G.D's constant collaboration with its customers has made it possible to develop up-grade kits focused on obtaining continually improving machine line efficiencies.
Furthermore, the search for innovative solutions has also permitted taking advantage of all the possibilities offered by new technologies.

The wide variety of materials, the trend to progressively reduce the cost of materials and the simultaneous need to maintain the quality standard in the finished product, all require the feasibility to retrofit advanced and more flexible technical solutions.

G.D's longstanding market presence and consequently the enormous installed machine pool, with various generations of machinery in production within the same factories, generate the opportunities to standardize the equipment by means of up-grade groups.
