Cast Fan Impeller – OEM Aluminum, Ductile Iron & Steel Impellers
Fan impellers are one of those parts where the casting has to be right the first time. Blade profile, balance and wall thickness all come out of the mold, and a rejected wheel costs more than a good mold. We cast impellers in aluminum, ductile iron and steel - from vehicle cooling-fan parts to industrial ventilation wheels - finished, machined and balanced to your drawing.
Materials & Casting Processes
| Material | Process | Best for |
|---|---|---|
| Aluminum alloy (A356-type, T6 available) | Die casting / precision casting | High-volume, thin-wall impellers with tight tolerances |
| Ductile iron, cast steel | Sand casting / lost foam casting | Large-diameter, high-strength industrial impellers |
| Stainless steel | Precision casting | Complex blade profiles, corrosion-resistant parts |
Machining & Inspection
Every impeller goes through in-house CNC machining, dynamic balancing and NDT inspection before shipping - no shortcuts on parts that spin at thousands of RPM.
Applications
Engine cooling fans, HVAC and ventilation units, cooling towers, industrial blowers and compressors, agricultural machinery, marine and genset cooling.
