The size of silica sol casting itself is not large, and the accuracy requirements are not very high, so you can consider using tin-bismuth-aluminum frame as the mold. The weight of the tin-bismuth mold is relatively heavy because it contains bismuth, but for the production of complex molds, the production time is short and the machine cost is saved.

Silica sol casting is suitable for casting of various types and alloys. The dimensional accuracy and surface quality of castings produced by this technology are higher than other casting methods. Casting methods are difficult to cast, difficult to handle and high temperature resistant castings. If we want to produce products with simple shapes and not too large sizes, we can choose profiles or use cast steel to process products with high dimensional accuracy.
