Three Core Technological Advantages
Each process directly addresses critical field-failure concerns from clients.
LWM Online Weld Monitoring — From Sampling to 100% Assurance
Multi-channel synchronized signals detect plasma radiation, reflected light, and temperature in real-time, establishing a unique digital signature for every weld path. Automated comparisons with master waveforms instantly flag under-penetration or power anomalies. Weld data is permanently linked to the component serial number for full traceability.
Client Value: Shifts quality control from random sampling to 100% continuous monitoring, backed by scientific data required for AI server and automotive-grade validation.
Vacuum Helium Leak Detection — Quantitative Leak Rates over Pass/Fail
Dual-chamber vacuum helium mass spectrometers achieve a fine sensitivity of 10⁻⁹ mbar·L/s, vastly outperforming water immersion bubble checks (10⁻³) and pressure drop methods (10⁻⁴). Our strict shipping acceptance criterion is set at ≤ 1×10⁻⁵ mbar·L/s. Every unit comes with its individual test curve and equipment calibration certificate, seamlessly mapping to your engineering specification limits.
Helium Leak Testing Operation — Full Vacuum Chamber Test (100% Inspected)
CNC Straightening — Guaranteeing Interference-Free 2,200 mm Assembly
Long manifolds inevitably distort due to laser welding thermal stress. Our CNC straightening center automatically applies closed-loop calibration based on 3D laser scanning deviation profiles. With a minimal adjustment stroke of 0.3 mm, straightness is brought back to < 0.5 mm/m, strictly complying with EIA 19" Rack installation standards.
Result: Guarantees smooth installation without mechanical binding, releases internal residual stress concentrations, and logs comprehensive dimensional tracking into our factory MES.
