How to judge the stability of Silica Sol precision casting?

Silica Sol precision casting is a kind of product with high dimensional accuracy, which can be processed by selecting profile or casting carbon steel. The advantages of using silica sol for investment casting steel mould are low price of material, but the disadvantages are that the mould is bulky and has certain requirements for machining knife. Its hard for some manual operations. The interlayer drying time of Silica Sol precision casting will be further shortened. Although there are some products at present, the interlayer drying time of this kind of reinforced silica sol can be shortened to 1H. The shell making environment, especially the wind speed, will have strict requirements. Moreover, for castings with long and thin holes, the interlayer drying time should be appropriately extended.
The surface quality and high temperature strength of Silica Sol precision casting are good, the thermal shock stability of the whole product is good, the high temperature deformation resistance is strong, the product is a kind of less cutting or no cutting casting technology, such precision casting parts are also advanced casting technology in the casting industry.
