Friction Stir Welded Heat Sinks (Widths Over 200 mm)
ShunTeh’s friction stir welding technology breaks through the conventional width limitations of aluminum extrusion heat sinks without the need for additional tooling investment.
Combining aluminum extrusion with a patented friction stir welding process, ShunTeh can manufacture wide aluminum heat sinks with strong alloy bonding, excellent thermal conductivity, and reliable mechanical strength.
This technology enables the integration of large-scale heat dissipation fins for high-power applications, including industrial equipment, inverter systems, power electronics, and other demanding thermal management applications.
