In the past, automobile manufacturers only required basic forms of leak testing to check standard subassemblies, such as, air conditioning, power train and cooling system components. Traditional hard-vacuum and accumulation methods were—and still are—used to test components such as radiators, evaporators, condensers, air-conditioner hoses, torque converters and valve bodies.
If someone tells you his leak test system is superior because of its control software, kick the tires, so to speak. In many, if not most, applications, it is the hardware, not the software, that makes or breaks the ability to get high throughput without compromising gauge R&R.
This white paper is for mechanical engineers, quality engineers, management and those whose goal is to detect leaks, avoid unnecessary production cost and anticipate process adjustments for maximum yield.
