December 2012 – Dürr will shortly be offering its customers a new software program for gluing systems. Final testing is currently in progress. The program will later be incorporated in automated systems used, for example, to glue body parts, windscreens or roof modules.
The control software enables the gluing process operations to be tested in advance in a simulation. Before a system is erected on the customer’s premises, the processes in all the components, such as the drum pump, heaters and, in future, dosing feeder and gun are replicated. Different variants of parameters such as the pressure, temperature and regulator settings as specified by the customer can be tried out to determine the best figures in advance.
Thanks to these results, the Dürr employees who subsequently install the system at the production location need only focus on fine-tuning the settings. This in turn reduces the time needed for commissioning and thus also the costs. Hitherto, simulation has mainly been used in the paint application field; now Dürr is extending its use.
Trials are currently being conducted in the Sealing Test Centre in Bietigheim. After these tests relating to material supply, the software will be put into operation by customers in the early part of next year. The plan is to expand its application field to metering technology.
The new program will be used in an area which is becoming increasingly important. That is because there is a growing move towards gluing instead of welding in automotive production. Benefits of gluing:
- Body stiffness is increased.
- Comfort is increased as a result of damping.
- Costs can be reduced thanks to good automatability.
- New, lighter materials like carbon fibre are being used which cannot be welded.
A mid-range car requires some 5000 weld points, of which approx. 50% can be saved by gluing. This reduces the production costs per body by up to 70 euros.
