Set Apart Between Silica Sol Spreading And Also Water Glass Casting

Products that are prone to high rust resistance are cast with silica sol. The reason for utilizing Silica Sol Casting is it has much less discrepancy of measurements, and also its surface high quality is exceptional.

On the other hand, water glass casting resembles a lot of investment casting. The only difference is that water glass casting entails water glass as a binder for the covering. Utilizing it, extremely complicated forms can be accomplished with amazing surface coating and outstanding precision. Water glass casting is much cheaper than silica sol casting.

Molding Product And Also Its Expense

The molding material in silica sol financial investment casting is silica sol zircons sand. This product can quickly hold up against 2000 degrees. However, this material is extremely costly, which is why the procedure of silica sol spreading has to do with 6.5 USD/kg.

While water glass spreading procedures use water glass quarts as a molding product and it is more affordable than that used in silica sol spreading. Water glass quartz can birth temperatures as high as 1800 degrees, as well as it costs about 2.5 USD/kg.


Silica sol spreading is the very best for metals that are most likely to go through deterioration. Different sorts of metals can be cast with it as it is rather flexible. You can obtain thorough casting with silica sol making use of the slim wall surfaces. Besides that, it also has remarkable dimensional accuracy as well as gives perfect completion at the same time.

One of the most essential advantages of water glass spreading is that it is eco-friendly, as well as a lot of complex shapes can be achieved with it. It has an excellent surface level of smoothness and also a couple of inside issues.

21 Reasons To Use Silica Sol Casting

Silica sol casting technology is a new kind of precision casting process. The difference between silica sol casting and traditional water glass casting is that the binding force of silica sol is the strong chemical bond, not the physical bond, so the structure of the product is finer and more compact than water glass sand. 

In addition, it has high strength, good toughness, high-temperature resistance, and corrosion resistance. The benefits are unlimited. Down below, we have compiled 21 reasons to use silica sol casting for your next project:

  1. The surface quality of silica sol precision casting products is good, and its performance can be comparable to that of investment castings.
  2. It has strong adaptability for complex shapes, thin-walled and complex inner cavity castings.
  3. There is no sand inclusion in precision castings by the silica sol process
  4. High dimensional accuracy
  5. Good repeatability
  6. Low labor intensity, short production cycle
  7. Flexible production
  8. Low pollution
  9. Strong anti-oxidation ability
  10. High wear resistance
  11. Corrosion resistance
  12. High strength
  13. Good wear resistance
  14. Good surface finish
  15. High dimensional accuracy
  16. Low shrinkage
  17. Good machinability
  18. Wide range of materials
  19. Few defects
  20. Can be used to produce metal parts with very complicated shapes
  21. The mold can be reused

The Takeaway:

Silica sol casting is an important process in the development of parts. This method produces castings with superior surface quality and fine details. It can be used for a wide range of applications including large scale industrial production, small and medium series as well as limited individual parts
