Application of Helium Leak Detection on Aluminum Alloy Wheels

Purpose: The aluminum wheel is cast, and blisters may appear during the casting process, which is difficult to see with the naked eye. At present, most of the vacuum tires are used. If the air tightness test is not done, then if there are blisters, it is easy to leak after the tire is installed. If the car is driving at high speed, there is a safety hazard.
