How it’s made – Wieland Microcool friction stir welded cold plate with MDT pin fin inside
We start with an aluminum extrusion or plate, from there we machine the pockets for the MDT pin fin plates, and fluid manifolds.
Then we friction stir weld the fin plates into the tub or manifold. After welding we fly cut the top to remove the FSW flash and create the flat and smooth cooling surface. As a last step we add all holes, any finish machining and then leak test the finished cold plate.
