Up to 40,000 wheels per hour can be tested with our over 200 machines for aluminum wheels delivered worldwide

We developed a fully automatic machine for leak testing of aluminum wheels for the automotive applications. The mass spectrometer test with test gas is used as measurement method. The test gas helium is recovered with a fully automatic recovery system. Our leak testers are used by all leading wheel manufacturers to meet the high quality requirements of the automotive OEM industry.

The test object is the actual aluminum rim. It is tested if the rim is capable of air-tightening the tire, which is put onto the rim later. We simulate the tire with our special sealing tools in our testing device and measure the test gas flow coming through the test piece (the rim). For this, the test gas is admitted to the outside of the rim and a vacuum is created within the rim.
