Friction Stir Welded Cold Plates
High-integrity, all-aluminium cold plates with no interface resistance.
Fully sealed, custom machined coolant path gives excellent thermal performance.
The product range
A closer look at the materials we supply.
Water channel substrate and matching lid are CNC machined, then friction stir welded into a fully sealed cold plate.
Flow paths tailored to component layout, with machined fins added inside the channel to boost surface area.
Post-weld CNC machining brings mounting faces and interfaces to final tolerance for direct assembly.
Every FSW cold plate is pressure and leak tested before dispatch to guarantee long-term integrity.
Ideal for EV inverters, battery cooling and high-power industrial systems where reliability is critical.
All-aluminium build
Lightweight, corrosion-resistant construction well suited to EV coolant loops.
Solid-state weld
No filler material, no porosity — a hermetic joint with excellent fatigue life.
Optimised flow channels
Machined flow paths tailored to your component layout for the lowest thermal resistance.
High pressure capable
Suitable for elevated coolant pressures and long-life duty cycles.
Volume-ready
A mature, repeatable process well suited to series production.
Design support
We can build to print or help with design through CFD-guided flow-path and thermal modelling.
