Product Overview
Aluminum heat sink profile production at Ruhai starts from your section drawing: send the PDF or DXF and we extrude the exact profile with fins, bores and mounting features in one piece.
Shown here is a 213.86×51.5 mm chassis heat sink profile with integrated fins and cable channel — one extrusion replacing an assembly of plate, fins and fasteners. New dies are cut in 10-15 days.
