Silica Sol Cast Impeller in China

Silca sol cast impellers made in China are widely used in assembling the pump and turbine construction induries.

* Material used for the Silica sol cast impellers

The material used to cast the impeller is stainless steel, such as AISI 304, AISI 316. Besides stainles steel cast impellers, some impellers are made in Aluminium. 

* Production process for the Silica sol cast impellers

In Fly foundry, we cast the impellers in process of silica sol casting, especially for the stainless steel cast impellers. Silica sol casting process can help to control a goode accurate dimensional requirements. Silical sol casting is one of investment casting process. 

* Surface treatment for the Silica sol cast impellers

After casting, the silica sol cast impellers will be first short blasted. Then, they will be treated by acid passivation or sand blasting. Such surface treatment will help to achieve a special layer with good anti-corrosion founction.

* Testing for the Silica sol cast impellers

After casting and machining, the impeller will be inspected by balance testing. The relevant parameters are required by customers with specification. In this way, the quality of impeller can be controlled, thus to ensure the application founction of the silica col cast impeller in China. 

Fly foundry casts various series of such silica sol cast impellers in China. If you have such inquiries, please contact us.
