On October 31, 2019 Bavelloni SpA finalized the acquisition of all (100%) of the shares of Glaston Mexico S.A. de C.V., a company of the Glaston Group.

 

Glaston Mexico, whose company name will become Bavelloni Mexico, is a business based in Guadalajara (Mexico) specializing in the sales and service of Bavelloni products and in the sales of Glaston HT machines.

The Company has been operating for more than 25 years, installing over 1000 machines in Mexico and other Central American countries.

 

 

 

The purchase of the Mexican subsidiary represents a milestone in Bavelloni's strategic plan, as it will allow the direct management of both commercial and after-sales activities in a very important area of the world.

Bavelloni Mexico will continue to be managed by Matteo Gherseni who successfully ran the subsidiary over the last ten years.

 

At the same time as the acquisition, an agency contract was also finalized enabling Bavelloni Mexico to continue promoting Glaston HT products in Mexico and Central America as the Official Agent for the Finnish brand.

 

The collaboration between Glaston and Bavelloni will continue unchanged also in Italy, where Bavelloni SpA is Glaston Official Agent, as well as in Brazil and Singapore, where Glaston operates as Bavelloni Official Distributor.

Glass tempering furnaces

 

1/Introduction

There are to main reasons for glass tempering

To harden the glass surface

To prevent, in case of glass breaks, to have very dangerous big pieces of broken glasses

 

A/Different glass tempering

There are 2 different glass tempering but only one( the thermic one) reaches the 2 targets

Chemical tempering

Thermic tempering

 

1/The chemical tempering

The glass is dived inside heated salts bath. The bath chemical composition depends on the type of glass. The target is to introduce at the glass surface more important dimensions cations from the salt bath, to replace the smaller ones which are already inside the glass. This is possible thanks to the temperature increase (more than 400 degrees Celsius) which allows to the cations to move.

During the cooling the cations movement stops and the biggest are kept in a smaller space than the one they normally need. So they are going to take more space and to harden the glass surface.

Moreover the surface is going to be in compression and increase the glass resistance to break.

But if the glass breaks the big dangerous glass pieces remain.

The chemical tempering is used for glass less than 5 mm thickness.

 

2/The thermic tempering

The idea is the same, to put the glass surface in compression. But a thermic way is going to be used.

The glass is heated( more than 600 Celsius degrees) in an oven for a time depending the glass thickness (between 1 and 15 minutes). And quickly cooled down (with air under pressure).

The surface quickly cooled is going to be in compression and the internal part of the glass is going to be in extension

This way to temper has some advantages

The glass broke in small pieces (less than 1 cm²), so less dangerous for people

It is less expensive

It is possible to temper all kind of thicknesses

 

B/The machines for thermic tempering

-The tempering vertical ovens

The tempering oscillating horizontal ovens

The tempering continuous horizontal ovens

 

2/Oscillating horizontal tempering furnaces

There are 4 areas: loading, heating, tempering/cooling, unloading

In the loading area the operator prepares the batch and waits to introduce the glass inside the oven till the previous batch leaves the heating area.
In the heating area the glass moves continuously with oscillation on rolls to prevent deformations.

When the temperature required is reached the rolls exit quickly the glass from the heating area to the tempering area where under high pressure air is sent on the surface.

In the same time a new batch is introduced inside the heating area.

When the glass, in the tempering area, reaches the right temperature to be manually unloaded it is driven to the unloading area where operators unload the glass.
