Design Considerations
The following points
might be helpful for designer of products for extrusion:
- Limit the irregularities
of shape as much as the function of the part allows. Metal flows
less readily into narrow and irregular die sections, making
distortion and other quality problems more likely to occur.
- Many extrusion
shops and metals suppliers provide standard shapes that might
serve the designer. A good rule of thumb is to always use
standard cross sections when possible.
- Tolerances are advised
to be liberal enough to avoid secondary drawing operations, if
possible.
- With all metals,
and particularly with steel and less easily extruded metals,
it is recommended to avoid extreme changes in section
thickness.
