The vacuum precision casting process is conducted in a vacuum environment, effectively eliminating harmful gases such as hydrogen, oxygen, and nitrogen.
This ensures enhanced stability and superior product quality.
This process not only prevents the formation of impurities and inclusions in the final product by eliminating reactions between the molten metal
and atmospheric gases during the melting stage but also suppresses casting defects caused by moisture present in the ambient environment.
Furthermore, when casting alloys containing highly oxidizable elements, the vacuum environment minimizes alloying element loss,
thereby achieving the desired and stable alloy composition.
Due to its capability to produce complex and intricate geometries that are difficult to machine, vacuum precision casting is particularly suitable
for applications requiring high dimensional accuracy.
(This process is essential for manufacturing high-temperature components in gas turbines, as it enhances the mechanical properties
of the components while ensuring reliable performance under extreme operating conditions.)
