Beyond the specifications, the key difference is support. Cooling-Thermal designs, builds, and services every machine in-house from our Kunshan factory — the same team that has delivered complete heat pipe production lines to Foxconn, Nidec, and Furukawa Electric is behind every automatic welder we ship.

Automatic Feeding

Copper tubes (D3-D8, lengths 70-500mm) are loaded into the feeding system. The machine automatically sorts, orients, and feeds each tube into position — no manual loading required, maintaining a consistent cycle at up to 550 pieces per hour.

Positioning & Clamping

Each tube is automatically positioned and clamped to the precise sealing length. Servo motor control ensures dimensional repeatability across every piece, keeping wall thickness tolerance within 0.1-0.3mm throughout continuous production runs.

Automated Welding

The 4kW motor drives the welding cycle, delivering stable, controlled weld energy to the degassing end of the tube. The result is a permanent, airtight seal with consistent surface finish — critical for downstream vacuum retention and heat pipe longevity.

Since 2017, CoolingThermal has specialized in R&D and manufacturing of high-precision automation equipment for heat pipe and vapor chamber (VC) production. Based in Kunshan, China, we offer integrated "one-stop" solutions—from custom design to on-site commissioning—leveraging advanced robotics and PLC systems to ensure high-capacity, stable manufacturing. Our proven expertise is backed by the successful delivery of dozens of automated production lines for global leaders like Foxconn, Nidec, and TIANMAI, with a strong export presence in Japan, South Korea, India, and Turkey.

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 pipe diameter and wall thickness can your automatic welder handle?

Our automatic welder supports pipe diameters from D3 to D8 and pipe lengths from 70 to 500mm. Wall thickness compatibility ranges from 0.1 to 0.3mm, making it suitable for standard thin-wall copper heat pipe welding applications across most production specifications.

What is the production capacity of the automatic welder?

The automatic welder delivers up to 550 pieces per hour under standard operating conditions. Actual output may vary depending on pipe specifications, weld parameters, and line configuration. Our engineering team can advise on expected throughput based on your specific tube diameter and production requirements.

Do you support custom welding machine configurations for non-standard pipe specifications?

Yes. We provide OEM/ODM equipment customisation. If your pipe diameter, wall thickness, length, or welding process requirements fall outside our standard specification range, our engineering team can adjust the machine configuration accordingly — including electrode design, feeding mechanism, weld parameter settings, and integration with upstream or downstream equipment on your production line.

Can I test the welder with my own pipe samples before placing an order?

Yes. We support sample testing before order confirmation. You can send your pipe samples to our facility and we will run them on the automatic welder to verify weld quality, dimensional accuracy, and process compatibility. This ensures the machine configuration is confirmed before production begins.

What power supply configurations does the machine support?

The automatic welder is compatible with 380V, 220V, and 415V power supplies, making it suitable for deployment in production facilities across different countries and regional electrical standards — including markets in Asia, Europe, and the Middle East — without requiring additional power conversion equipment.

Learn More About the Automatic Welder for Heat Pipe Production

Whether you are sourcing an automatic welder for a new heat pipe production line or looking to upgrade your existing welding equipment, understanding the key selection criteria behind heat pipe welding machine specifications will help you make a more confident purchasing decision.

An automatic welder is used in heat pipe manufacturing to seal the degassing end of copper tubes after vacuum processing. The quality of the weld — including seal integrity, dimensional consistency at the crimped end, and surface finish — directly affects the vacuum retention and long-term thermal performance of the finished heat pipe. Selecting the right automatic welding machine means matching the electrode type, feed mechanism, operating mode, and power configuration to your specific pipe diameter, wall thickness, production volume, and facility power supply.

Our automatic welder supports pipe diameters from D3 to D8, wall thicknesses from 0.1 to 0.3mm, and pipe lengths from 70 to 500mm, delivering up to 550 pieces per hour with a 4kW motor. The machine operates in both automatic and fully automatic modes and is compatible with 380V, 220V, and 415V power supplies — making it deployable across production facilities in Asia, Europe, and the Middle East without additional power infrastructure. With a compact footprint of 1,100 × 600 × 1,500mm and a total weight of 350kg, it is straightforward to position within an existing production floor layout.

The automatic welder can operate as a standalone heat pipe sealing unit or integrate directly into a complete heat pipe production line alongside pipe shrinking machines, powder filling equipment, vacuum degassing machines, water injection systems, bending machines, and thermal performance testing equipment — all available from Cooling-Thermal as a single-source automation partner.
