High-Reliability 1P104S Aluminum Cold Plate with Helium Leak Testing for ESS Applications
We are a dedicated manufacturer of battery pack heat exchangers, employing cutting-edge stamping technology combined with vacuum brazing to produce high-performance liquid-cooled cold plates.
Our company specializes in designing, manufacturing, and delivering thermal management solutions for battery packs that use cylindrical, prismatic, or pouch cells. This specific product series showcases our stamped and vacuum-brazed aluminum cold plates, which combine the economic benefits of stamping with the outstanding joint strength and leak-tight reliability of vacuum brazing.
We offer a full range of cooling solutions for battery cells, including serpentine tubing for cylindrical types (18650, 21700), water-cooled plates for prismatic cells, and flow channel plates for pouch cells. Our stamped and brazed cold plates are ideally suited for high-volume manufacturing of prismatic and pouch cell battery modules.
We hope to apply our technical know-how to create a mutually beneficial long-term relationship with you, as proper battery thermal management is crucial for EV efficiency and safety. Here are some of our core competencies:
In-House Tooling Capability: We handle all tooling development internally, ensuring rapid and accurate first-article inspection for stamped parts.
Adaptable Custom Designs: We produce cold plates in a wide variety of stamped geometries to accommodate different battery pack configurations.
Technical Consultation: Our experienced engineering staff provides professional advice on design feasibility and performance optimization for new concepts.
Turnkey Service Package: Alongside heat exchangers, we also provide associated insulation materials and silicone thermal pads, offering a holistic thermal management solution.

Both 3003 and 3102 alloys exhibit excellent resistance to corrosion, making them widely adopted for heat exchange applications. For vacuum brazing processes, 3003 alloy with a braze cladding layer is the preferred material due to its ideal flow behavior during heating.

Q: Are you a trading firm or a factory?
A: We are a direct manufacturer with over ten years of hands-on experience in stamping, brazing, and thermal management solutions.
Q: What makes vacuum brazing better than other joining methods?
A: Vacuum brazing delivers clean, strong, and completely leak-free connections without any flux leftover. This makes it ideal for mission-critical applications like EV battery cooling.
Q: What payment terms do you offer?
A: Our standard terms are 30% T/T deposit in advance, with the remaining 70% settled prior to shipment.
Q: How long does sampling and mass production take?
A: Creating new molds and sending out free samples (within 5 kg) generally requires 15–20 days. After sample confirmation, mass production is normally completed in 25–30 days.
Q: Can you provide OEM/ODM services?
A: Absolutely! We offer full OEM and ODM services, covering custom stamping dies and specialized brazing parameters.
Q: Is it possible to get a sample for evaluation?
A: Of course! We are happy to provide samples so you can assess our quality firsthand.
Q: Do you accept small trial orders?
A: Yes, we accept pilot orders and can also assist with design modifications as needed.
