Foundry Silica Sand
We produce Silica Sand ranging from 30 AFS to 85 AFS. Our Kolayat Silica Sand has semi rounded to sub-angular , smooth textured grains, SiO2 > 98 %, Acid Demand value < 5 ( cc of 0.1N HCL for 100 gm of sand) and gives excellent Mould strength and Scratch hardness. All these features make this sand eminently suited to various moulding processes and different resins. Our fully mechanized Sand Processing plant spread over 10 acres has inbuilt blending and segregating processes and four stage washing. This gives consistent Size cut-offs, Clay content as low as 0.1% and excellent control over Fines. Three sieve distribution is above 80% .
Total Quality Control
Typically, big foundries have hundreds of Tons of Sand in the System at any point of time and the final casting results depend on a number of factors. Silica sand is a low cost but high effect item in the casting process. Unless consistency of the sand quality is strictly maintained, mould/core quality and consequently the product quality cannot be ensured. This quality consciousness cannot be limited to the engineers and Quality control people. Even the JCB operator who loads the truck or the laborer who fills the bags must be taught his role in quality consistency. We, at Qualicy understand this and take pains to ensure that our customers can rely on us.
