Cabra Design has developed a specific machine for testing the leakage level of alloy wheels with vacuum chamber techonology, called HLTW MACHINE. In particular, this new generation of machine is able to recovery helium without getting down the productivity.

Summary

The HTLW MACHINE can be provided in 6 different versions.

The technology developed by Cabra Design and included in all the machine range permits the highest helium recovery.

Over the technical advantages, the cost associated to helium management is extremely low.
