Step 2 : Placing divider mould into steel mould
Steel mould is prepared and divider mould which molds the tile design will be placed inside the steel mould.
Step 3 : Pouring colours into the mould as the first layer
A liquid mixture consisting of white cement, natural marble powder, colour pigment, and additives (to be mixed to the right colour) is poured by hand into the mold. Different liquid mixtures will be needed to create different colours in one tile.
Step 4 : Making next layers
The second layer is a very fine and dry mixture consisting of grey cement and fine sand is put on top of the first layer. The second layer is very thin and has the function of absorbing water from the first layer.
Applying a mixture of sand and cement as the third layer (back layer) till the required thickness of tile is achieved.
Step 5 : Pressing by hydraulic pressing machine
All the materials will be pressed by hydraulic pressing machine. Moisture from the liquid colored layer will be absorbed through the dry back layers. Tiles will be pressed twice to have a good strength.
Step 6 : Forming tile and taking out tile from the mould
Tile has been formed and taken out of the mould. Now, we can see a beautiful tile with pattern and colors.
Step 7: Curing tile
After the forming stage comes the curing stage. Tiles will be cured under water and then placed on racks for curing at room temperature.
Step 8: Coating with sealer, checking quality and boxed
After tiles are dried completely, they will be treated with sealer to perfect surface of tiles and go through serious quality control by checking piece by piece to carefully select really good tiles before packaging and palletizing.
