The starting point – Compressed air is a valuable asset

Compressed air is absolutely necessary in many applications to deliver the required performance, making its use often unavoidable. Unfortunately, in most compressed air systems, less than 15% of the electrical energy used is actually available as useful energy in the form of compressed air for the respective application. In other words, more than 85% of the energy used is lost.

Compressed air is a valuable form of energy because it is produced with considerable effort, starting from the creation of the necessary infrastructure, through the costs of electrical energy, to maintenance costs. Every leakage and thus the unintentional loss of already produced compressed air from pipes and connections costs money.

The project – Making the automatic processing of blind rivets more efficient

It was worthwhile to thoroughly examine the proven and reliable GAV automatic riveting machine, which is in use in many small and large industrial companies worldwide, to find potential savings. Ideas were gathered and tested in CFD simulations and empirical tests.

The result - improved technology

Through numerous system modifications and the resulting customised setup, air consumption was reduced by up to 24%. Despite the reduced demand for compressed air, the performance of the GESIPA® Blind Riveting Machine could even be increased under certain conditions.

Considerable progress has also been made in the area of mandrel removal with the facelift of the automatable blind riveting machine. These modifications have generated a significantly stronger vacuum, which, among other things, has also made it possible to increase the previous maximum length of the hose package from 5 meters to up to 8 meters.

And that's new:

• Depending on the blind rivets processed, compressed air savings of up to 24% are possible.
• Less compressed air needs to be generated to operate the GAV.
• Due to the reduced consumption, there are fewer fluctuations in the customer's compressed air network.
• The possibility of using longer hose packages significantly increases the flexibility of the GAV.
