Dual Chamber Auto Air Spring Vacuum Helium Leak Tester, ≤1×10⁻⁶mbar·L/s High Precision Device With Helium Recovery For OEM Suspension Quality Control

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.
