Ask the expert : How are our tiles tested?

We manufacture porcelain and ceramic tile at our factory in India with varieties of surface applications, categories such as glazed, double loading, full body, 2cm pavers, etc. In order to maintain the quality consistency we have to follow a system of quality control during every production.

In this article we will try to try to brief you with parts of that quality control process. Tile manufacturing is a complex process with multiple stages in the production, even if one of the process is flutated then it can generate problems in the end product. Here we have covered 9 of the most basic quality control parameter which we follow in each production.

 

1. Color Matching

For every product in our collection, we maintain the master tile in the design office at the factory. Before the production starts, our design and quality team match the color and surface of each product by taking a sample tile. Once it is approved, the actual production starts. This process maintains the product color and surface consistency in every production.


 

2. Surface flatness

When the product comes out of the kiln, it passes the polishing (if required) and rectification process. During this process, our quality team inspects the surface flatness report by flatness machines as well as by manual inspection. Surface flatness is one of the most important attributes of any tile and it is our priority to maintain that as per international standards.

 

3. Flexural strength (MOR)

We check the MOR twice during the process of tile production. First is in the laboratory, when we test the raw material and we make a micro tile. Second is during the production of actual tile and it is getting packed. We have a MOR test machine at each factory to check the parameter.

 

4. Water Absorption

We check the absorption report of the tile on the daily basis. For that, we heat the tile in the water and then cool it down. After that we check the water absorption by the WA machine. Our porcelain tile maintain WA under 0.05% and ceramic tile maintain WA between 

 

5. Shade Variation

Before packing the tile, the sorting team checks the shade of the tile. We maintain a batch number for each shade of the tile. Generally for the less quantity production of a particular design, we have one batch / shade of the tile per production. For highly sensitive colored tiles or for large quantities of the one design, we have to manually check each tile before packing. They give a name of multiple batches during the production of each product.

 

6. Deviation in Length & Width

We have to check the dimensions after the rectification of tile. The parameter should be as per ISO regulation. We check the length from the sides, diagonal length as well as the thickness of the tile for each batch of the production.

 

7. Marker test

We choose the tiles randomly from any particular batch and we do the marker test on them. For that, we have run a marker / ink on the edges as well as central parts of the tile and then we clear them with the powder. The tile passes the marker test if the ink is removed with ease.


 

8. Glossiness

This test is particular for the polished tile. For the polished tiles, the glossiness factor is very important. We check this on a regular basis during the production and we maintain the glossiness above 95 %.

 

9. Other surface related problems

After the tile passes above parameters, we lay a few tiles on the floor and check for any other surface related problems. This includes checking for the pin holes, polishing patches, kiln dust, etc. This process has to be done manually by an expert in quality inspection of the tile.
