When is it right to consider extrusion?

Picture1We are deliberately staying away from detailed tolerance information, for a number of reasons. Our experience is that fit and function is as important.

We regularly achieve significantly tighter tolerances than all our competitors, but where fit and function can be achieved through design ingenuity, that is the way we prefer to go.

So, what makes a section extrusion friendly?

  • Correct choice of alloy and temper
  • Uniform wall thickness
  • Avoid sharp corners
  • Depth to width ratio of 3:1 this can be increased with the addition of large rads on the channel openings
  • Reduced number of internal chambers
  • External surface broken up

Check out our advice on the different ways to build additional features into the section geometry.
