Custom FSW Liquid Cold Plate

Custom Friction Stir Welding (FSW) Liquid Cold Plates are advanced thermal management components designed for high-efficiency heat dissipation in demanding electronic, automotive, and power equipment environments. Leveraging FSW technology ensures leak-free, high-integrity bonding of complex aluminum structures, making these cold plates ideal for long-term reliability under high thermal loads.

Applications include:

• Electric vehicle battery cooling systems

• Power electronics (IGBT, MOSFET, inverter modules)

• Renewable energy systems (solar inverters, wind turbines)

• Medical imaging devices

• High-performance computing (HPC), data centers

• Laser equipment and telecommunications systems

Customer FAQs

Q1: Can I customize the internal channel layout?
Yes, we support fully custom channel path design to match your thermal requirements and flow rates. You can provide CAD files or we can assist with thermal simulations.

Q2: What’s the typical lead time?
Prototype orders take 7–15 working days. Mass production depends on quantity and complexity—usually 3–5 weeks.

Q3: How do you ensure leak-proof welding?
We use FSW for strong, porosity-free joints and perform 100% helium leak tests per unit.

Q4: What file formats do you accept?
STEP, IGES, DWG, PDF, or 2D/3D drawings are all acceptable.

Q5: Are there any MOQ requirements?
We support low-volume prototypes (1–5 pcs) and high-volume production.
