The processing technology of silica sol precision casting is relatively complicated and can not be controlled, and consumes materials in the processing process. Therefore, this processing method is very suitable for processing small parts with high precision requirements and complex shapes and difficult to process.

Next, the selected metal is melted and prepared for casting. This stage requires careful control of temperature to ensure that the metal has the right viscosity and flow characteristics for filling the mold without creating defects. Once the metal is ready, it is poured into the mold and allowed to cool. The cooling rate can significantly influence the properties of the final product, as it affects the microstructure of the solidified metal.
