Interview with Giuseppe Bitetti, Head of Technical Department FINESTRENURITH

“The cooperation between FINESTRENURITH and GRAF Synergy started already in 2017, with the purchase of the first welding machine “four heads”  EVO for the Ginosa (TA) plant.

The need that pushed us to contact GRAF was to improve the aesthetic finish of our products and in particular of the welds, the real weak point of PVC windows which, before the advent of GRAF Synergy’s V-Perfect technology, stood out easily from the wooden ones due to the imperfections of the welds and the signs of cleaning.

The first welding machine proved to be very successful, so three more followed, again for the Ginosa plant: a second SL4 FF EVO, an SL4 FF DIA and an SL2 FF DIA. They were all installed on pre-existing lines from another manufacturer without any major difficulties.

In the Gonzaga (MN) plant, however, GRAF provided us with a new complete line, from work centers to glazing benches. From the initial design stages, GRAF actively collaborated with the FINESTRENURITH design team to create a targeted and optimized layout based on our specific needs. The layout was developed thanks to the “Fast Forward Plant” system, which takes full advantage of GRAF’s skills in the design of production lines for PVC windows and doors.

Innovation, Made in Italy, geographical proximity, assistance and ability to listen to the customer to provide real solutions: these were the strengths that pushed us to choose GRAF as a partner over other competitors.

The first, most evident, improvement obtained thanks to GRAF technology is also the one immediately perceivable by the end customer, i.e. the perfect aesthetic rendering of FINESTRENURITH frames, since thanks to the introduction of V-Perfect technology the level of finishing of the corner is considerably improved. However, at a company level, we have certainly improved the quality of the work of our operators, thanks to automation and consequently we have perfected the control and optimization of our production processes.

Even if it is not possible to make a direct comparison, thanks to these interventions we have found a level of productivity and efficiency of our plants fully in line with our, I must say high, expectations. Having automated the production process, the cut profiles, doors and frames are all managed through automatically managed transport and logistics. This made it possible to eliminate trolleys from the factory, both for profiles and for doors and frames, thus eliminating downtime for searching and managing pieces. Furthermore, we have not recorded any substantial compatibility problems of the machines with the other machinery or tools we use.

On a collaborative and support level, the relationship with GRAF during the design, purchase and implementation of our project was excellent, in all phases and at all levels.

The training of personnel and the use of the machines in standard configuration did not give any problems. With the machines developed together specifically for the Gonzaga plant, i.e. customised and specific to us, there was obviously a slightly longer physiological gestation period before they reached full use and efficiency.


Summing up, GRAF’s willingness to quickly find shared and concrete solutions to our problems has been instrumental in achieving our quality and productivity goals. This success has required some additional investment in technology, machinery and process optimisation, but has had a decisive positive effect on the quality of our final product and the overall productivity of our factories.”
