The castings produced by investment casting have high dimensional accuracy and small surface roughness. They can be used to produce castings with complex shapes and precision that are difficult to produce by other methods. At the same time, they are not limited by alloy materials. Carbon steel, alloy steel, stainless steel, superalloy, etc. can use this method to produce castings, and both large and small batches are applicable.

We adopt the low-temperature wax-silica sol process to make the shell, the quality of the shell is stable, and the dimensional accuracy of the casting is high. It can be applied to thin-walled parts, small and medium-sized parts with complex structures, and can also produce medium and large parts. This process has greater adaptability and superiority (compared with medium-temperature wax) in the production of medium and large castings.
