BAVELLONI SPA SIGNED AN AGREEMENT FOR THE ACQUISITION OF GLASTON MEXICO

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.

The glass

Considering the chemical composition it is possible to consider 3 different glasses.

The sodo-calcic glasses

The boro-silicat glasses

-The vitro-céramique glasses

 

The sodo-calcic glasses are mainly used in architectural markets.

The boro-silicate glasses, due to the low distention coefficient, are present on markets where are important temperature differences and with contact with fire

A very well-known trademark on this field is Pyrex.

The vitro-céramique glasses, with also a low distention coefficient are present in household appliance (oven doors, cooking plates, chimneys…)

 

This important difference in the chemical composition has results in their properties and using areas. Silica represents between 50% and 90% of the total composition.

Moreover :

-The sodo-calcic glasses have additions of calcium and sodium oxides.

-The boro-silicate glasses have boron oxide.

-The vitro-céramique glasses have aluminium oxide.

There are other oxides (Baryum, Lithium, Magnesium, Potassium, Zinc, Titan….) each giving a specific property, (color, melting point, chemical resistance, mechanical properties..).

A very interesting thing is that the glass compositions have not very different between to-day and 1600 years ago.

The flat glass is mainly used :

-70% in architectural

-20% in automotive

The car we have dreamed when we was a child

 

Is not exactly the same we drive to-day.

 

-10% in décoration and appliance

 

In architectural and automotive is required the more perfect transparency for the light and the weakest transparency for infrared light, because the solar energy is carried by infrareds (to minimize the increasing of temperature inside the building or the car). Infrareds carry also, during winter, the heat to outside and increase the energy used for heating.

Adjusting the glass chemical composition the more important flat glass suppliers Saint-Gobain, PPG, Pilkington, AGC …) succeed to manufacture such glasses.

Glass is transparent, but you can see that, in fact, it has a green colour (due to iron presence) more obvious for high glass thickness (more than 12 mm).

This green colour can be removed with manganese or selenium addition.

The glass can be also coloured.

Cobalt gives a blue colour

Selenium in large quantities gives a red colour

Copper oxide gives a turquoise colour.

With Nickel depending the concentration you can obtain a large colour range from blue to black

With tin you have shadowed white

With iron you can have, black, brown or green

With Titanium black yellow

With gold several different yellow

With uranium addition from yellow to fluorescent green

With Silver nitrate from orange to yellow

 

 

Colored glass from Egypte, around 600 years before JC

 

The colors grades are also depending from glass heating and cooling (like in pottery).

 

You can colour all the glass surface. Generally this operation is done with rolls (see the area for colored glass in the section machines comparisons) engraved or not, or with pistols.

You can also put a colored image on the glass (with screen printing or digital printing). For more information go to the corresponding area in machines comparisons.

 

Screen printing from Andy Warhol

 

 

 

 

Other more industrial exemple.

 

 

After this operation the glasses go inside a furnace to fix the color on or inside the glass depending the final using (advertising, architectural…).

 

 

Industrial glass manufacturing.

The different products are sent in a melting oven. The industrial process is called "float"

This process was design by a person called Pilkington. This invention allowed to decrease drastically the manufacturing cost and opened huge market for flat glass.

At the oven outlet the glass flows on a tin bath.

The glass goes inside rolls allowing to produce glass in the thickness required (3, 4 ,5 ,6 , 8 ,10  ,12 ,15 ,19 mm), is cut and sent to the processing companies.
