Discover how HeJin dual chamber vacuum helium leak testers detect micro leaks, prevent air spring safety hazards, optimize mass production & meet OEM quality standards.
Automotive air springs are core components of vehicle air suspension systems. Even tiny micro leaks—undetectable by conventional methods—cause gradual air pressure loss. Early signs include uneven body height, unstable driving, vibration, and reduced comfort and handling.
Worsening leaks disable height adjustment, reduce steering stability, lengthen braking distance, and cause body tilt and abnormal noise. Long-term low pressure accelerates wear of rubber bellows and seals, shortening the suspension’s service life.
In severe cases, sudden high-speed leaks can cause chassis collapse and loss of control, leading to accidents. Unqualified air springs also increase after-sales costs, damage brand reputation, and fail OEM inspections.
Traditional pressure decay testing misses these micro leaks. High-precision vacuum helium leak detection is therefore the most reliable quality control process for modern air spring production.
Compared to pressure decay testing, helium leak detectors offer far higher sensitivity, capturing subtle defects without damaging air springs.
Stable, repeatable data and full traceability meet ISO and SAE standards, making them trusted by global auto parts manufacturers and Tier 1 suppliers.
HeJin’s dual-chamber design uses alternate testing to shorten cycle times and boost production line throughput.
With ultra-high sensitivity (≤1×10⁻⁶ mbar·L/s) and a built-in helium recovery system, it cuts operational costs. PLC touch screen control enables automatic testing, alarming, data storage, and 24/7 continuous operation.
It tests automotive air springs, suspension bellows, and pneumatic seals, complying with ISO 20485, ISO 16247, SAE J2655, and CE standards for OEM IQC, EOL QC, and R&D verification.
Custom quick-change fixtures fit multiple air spring models, and the equipment integrates seamlessly with automatic production lines.
As a professional original manufacturer of leak testing equipment, HeJin integrates R&D, customization, production, and full technical service.
We offer free pre-sales planning, on-site installation, training, long-term spare parts, and timely maintenance—eliminating usage worries and reducing quality risks.
High-quality air suspension relies on precise leak detection. HeJin’s dual-chamber tester controls quality from the source, reducing defects and enhancing competitiveness.
