Silica Sol Casting is Suitable for a Wide Range of Materials

When it’s all about silica sol casting, Zouping Xinhui Precision Castparts Corp can come up with great outcome! They also work on other casting methods. But when it’s all about selecting the most typical investment casting method, the name silica sol casting often comes at the top. There are many benefits of silica sol casting and due to this reason many industries prefer to have products that are formed through this metal casting method. Stainless steel is the prime material for which silica sol casting can be done. Apart from this, for carbon steel and alloy steel such casting method can also be preferred.
Well, the prime advantage of silica sol casting is that it can deliver products with better dimensions as well as surface quality. The dimensions of a product can be maintained properly with this method. And the surface finish remains very precise with silica sol casting. However, this casting method is bit expensive than the water glass method. It can be two times higher is cost than water glass treatment process. In order to perform the silica sol casting, silica sol zircon sand is often taken as a molding material. This material can withstand against temp up to two thousand degrees. Due to this reason, such molding material is also expensive. And this makes the whole process costly as well.
With the silica sol casting, you can always expect for the higher level of surface quality that often remains smooth and the surface defects remains very less or rare. Inside surface defects mostly doesn’t occur with this type of material casting process. As far as the silica sol is concerned, it’s just like a milky colloid. These colloid grains can be very minute but they carry bigger surface area with comparison to their size. Due to this reason, when they are used for silica sol casting, they never affect the material’s natural color. Silica sol is highly soluble in the water. However, this is not soluble for other organic solvent. Silica sol can easily get dissolved in a mixture of water and alcohol.
Due to its low viscosity property, it can also soak those places where the water can also soak. This might be a big reason why the silica sol as a material can come up great level of dispersion as well as permeability once it is mixed with the other substances. Once the silica sol’s moisture contains starts to evaporate, it becomes a colloid grain and start to match with the surface of the material. After this the oxygen and silicon start to combine and form the grains. This makes silica sol a good adhesive as well. When silica sol is used as the molding adhesive, it can deliver great outcome for materials like stainless steel which is used for investment casting purpose.
- With the silica sol casting, there can be many benefits.
- This casting method is suitable for a wide range of materials.
- It can achieve precise tolerance.
- With this getting precise thin walls is often possible.
- The surface structure remains very fine and smooth.
Without the draft angles, critical shapes can be formed.
