A FASCINATING PROCESS
One of the most attractive features of engineered quartz stone is the unlimited range of multicolor patterns which provides the slabs with that unique natural stone feel.
How is this high variability possible?
- The quartz sands, after being selected in color and grain size, are mixed with resin and color pigments in different mixers. Each one of these mixers produce a mixture with a precise color and consistency.
- These different colors mixtures are combined together composing any possible homogeneous patterns.
- Once the combined homogeneous mixture is ready, it is carefully distributed in rubber mould and pigmented powders or different colored mixture could be added – with automatic robots, to produce thin or large veins. This creates the so-called natural stone look.
- The mixture inside the mould is then compacted into a slab inside a special press through a particular process: the vibro-compression under vacuum.
- Then, the slabs are hardened by heating them in a special kiln up to 100-120 °C, finally the rubber mould is removed and the hardened slabs are cooled down in a cooling tower.
- These raw slabs should be processed in the finishing line in order to remove any possible surface imperfections and obtain a perfect surface with brilliant colors and with the real stone texture.
- The finished slabs are then used for producing countertops, interior cladding and flooring.
