Tube Finning

Extruded fin is formed from an outer aluminum tube with a large wall thickness (muff), which is aligned over an inner base tube.

The two tubes are pushed through three arbors with rotating discs that literally squeeze or extrude the aluminum fins up and out of the muff material in a spiral shape in one operation.

Applied Fintube

The McElroy applied tube finning machine is a miniature high speed rolling mill synchronized with the rotation and advance of the tube. Quick change, steady rest input and output racks, allow the tube to rotate at up to 3000 RPM for 1" tube. Strip is fed to the machine from a payoff table beneath the Bare Tube Rack or from a free standing oscillating coil payoff system.
