Dual Chamber Auto Air Spring Vacuum Helium Leak Tester, ≤1×10⁻⁶mbar·L/s High

HeJin dual‑chamber automotive air spring vacuum helium leak testing equipment delivers ultra‑sensitive, fast, repeatable non‑destructive leak detection for air suspension components, fully compliant with ISO & automotive OEM standards, supported by direct factory supply and full lifecycle after‑sales service.

In the automotive industry, “close enough" isn’t an option. An air spring failure isn’t just a technical glitch; it’s a compromise on passenger comfort and vehicle safety. At HeJin, we understand the weight of that responsibility.

Our Dual-Chamber Automotive Air Spring Helium Leak Testing Equipment is more than just a machine; it is a sentinel for your production line. By utilizing advanced helium mass spectrometry, we help manufacturers transition from "hopeful quality" to "proven integrity." This system is engineered to handle the fast-paced environment of automotive manufacturing while maintaining the delicate precision required to find leaks invisible to the naked eye.

• 1.Why choose helium leak testing over pressure decay?

  Helium testing is 100–1000* more sensitive for micro‑leaks, faster, and more repeatable, meeting strict OEM standards.

• 2.Can this machine test different air spring models?

  Yes. We provide customized or quick‑change fixtures for multiple product types.

• 3.Is helium consumption high?

  No. The built‑in recovery system greatly reduces usage and long‑term cost.

• 4.Can it be integrated into an automatic production line?

  Yes, with standard communication interfaces for inline automation.

• 5.What is the typical test cycle time?

  Approx. 30–90 seconds, adjustable based on product size and process.

• 6.Is testing destructive to air springs?

  No, it is non-destructive and maintains part performance and appearance.
