1. Increase the shell strength. Thin shells must have the weak point that the overall modeling strength is not high. Through the application of silica sol, it can increase the strength of the shell shape, so that the thin shell products processed by the precision casting of the thin shell have high strength, and it is not easy to Structural damage occurred during the application.
2. Increase casting finish. Since the particles of silica sol are colorless and transparent, they will not affect the true color of the covering. Therefore, when applied in thin-shell precision casting, they will certainly play a role in increasing the smoothness of the casting, so as to enhance the texture of the product and make The appearance of the product becomes better.
3. Reduce costs. Compared with the application of ethyl silicate, the application of silica sol in thin-shell precision casting requires less cost and can play a good role in reducing costs.
In addition, the application of silica sol in thin-shell precision casting can also improve the operating conditions and optimize the entire casting process.
