You can optimize your equipment and invest in new systems…
But if you don’t perform regular vacuum leak inspections, you may be letting money escape from your vacuum system every day without even realizing it.
Vacuum leaks – small, but deadly!
Many factories in Vietnam invest billions to tens of billions of VND in advanced vacuum coating machines and high-end heat treatment furnaces, yet they often overlook regular vacuum leak inspections, which can lead to serious consequences:
-
Vacuum pressure cannot reach the required level → unstable process performance
-
Longer pump-down time → extended production cycles
-
Higher pump load → increased power consumption and reduced equipment lifespan
-
Product defects → especially critical for vacuum coating and heat treatment applications
-
Toxic gas leakage (in some applications) → potential safety hazards
Even a 1 mm leak in a vacuum system can increase electricity costs by 20–30 million VND per month, not to mention the risks of equipment damage and large-scale product defects.
So how can leaks be detected quickly – accurately – and cleanly?
