Aluminum alloy centrifugal fan blade used for rail transit centrifugal fan, Fan impeller be finished by integral casting. And casting method of fan impeller is metal mould low precessure casting, casting surface smoothness can meet Ra3.2μm.
The material of fan blade is aluminum A356. And all blower fan blade will do T6 heat treatment to imporve the mechanical properties of products. After T6 heat treatment mechanical properties can meet:
| Tensile strength | ≥280MPa |
| Yield strength | ≥220MPa |
| Elongation | ≥3.5% |
| Hardness | ≥HB85 |
The rotating speed of impeller is 1500RPM, the initial dynamic balancing accuracy ≤10g.
What are the advantages of integral casting instead of welding process:
* The overall consistency of the impeller is good
* The dynamic balance is good
* Production cost is lower
All impeller will be done X-Ray inspection and fluorescent penetration test in our factory, including CMM, tensile strength test and hardness test.
About casting production equipment we have:
* Aluminum low pressure casting furnace
* Vacuum casting furnace
* Injection wax machine
* Shell drying line
* Constant temperature and humidity room
* Plaster shell chamber
* Sandblasting machine
* Heat treatment furnace
Machining equipments
About machining equipment we have:
* DMG five axis machining center
* Three axis machining center
* Doosan CNC center Lathe
* General CNC Lathe
* Dynamic balancing machine
* Overspeed testing machine
* Radial Drilling machine
