The nouns of precision casting and water glass, silica sol casting, and coated sand are not known if it is not a foundry industry. In the process of casting, it is necessary to know not only its methods but also its technology and material.
Is there no casting order in the year? Do you want to find a foundry?
Casting order net to find castings order, purchase castings, consult casting technology problems, all here!
The wax of water glass is very soft, and the wax of silica sol is very hard. The surface of the silica sol is better than that of water glass.
Both of them are only different in the quality of the manufacturing type. The silicon sol made of the type guests are more suitable for precision casting. The surface of the product is smooth, the deformation is small, the shrinkage ratio is small, and the size precision does not need two processing.
But silica sol is basically made of small products, and the products made of sodium silicate lost foam are relatively large. Both of them are only different in the quality of the manufacturing type. The silicon sol made of the type guests are more suitable for precision casting. The surface of the product is smooth, the deformation is small, the shrinkage ratio is small, and the size precision does not need two processing. The wax of water glass is very soft, and the wax of silica sol is very hard. The surface of the silica sol is better than that of water glass. The principle is the same. The wax, the surface sand and the adhesive are different.
So to distinguish between precision casting and silicon sol casting etc. which precision high should further from its material analysis. It can't be judged only by its casting method.
