Chemical tempering is one of the methods used to increase the surface hardness of glass. In this method, it is ensured that the sodium atoms in the glass are replaced with potassium atoms in the region close to the surface. This creates a tension on the surface.
It gives strength and hardness to the glass. In the glass tempering furnaces produced by our company, the glass is heated by a constant temperature increase so that the glass is not broken by thermal shocks, then it is immersed in the salt bath. After being kept in a salt bath for a sufficient time, it is cooled slowly. All this is done automatically with a pre-installed program.
Chemical glass tempering furnaces are designed according to customer requirements and glass holding baskets are designed by our company. Tablet, telephone, solar panel and television glass are examples of glass produced by chemical tempering. This method is a unique method for increasing the strength of thin glasses.

For the maximum life of the furnace and the longer use of the furnace equipment, we recommend that the heating rate of 10°C/min is not exceeded. Flammable and explosive products must not be used in the furnace.
The salt which is inside the furnace must not touch with any water piece. For long-term breakdown stays the salt may get solid. In this cases, it is better to pre-heating without a sample.
Chemical Glass Tempering furnaces are available in wide a ranges of volumes and temperatures from 650°C to 900°C continuous use.
