Which precision casting is relatively high, water glass or silica sol casting?

Date：[2023/10/23]

If you are not in the casting industry, you may not be familiar with the terms precision casting, water glass, silica sol casting, and coated sand. During the casting process, you not only need to know its method, but also its technology and materials.
The wax of water glass is very soft, while the wax of silica sol is very hard. The surface of silica sol products is better than that of water glass.
There is only a difference in the quality of the manufacturing mold between the two. The mold produced by silica sol is more suitable for precision casting, and the products produced have good surface smoothness, small deformation, small shrinkage ratio, and precise dimensions without the need for secondary processing.
However, most products made with silica sol are small, while products made with water glass lost foam are relatively large. There is only a difference in the quality of the manufacturing mold between the two. The mold produced by silica sol is more suitable for precision casting, and the products produced have good surface smoothness, small deformation, small shrinkage ratio, and precise dimensions without the need for secondary processing. The wax of water glass is very soft, while the wax of silica sol is very hard. The surface of silica sol products is better than that of water glass. The principle is the same, and the wax, surface sand, and adhesive used for both are different
So to distinguish between precision casting and silica sol casting, which has higher precision, it is necessary to conduct in-depth analysis from its material. It cannot be judged solely from its casting method.
