1. 400ton die casting, high density, heavy duty. The wall with uniform thickness and no die surface porosity.
2. New material of Aluminum Alloy without inclusions.
| Material | aluminum alloy A380,A360.ADC12,Zinc alloy 3#zinc,5#zinc and 7#zinc,etc |
| Designs |
1.As per the customer's drawings 2.As per the customer's sample |
| Surface treatment |
1.As-Cast coated to achieve corrosion resistance.Cast parts are typically broken away from the casting sprue, leaving rough marks at the gate locations. Most castings will also have visible marks left by the ejector pins.Surface finish for as-cast zinc alloys is commonly 16-64 microinch Ra. |
|
2.Anodizing (Type II Or Type III)Aluminum is typically anodized. Type II anodizing creates a corrosion-resistant oxide finish. Parts can be anodized in different colors-clear, black, red and gold are most common. Type III is a thicker finish and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II. Anodized coatings are not electrically conductive. |
|
|
3.Powder Coating where powdered paint is electrostatically sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion resistant layer that is more durable than standard wet painting methods. A wide variety of colors are available to create the desired aesthetic. |

1. What are Fan Blades and Impellers?
A Fan Impeller (or rotor) is the rotating assembly within a fan or blower that moves air or gas. It consists of a hub and multiple attached blades. The blades are the airfoil-shaped components that create airflow by converting rotational energy into kinetic energy and pressure. We manufacture both individual replacement blades and complete, balanced impeller assemblies.
2. What types of fan blades/impellers do you produce?
We specialize in a wide range for various fan types and applications:
Centrifugal Fan Impellers: Forward-Curved (FC), Backward-Curved (BC), Backward-Inclined (BI), Radial (Paddle Wheel) blades.
Axial Fan Impellers: Propeller fans, Vane-axial fans, Tube-axial fans.
Mixed Flow Impellers.
HVAC Fan Wheels: For air handlers, furnaces, condensers.
Industrial Process Fans: For high-temperature, material handling, or corrosive fume applications.
Custom Designs: For OEM ventilation equipment.
3. How are fragile impellers packaged for shipping?
We use custom, protective packaging:
Individual cradling in foam or cardboard partitions within a strong cardboard box.
For large impellers: Custom wooden crates with internal bracing.
Clear marking of "Fragile" and "Do Not Stack".
4. How do I select the correct replacement blade or impeller?
For replacements, exact matching is crucial. Please provide:
OEM Part Number from the original fan manufacturer.
Detailed dimensions: Overall diameter (OD), bore size (ID), blade count, blade dimensions, hub design.
Clear photos from multiple angles, including any labels on the hub.
Fan Model Number and application.
For new designs, we need performance parameters (CFM, static pressure, RPM).
5. What is your manufacturing process?
We use advanced processes for precision and balance:
Stamping/Blanking: For simple, high-volume axial blades from sheet metal.
CNC Machining: For precision aluminum or plastic blades and hubs.
Die Casting: For complex aluminum hub shapes.
Fabrication & Welding: For large or heavy-duty steel centrifugal impellers.
Dynamic Balancing: Every impeller is dynamically balanced to ISO 1940 G6.3 grade or better (G2.5 for precision applications) to ensure smooth, vibration-free operation.
6. Can you balance an existing impeller or provide balancing services?
Yes. We have a fully equipped balancing workshop and can provide impeller rebalancing as a standalone service. Please send us your used impeller for assessment and repair.
7. What about coatings and surface treatments?
We apply finishes as needed for protection and performance:
Paint: Industrial-grade epoxy or polyester powder coating.
Plating: Chrome or nickel plating for wear resistance.
Anodizing: For aluminum parts (hard coat or decorative).
Passivation: For stainless steel to enhance corrosion resistance.
Special Coatings: Abrasion-resistant or anti-stick coatings for material handling fans.
8.How do I request a quote or engineering support?
For the most efficient response, please provide as much as possible:
OEM info (Part #, Drawings) OR Performance Specs (CFM, Pressure, RPM, Power).
Material and application environment.
Target quantity.
Any applicable industry standards (AMCA, ISO, etc.).
9. Can you reverse engineer a blade/impeller from a sample?
Absolutely. We specialize in reverse engineering for discontinued or custom parts. Send us your worn or broken sample, and we can measure, redesign, and manufacture a direct replacement, often with material or design improvements.
10. What is your MOQ (Minimum Order Quantity)?
Standard Replacement Parts: MOQ 50 pieces.
Custom/OEM Impeller Designs: MOQ 100 pieces (due to engineering and tooling setup).
High-Volume OEM: MOQ negotiable.
11. What is your production lead time?
Reverse Engineering & Samples: 20-30 working days.
Standard Production: 30-45 working days.
Large Custom OEM Projects: 60-90 days after design freeze.
12.Do you supply complete fans or just components?
We are primarily a component specialist. However, for OEM clients, we can supply complete fan assemblies, including motor mounting plates, housings (scrolls), and guards, sourced through our integrated supply
