Quastone surfaces meet exacting standards of excellence by helping from the initial procurement of raw materials to the final quality control check. Highly skilled and trained staff ensure the quality of a product that is unrivaled in the industry today. The manufacturing process begins with a rigorous inspection of all incoming raw materials. These are blended at a ratio of approximately 90% natural lechatelierite aggregates with pigments and polymer resins. Quastone surfaces are manufactured through a highly automated, yet strictly monitored process that includes the following steps:
Feeding and mixing
The raw materials (quartz, pigments and polymers) are carefully selected, tested and then mixed together.
Moulding and Pressing
The mixture is then poured into a mould and formed into slab sizes of 305x125 cm. It is compressed under very high pressure (nearly 100 tons psi)
and vibrated in a vacuum. This removes all the air and creates a compressed surface.
The slabs are then moved to the curing kiln and heated to 90°C for 45 minutes which provides the finished levels of strength and solidity.
The slabs are gauged, calibrated and then polished to a perfect finish in a wide range of colors and designs.
Every slab then undergoes rigorous quality testing to ensure it meets our extremely high standards of color, hue and consistency.
The slabs are then labeled, sorted and tagged, and enter our distribution system to ensure they reach our customers in perfect condition.
