Product Description

Aluminum alloy centrifugal fan impeller used for rail transit ventilation system, Fan impeller is finished by integral casting. And casting method of fan impeller is plaster low precessure casting, casting surface smoothness can meet Ra3.2μm.

The material of compressor impeller is aluminum A356. And all compressor impeller 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 5000RPM, 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.
