Silica sol casting boiler air帽 thermal shell casting features the following:

The boiler bonnet structure is complete with sharp edges, as the high-temperature steel water during shell casting fills the mold cavity effectively, replicating the structure of the boiler bonnet, thus preventing under-filling, particularly for the precise sizing of the bonnet's small holes.

The boiler hood surface is smooth due to the high shell casting temperature, good permeability, and small difference in steel water temperature, which prevents defects like cold segregation and blow holes on the hood surface.

3. Boiler fan caps have a low return rate, achieving the purpose of minimal or no processing, and deliver on time.
