Product Name: Long-Life Epoxy Insulated Aluminum Cooling Plate for 1P104S ESS Battery Modules
We are a specialized manufacturer of battery pack heat exchangers, utilizing advanced stamping combined with vacuum brazing technology to produce liquid-cooled cold plates.
Our company focuses on designing, manufacturing, and supplying thermal management solutions for battery packs using cylindrical, prismatic, or pouch cells. This particular product line highlights our stamped and vacuum-brazed aluminum cold plates, which offer the cost advantages of stamping along with the exceptional joint integrity and leak-proof performance of vacuum brazing.
We deliver comprehensive cooling solutions for battery cells, including serpentine tubes for cylindrical formats (18650, 21700), liquid cooling plates for prismatic cells, and channel plates for pouch cells. Our stamped and brazed cold plates are especially well-suited for high-volume production in prismatic and pouch cell battery modules.
We aim to leverage our technical expertise to build a lasting partnership with you, given that effective battery thermal management is essential for EV performance. Below are some of our key strengths:
(Table remains unchanged from original)
Both 3003 and 3102 alloys provide outstanding corrosion resistance, making them popular choices for heat exchange uses. For vacuum brazing, 3003 alloy with a brazing cladding layer is the top selection because of its superior flow properties during the brazing cycle.
(Table remains unchanged from original)
| Feature | Stamping + Vacuum Brazing | CNC Machining |
|---|---|---|
| Production Volume | High-volume, economical | Low-to-medium volume |
| Unit Cost (large quantity) | Highly competitive | Higher |
| Joint Strength | Superior (brazed connection) | N/A (single-piece) |
| Leak Tightness | Excellent (vacuum brazed) | Good |
| Design Flexibility | Moderate (die-limited) | High (fully adaptable) |
| Lead Time (initial sample) | 15–20 days (requires tooling) | 10–15 days (no tooling) |
Q: Are you a trading company or a manufacturer?
A: We are a manufacturer with more than a decade of experience in stamping, brazing, and thermal management systems.
Q: Why choose vacuum brazing over other joining techniques?
A: Vacuum brazing creates clean, robust, and leak-free joints without any flux residues. It is perfect for high-reliability applications such as EV battery cooling.
Q: What are your payment terms?
A: Typically, we ask for a 30% T/T deposit upfront, with the remaining balance due before shipment.
Q: What is the timeline for samples and mass production?
A: Developing new molds and providing free samples (up to 5 kg) usually takes 15–20 days. Once samples are approved, mass production is finished within 25–30 days.
Q: Do you offer OEM/ODM services?
A: Yes, absolutely! We provide full OEM and ODM capabilities, including custom stamping dies and tailored brazing specifications.
Q: Can I receive a sample for testing?
A: Certainly! We are glad to supply samples for your quality assessment.
Q: Is a small trial order possible?
A: Yes, we welcome sample orders and also offer design support as needed.
