Interesting and important impacts on the environment

BDF Dual Axial Cooling is an economical, simple, but flexible and powerful solution to better control mould temperatures
Glass containers have some known and unquestioned advantages: they are natural, hygienic, impermeable, durable and also aesthetically fashionable and pleasing.
But this no longer seems enough.
The strong competition of alternative materials such as P.E.T. and cans, in terms of costs and lightness, has pushed the glass container industry more and more to go beyond the limits inherent to the actual productive process.
While maintaining the characteristics of stability and resistance, the production of lighter containers introduces some important benefits:
-    reduced consumption of raw materials;
-    less thermal and compressed air energy used in the process;
-    reduced costs related to the transport, moving and stocking of the containers.
If we also consider an additional increase in the percentage of recycled raw materials, the important reduction in environmental impact can be appreciated in about 15% savings in CO2 emissions.
While maintaining quality, efficiency, speed and operational costs, container weight reduction can be formally achieved by means of improved control of process parameters, mainly with timing and temperature distribution, during gob forming and in the following steps of loading, pre-forming, reheating and forming.

The efficiency of DAC in lightweight production
Loading an extremely homogeneous gob in the blank mould, with a constant weight and a high temperature, enables to set the subsequent steps with the best conditions to achieve the required needs of...
