Industrial production process of ceramic tiles

We can identify two different types of industrial production processes for ceramic tiles:

Double fired: In this case the process is dry. There are two firing stages: the first stage is the firing of the support and the second stage is the firing of the glaze.

Single firing: The raw material is wet-processed and subsequently spray-dried. There is only one cooking stage, followed by drying and glazing.

Ceramic tile production cycle

1 | Preparation of raw materials
In the first stage, preparing the dough, the dough must have the proper particle size distribution and particle shape;

2 | suppress
The powder is directed into a mold for the final finished shape;

3 | dry
Raw tiles go into a dryer where they are blown dry by hot air up to 200°C to remove all remaining moisture;

4 | Glazing and Decorating
The dried tiles are airbrushed and then decorated by digital printing. A second glaze is also applied on both sides of the tile;

5 | Firing
The tiles are gradually heated from 20°C to 1200°C and then cooled to 70°C;

6 | Quality Check
All tiles are quality controlled aesthetically and functionally.


We receive customer inquiries from manufacturers of machines and systems for the ceramics industry.
The problem he posed to us was to design a system for internally cleaning the glazer for “waterfall” glazing applications on ceramic tile.
The machine consists of a minimum of 3 to 5 modules: an input module, one to three glazing modules, and an output module.
The glazed central module is equipped with nozzles for glazing tiles. The electronic management system synchronizes the movement of the spray nozzles with that of the tiles to be glazed, avoiding overlapping of different channels.
The client’s request was to design an automatic system for internal cleaning of the glazing machine. Timely glaze removal is critical to the quality of subsequent glazing cycles.
Priority areas for cleaning include tank bottoms, sides, conveyor belts and spray nozzles for glazing.


HAPOO’s technical department has developed a modular and efficient cleaning system for the interior of glaze machines.
This solution uses only water and no detergents. It involves installing 4 pipes on each central module, 2 on each side, and one above and below.
Each pipe is equipped with a J-shaped flat nozzle. Depending on the location of the pipe, the number and position of the nozzles may vary.


The system developed by HAPOO ensures the highest level of flexibility and high performance, ensuring complete cleaning of the machine.

flat nozzle

Standard J-pattern flat nozzles are available in a wide range of flow rates, spray angles, thread sizes and materials. They produce a finely atomized spray with just the right amount of impact in a variety of industrial applications.
