Some figures on the last Glasstec.

 

The show held in October 2018 in Dusseldorf saw a growth of almost 5% in the number of visitors, slightly lower than the records of 2012 and 2014.

 

The show is truly an international fair with more than 70% of visitors coming from abroad.

On the other hand the number of exhibitors is in withdrawal (figures not given by the organizer) with some hall not completely filled

There are no translations available.

New options for Battellino robot for double glazing

 

- BAR CODE READER: this allow to the customer to create bar codes that can give the machines all the information about: Type of frame ( aluminum stainless steel) thickness of the 1^ 2^ and in case of triplex 3^ glass; Thickness of the frame; information if the glass is a simple double of a triplex.

- SHAPED GLASS a special environment on the panel ( see attachments) allow the customer to choose from different kind of shapes of glass to work.

- MONUMENTAL GLASS opportunity to work also frames of only 4 mm, this device is particularly interesting for the companies that work with restoration of old buildings. Really interesting because this kind of glasses are really difficult to job well also manually.

-SPEED faster then in the pass the new version runs at 18 mt/min also the working of the corners was modified to run faster ( a glass of 100x80cm can be done in approximately 45 sec.

- NEW TOUCH SCREEN PANEL if in the older machines were equipped with a commercial PC, the new models are equipped with an Industrial panel, more powerful and more reliable, like in the past, also this new touch can be delivered in the language of the customer.

- NEW PUMPS thanks to a new supplier that helped us creating with us a special pump for our robot we have had the opportunity to offer the robot with a better price

- 4.0 MACHINE the machine can be certificated as 4.0 industrial machines that means higher score to access to European founds.

Technical news for Battellino Italian machines manufacturer

- STRONGER INLET AND OUTLET ARMS we change the system of inlet and outlet conveyor to allow to our machine to can sustain more weight following the requests of our customers.

- NEW GASKET SYSTEM  to help our customers to maintain in better conditions their machines, we modified the gasket set of our spindles, to avoid more and better any problem of leak of water.

- NEW WIDE TOUCH SCREEN we improved our machine with a multilingual wide touch screen. The panel, equipped with our new software divided into environments,  gives to the operator the opportunity of set easily the speed of work, the thickness of the glass, the operations of the pneumatic motors and the working of the water pump moreover shows to the customer , the total and partial meters worked by the machine, the way of working of the machine in each phase of work, helping him also in the maintenance of the parts.

- NEW SYSTEM OF GUIDES FOR THE DIAMOND AND POLISHING MOTORS,  a new system of guides for the motors give them more stability to improve more possible the quality of the glass.

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.
