Interview with Sebastian Blaser

In conversation with Sebastian Blaser, planning painted body Győr AUDI HUNGARIA Zrt

The Audi plant in the Hungarian Győr is the first paint shop where IDDA.Seal is running in series production. Around 60,000 vehicles have already been sealed with the new technology. And the next development step is already being planned. Sebastian Blaser is the former technical coordinator in the painted body planning department and has led the line launch of the new technology. 


 


Mr Blaser, what does Audi manufacture at the Hungarian plant in Győr?

Among others, we manufacture the A3 and S3 Cabriolet, the TT, TTS and TT RS as Coupé and Roadster as well as the Q3 and Q3 Sportback. The plant has a total production capacity of around 750 vehicles per day. For the Q3 and Q3 Sportback, we are using the new IDDA.Seal technology for the first time in series production. 

In your opinion, what are the major technological challenges in sealing the car body today?

The biggest challenges today are the complex vehicle geometries. We want to make sealing as highly automated as possible and with as little material as possible. Especially in cosmetic sealing, for example on the rear gutter or in the lamp dome of the vehicles, where IDDA.Seal is used first, the highest precision is required. 

What were the reasons for the development and introduction of IDDA.Seal from your perspective?

With the conventional technology, we have reached the limits of cosmetic sealing. That's why we have developed this new application technology together with Atlas Copco, where our main aim is to work more environmentally consciously, i.e. to apply more precisely and thus save sealing material, improve ergonomics for the employees and of course also increase productivity. 

What are the concrete advantages of IDDA.Seal?

By controlling every single drop of PVC, we can apply beads much more precisely and flexibly. We can create different bead geometries and widths, we can go around curves without accumulating PVC material, and we can apply PVC from different distances. We can thus also seal complex vehicle geometries quickly and with pinpoint accuracy. 

In your opinion, what were the success factors for the successful development and implementation of the new technology?

The major success factor were our employees. Cross-location cooperation was decisive, with each employee putting their heart and soul into the whole project, and the good cooperation with our development partner Atlas Copco. Especially here at Győr we had the opportunity to carry out tests close to the line, which was very important for a smooth integration of the new application technology into the line. 

What are the next steps in this innovation project with Atlas Copco?

After the successful start-up of the cosmetic sealing, I am looking forward to tackling the logical further development, the so-called seam sealing, which among others is used to seal the underbody of the vehicles. We expect to achieve particularly large material savings here because the beads are much larger.
