Machined Aluminum Profile Part

Using extrusion as the blank is the practical compromise between cost and accuracy: the die holds the section, CNC holds length and hole positions, and far less material is removed than from a solid billet.

Where it fits

Long parts, standard sections, medium to high volume. For complex sections at low volume, a simple die can still make sense.

Watch-outs

Extrusions carry residual stress. Straighten or stress-relieve before milling to avoid bowing, and use soft jaws to prevent clamp marks.

Process notes

Profile cut to length, straightening or stress relief, CNC milling, drilling and tapping, deburring, anodizing, dimension sampling.

Applications

Machine guide rails, long brackets, panel frames, combined structural and thermal parts.
