: Please provide as much of the following as possible:

3D CAD file (STEP, IGS) of the blade OR performance specifications (diameter, # of blades, CFM, static pressure, RPM).

Annual volume estimate (for accurate pricing).

Target material/alloy.

Required balance grade (e.g., G6.3, G2.5).

Any special requirements (surface finish, special testing, certifications).

Q: What is your Minimum Order Quantity (MOQ)?
A: Due to the high cost of precision mold (tooling) manufacturing, our production MOQ typically starts at 5,000 pieces. However, we welcome prototype orders (via CNC machining) for quantities as low as 1-10 pieces for design validation.

Q: What are your typical lead times?
A:

Prototype (CNC Machined): 2-3 weeks.

Production Samples (from new mold): 10-12 weeks from order confirmation and final design approval.

Mass Production: 12-14 weeks for the first batch; lead times shorten for subsequent orders.

Q: What are your payment terms?
A: Standard terms are:

For Tooling/Mold: 50% deposit with order, 50% balance before sample shipment.

For Production Orders: 30% deposit with order, 70% balance before shipment.

Q: What is your payment term?
A: We provide kinds of payment terms such as L/C, T/T, Paypal, Escrow, etc.
