ISO 8062 CT 6
Silica sol castings are mainly used for products with high corrosion resistance and precision dimensions, since silica sol
steel casting can have much better surface quality and less geometrical deviation of dimensions. The main silica sol steel
Usually, Silica sol casting parts tolerance within GB/T6414, CT5~6, weight range from 20 grams to 50 kilograms, the surface
finish is Ra6.3.
Silica Sol Casting vs Water Glass Casting
material, which can stand temperature up to 2000 degree.
The silica sol investment castings have better dimensions and surface quality, but just more expensive than water glass casting.
Cost of silica sol casting is almost twice than the cost of water glass casting. Below are the main differences between solica sol
casting and water glass casting.
|Silica sol casting||Water glass casting|
|Machining||No or less machining||More machining|
|Material||Stainless steel||Carbon steel & alloy steel|
