Custom Friction Stir Welding (FSW) liquid cold plates are advanced thermal management components engineered for high-performance heat dissipation in demanding applications. Utilizing FSW technology ensures high-integrity, leak-free bonding of complex aluminum structures, making these cold plates ideal for long-term reliability under elevated thermal loads.

Custom FSW Liquid Cold Plates are widely used across industries requiring precise thermal management:
Electric Vehicle (EV) Battery Cooling Systems
Power Electronics: IGBT, MOSFET, inverter modules
Renewable Energy Systems: Solar inverters, wind turbines
Medical Imaging Devices: MRI, CT, and laser systems
High-Performance Computing (HPC) & Data Centers
Telecommunications Systems and Laser Equipment
