Reliable Leak Detection for High-Volume Relay Manufacturing
Every relay manufacturer faces the same challenge:
How can you ensure every ceramic housing leaving the production line is perfectly sealed?
A tiny leak may not be visible today, but months later it can cause moisture ingress, electrical instability, customer complaints, and costly warranty claims.
The HeJin Relay Ceramic Housing Helium Leak Testing Equipment helps manufacturers identify microscopic leakage before products reach the market.
With high-sensitivity helium mass spectrometry technology and intelligent automation, the system delivers accurate, repeatable, and efficient leak testing for modern production environments.
Whether you produce relays for industrial control systems, power equipment, communication devices, or electronic assemblies, sealing integrity directly impacts product reliability.
Our helium leak testing system allows you to:
As a professional manufacturer, HeJin develops and produces its own testing equipment.
No trading company.
No unnecessary communication delays.
Direct support from engineers who understand the machine.
Different relay housings require different testing solutions.
Our engineering team can customize:
to match your specific production needs.
The system is designed for long operating hours in industrial environments.
High-quality components from internationally recognized brands ensure:
Detect leak rates down to:
1*10⁻⁹ Pa·m³/s
Suitable for high-reliability electronic products requiring strict sealing verification.
