Advantages of the Helium Leak Testing Machine
1.High-Temperature Resistance — Rated Up to 200°C
The machine is rated for applicable temperatures up to 200°C — significantly exceeding the operating temperature of most competing helium leak testers. This makes it suitable for testing thermal management components that undergo elevated-temperature processes before leak testing, including heat pipes and vapor chambers that have been through hot pressing, soldering, or thermal cycling steps in the production sequence.
2. Multi-Media Compatibility — Air, Steam & Water
Unlike conventional helium leak testers limited to air as the test medium, this machine supports air, steam, and water as applicable media — providing flexibility across different test protocols and product specifications without requiring separate equipment. This is particularly valuable for B2B customers whose thermal management solutions production lines handle multiple product types with different quality specification requirements.
3. Precise Pressure Control — 0.6 MPa Setting with ≤ 1.1x Emission Limit
The machine operates at a setting pressure of 0.6 MPa with a nominal force of PN 1.0 MPa, and the emission pressure is strictly controlled to no more than 1.1 times the set pressure. This tight pressure control prevents over-pressurisation damage to thin-wall heat pipe and vapor chamber components during the test cycle, ensuring that the leak testing process itself does not introduce defects into otherwise conforming units.
4. Industrial-Grade Build — 2,000 kg, Continuous Production Rated
Weighing 2,000 kg with an overall footprint of 1,650 x 1,700 x 1,900mm, the machine is built for continuous, high-cycle industrial production environments — not laboratory or sample-testing use. The heavy-duty construction ensures dimensional stability, vibration resistance, and long-term measurement accuracy under the conditions of a working heat pipe or thermal management solutions production line.
5. Factory-Direct Supply with OEM/ODM Customisation
thermalmachinery supplies the helium leak testing machine factory-direct from our Kunshan production facility, eliminating distributor markups and ensuring direct access to our engineering team for technical support, customisation discussions, and after-sales service. B2B procurement teams requiring modified specifications — different pressure ratings, chamber dimensions, or integration with specific upstream equipment — can discuss OEM/ODM configuration directly with our engineering team.

FAQ
What production throughput does the helium leak testing machine deliver?
The machine delivers 1,000 pieces per hour — the highest throughput in its class for heat pipe and vapor chamber leak testing. This makes it the appropriate choice for B2B procurement teams integrating helium leak detection directly into high-volume thermal management solutions production lines, where the leak tester must match or exceed the output of upstream sealing and degassing equipment without creating a bottleneck.
What test pressure and temperature range does the machine support?
The machine operates at a setting pressure of 0.6 MPa with a nominal force of PN 1.0 MPa. Emission pressure is automatically controlled to remain at or below 1.1 times the set pressure. The applicable temperature range is up to 200°C — allowing the machine to test thermal management components that have undergone high-temperature production processes such as hot pressing, soldering, or brazing prior to leak testing.
What test media does the machine support?
The machine supports air, steam, and water as applicable test media. This multi-media capability distinguishes it from conventional helium leak testers that are limited to air only — providing flexibility for B2B procurement teams whose production lines test components across different quality specifications and test protocols that require different media types.
Where does helium leak testing fit in the heat pipe production line?
The helium leak tester is positioned after all mechanical forming and sealing operations — including tube shrinking, bending, hot pressing, and automatic welding — and immediately before the final thermal performance testing step. This position ensures that all potential leakage points introduced by upstream mechanical processes are captured before the unit consumes thermal performance test capacity, maximising overall line efficiency and yield rate.
Can the machine be integrated into an existing production line, or does it require a dedicated setup?
The helium leak testing machine can be integrated into an existing heat pipe or vapor chamber production line. It can also be ordered together with our complete range of heat pipe production equipment — tube shrinking machines, vacuum sintering furnaces, degassing machines, automatic welders, pipe benders, and thermal performance testing machines — as a fully integrated thermal management solutions production line. Our engineering team will assess your facility layout, utility connections, and line configuration requirements before confirming the integration approach.
