EMPHASIS ON TECHNOLOGY COMMITMENT TO PRODUCT DEVELOPMENT & QUALITY CONTROL

Creative & innovative methods in manufacturing deliver the cutting edge in ceramics. RAK Ceramics has a distinct edge due usage of the latest manufacturing technologies to produce a very wide range of products suited for various kinds of applications and budgets.


The latest state of art machines and equipments were inducted by RAK Ceramics over the years and the best tile designers in the world were used to convert concepts into reality. The Company is flexible to adapt the external market shifts and this continues to remain as the sustained strategy of being focused and aligned with market realities.

The latest state of art machines and equipments were inducted by RAK Ceramics over the years and the best tile designers in the world were used to convert concepts into reality. The Company was flexible to adapt the external market shifts and this continues to remain as the sustained strategy of being focused and aligned with market realities. Flexibility to external market that the company had to be forward looking and anticipate "changes" in the market place as routine and address all such issues proactively.



A synopsis of the technologies in operation at RAK Ceramics’ plant mentioned below:

The salt & pepper models (GP Series) :
These models are full body tiles produced with the utilization of a dosing system. Various types of colour pigments in liquid form are mixed with the slip body in certain proportions by dosing system while simultaneously being fed into the spray drier. The dried clay granules (mixture of colour pigments and clay body) is fed to the Hydraulic Press and Pressed according to the required size. The clay tiles are then dried in the Horizontal Drier and subsequently fired in the Roller Kiln. The mixture of colour pigments creates the salt and pepper effect on the body of the tiles. These models are available in both Unpolished and Polished finishes.

The soluble salt models (GP Series)

Silk screens are used as the source of the designs to be printed on the surface of the clay tiles. Using the printing paste made of alkali or colouring salts, the designs are printed on the proper surface. Soluble salt solution is applied over the printed surface to aid the penetration of the print into the tile body by 2.8 mm to 3.2 mm deep. After the drying stage, the tiles are fired and subsequently polished to obtain the natural marble effect. These products are available in Polished finish only

The full mass products (GPM Series) :
These models are characterised by the natural design of marble veins and shades. To achieve this aesthetic design, a sophisticated technology called RDM (Rotary Diaphragm Mixer) was adapted. The tiles are manufactured with the use of various multi-coloured powders differing in their morphology. The basic powder and the coloured ones flow through the various pipes while coming from the hoppers on the service platform over the press. The Rotary Diaphragm Mixer (RDM) simultaneously mixes the different powders and feeds the feeding hoppers with a series of coloured spots inside the basic powder. After pressing, the tiles are fired and after subsequent polishing, the finished product resembles natural stones and marbles, having naturally created veins or shaded effect. These models are available in both Unpolished and polished finishes.



The double-charge models (GPD series) :
These tiles are produced by a sophisticated technology known as "Double Charged". Multi-coloured powders are used to obtain the typical appearance of a natural marble or granite. The double-charging process is rendered by super imposing a layer of micronized powders, which after pressing, firing and eventual polishing, an aesthetic effect of a natural marble or granite is evolved to a layer of the basic tile body. These models are available in both Unpolished and Polished finishes.

The double-charged with soluble salt printing models (GPDSS Series):
These tiles are a combination of both Double-Charged and Soluble Salt Printing Technology. Tiles similar to natural stones and marble can be created using this technology. These products are available in Polished finish only.

The double-charged with dry glaze application models (GPDRG Series) :
These tiles are produced through the combination of both Double-Charged and Dry Glaze Application. Dry glaze application transpires at the pressing stage itself. It is applied on the of the body powder, then pressed and fired. The finished product has a resemblance of natural stones with unrefined surface. These products are available in unpolished finish only.

The roll feed models (GPRF Series) :
This technology helps to make tiles that resemble natural stones and marble with "veined", "shaded" and “stratified” effect. This is created by the application of several components (single colors, mixed colours flakes, mixed with granules) that can be batch and guided into mould cavities. The end product will have a natural look without any geometric or repeated effect. The typical vein look is present over the entire body of the tile, thus rendering an unlimited guarantee of elegant look. These models are available in both Unpolished and Polished finishes.

The twin press (Double Pressing Technology) :
This technique involves first pressing step that forms the semi-compact body, in which layers of powder decoration are applied, followed by the actual or final pressing. The importance of double pressing certainly lies in the limitless possibility of creating new "Grew Porcellanato" tile products whether glazed or unglazed, in the pressing stage and of developing products with effects that aesthetically give no reason to envy rustic or polished natural stone. This also helps to reproduce semi-precious tone such as Quartz. These models are available in both Unpolished and Polished finishes.

Technoslate :
The name "Technoslate" identifies a new technological process, which is a major innovation in the field of Porcelain tile; a system capable of producing through-bodied vein effects on textured rustic tiles. With this new technology, the tile comes out of the press with the veins already visible, making it possible to create all kinds of products, from smooth surfaces (which may undergo final polishing) to textured surfaces. These products are available in Unpolished finish only.



The rustic "GP" tiles :
Rustic models are usually made from the basic body granules, pressed with structured punches and enriched with a suitable quantity of glaze and other application materials. To get the natural and elegant look of genuine stone, various types of printing and surface applications are employed, then intermittently sprayed and brushed on the surface thus enriching the natural effect. International shade or colour variation, which is an integral element of the design is likely to be observed. Beside the familiar glazed surface and unpolished finish, these products are also available in Lapato finish.

RAK Ceramics is a Rs 7000 crore Global Conglomerate that supplies its products to over 160 countries and has been officially recognized as the World's fourthLargest Ceramics Manufacturer and Asia’s largest tile manufacturer with a Global Annual Production output of 3,00,000 square meters per day of ceramic and porcelain tiles, 50 Million pieces of bath ware and 20 Million...
