Why Choose Hawkstein Helium Leak Testing Technology?

Ultra-Fine Tracer Sensitivity: Engineered specifically to leverage the small-molecule "search" characteristics of Helium gas, capturing microscopic structural flaws that pressure decay methods miss entirely.
Industrial-Grade Architecture: Housed in our standard 1800mm × 2000mm × 1600mm stable, heavy-duty industrial enclosure built to withstand continuous, high-throughput manufacturing floor environments.
PLC-Driven Traceability: Advanced PLC logic handles evacuation, helium charge, fine-leak sensing, and venting sequences automatically, logging unalterable test logs for regulatory tracking.

Strategic Applications

Aerospace & Defense: Validation of critical high-pressure fuel systems, emergency oxygen lines, cryo-valves, and strategic defense pressure components.
Automotive & EV Mobility: High-precision trace testing for EV battery enclosures, cooling plates, air conditioning components, and fuel delivery manifolds.
Industrial Manufacturing & Medical Devices: Leak integrity assurance for specialized high-pressure process valves, heat exchangers, and hermetically sealed medical or life-support apparatus.

FAQs

Because Helium molecules are exceptionally small, they can escape standard industrial seals. Hawkstein systems utilize ultra-precise, high-vacuum chambers, hard stainless steel piping, and specialized compound dynamic seals to completely isolate the tracer gas and direct it straight to the spectrometer.

Yes. To achieve high sensitivity (10^{-9} mbar L/s}), the component must be tightly integrated into a vacuum circuit. We custom-engineer fixture-based tooling for various component geometries to ensure repeatable, automated sealing.
