Silica sol precision casting is a product that requires very high specifications for precision. We can first choose aluminum profiles or forged alloy steel for production and processing. The advantage of using silica-sol precision casting steel mold shells is that the raw material price is low; the disadvantage is that the mold shells are relatively heavy, and there are certain requirements for the production and processing of knives. For some manual productions, it is more laborious. How do you judge the high-temperature compressive strength and stability of silica sol precision casting?

The drying time of the solid layer of silica sol casting will be further shortened. Although there are some products at present, they can reduce the drying time of the solid layer of silica sol to 2 hours for this improvement, especially in the shell-making environment. The wind will have its strict requirements, and for castings with long and thin holes, the drying time of the solid layer should be increased appropriately.

The surface quality of silica sol precision casting is good and has high temperature strength; the thermal shock stability of the whole product is good; the lost foam casting has strong resistance to deformation at high temperature; and the product requires less drilling or no drilling at all. Casting technology, such as CNC Machining Services is also excellent in casting technology in the foundry industry.

The high-temperature strength and stability of silica-sol casting are relatively good. When we use this casting process in practice, we need to pay attention to the above points.
