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

Cooling-Thermal 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.

Production Line Position — Where Helium Leak Testing Fits in the Thermal Management Manufacturing Process

Production Step	Equipment
Tube forming	Automatic Shrinking Tube Machine (500 pcs/hr)
Powder filling	Copper Powder Filling Machine (4,000 pcs/hr)
Copper sintering	Vacuum Sintering Furnace (850-1000°C)
Water injection	Automatic Water Injection Machine
Vacuum degassing	Copper Heat Pipe Vacuum Degassing Machine (300 pcs/hr)
Tube sealing	Automatic Welder (550 pcs/hr)
Pipe shaping	Automatic Heat Pipe Bender (2D & 3D)
Flattening	Hot Press Machine
Leak testing	Helium Leak Testing Machine (1,000 pcs/hr)
Thermal performance testing	Automatic Performance Testing Machine (250 pcs/hr)

Why This Position in the Production Sequence Matters?

Placing helium leak testing after all mechanical operations — tube forming, bending, hot pressing, welding — ensures that every potential leakage point introduced by these processes is captured before the unit moves to thermal performance testing. Running leak testing after mechanical operations but before thermal performance testing prevents wasted test time on units that are already defective on an airtightness basis, improving the overall efficiency and yield rate of the production line.

At 1,000 pcs/hr, the helium leak tester's throughput exceeds that of the upstream automatic welder (550 pcs/hr) and downstream performance tester (250 pcs/hr) — ensuring it never becomes the rate-limiting step in the production line. This throughput margin also allows a single helium leak tester to serve multiple upstream production streams simultaneously, reducing the total equipment investment required for high-volume thermal management solutions manufacturing operations.

Honestly, communication was the biggest surprise. I sent a message and got a real, detailed reply within hours — not a template. They actually understood what I was asking.

We had a lot of technical questions before placing the order. They answered every single one — no pressure, no rush. By the time we signed, we already felt like we knew the team.

What I appreciated most was that they kept us updated throughout production without us having to chase. Regular photos, test results, shipping updates — everything was proactive.

I've worked with several Chinese equipment suppliers before. ThermalSolution is different — their English is solid, their engineers reply directly, and when there's a problem, they say so clearly instead of going quiet. That honesty matters a lot to us.

FAQs

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.

Learn More About Helium Leak Testing Machines for Thermal Management Solutions Manufacturing

A helium leak testing machine — also referred to as a helium leak tester, helium leak detector, or helium mass spectrometer leak tester — is the most sensitive and reliable method available for airtightness testing of sealed thermal management components including heat pipes, vapor chambers, and brazed heat sink assemblies. Compared to alternative methods such as pressure decay testing (which detects bulk pressure loss but cannot locate or quantify micro-leaks), bubble leak testing (limited by visual resolution and not suitable for production-line use), and air pressure testing (which cannot detect the micro-level defects that cause gradual vacuum loss in heat pipes), helium leak testing offers several order-of-magnitude improvements in detection sensitivity — making it the standard quality control method for high-reliability thermal management components.

The key selection criteria for a helium leak testing machine in thermal management solutions production are: throughput (units per hour, to match the upstream production line), test pressure (must exceed the product's operating pressure to detect marginal seals), temperature rating (must accommodate components that arrive hot from upstream processes), test media flexibility (air, steam, or water depending on the test protocol), and build quality (continuous production environments require industrial-grade construction, not laboratory equipment). The Cooling-Thermal machine delivers 1,000 pcs/hr, 0.6 MPa setting pressure, PN 1.0 MPa nominal force, ≤ 200°C temperature rating, multi-media support, and 2,000 kg industrial-grade construction — addressing all five criteria simultaneously.

Cooling-Thermal supplies helium leak testing machines as standalone quality control units for integration into existing production lines, or as part of complete thermal management solutions production line packages — alongside automatic performance testing machines, temperature difference testers, and the full range of heat pipe and vapor chamber manufacturing equipment.
