What's the difference between water glass and silica sol process?

Both belong to wax loss precision casting. The difference is that the binder used in the shell making process is different. The surface quality of the shell is different, resulting in better surface and higher dimensional accuracy of the product casting cast by silica sol, but the cost is also higher than that of water glass casting.

The product cast by silica sol has good casting surface and higher dimensional accuracy, but the cost is also higher than that of water glass casting.

Most of SDA accessories are consumables, so we choose more economical water glass process, which not only ensures the application, but also ensures the cost control of customers.UMC improves the overall surface quality by improving the water glass casting process.
