Design Considerations for Aluminium Extruded Profiles
As Aluminium extrusions and machined profiles are becoming more popular to use as a material, there are many design considerations.
Large variations in wall thickness on an extruded section can often casue issues and needs to be managed carefully in the design. An initial consultation will go a long way to minimise potential later issues and provide a more robust product.
Although a wide variety of aluminium shapes can be extruded,
some factors need to be taken into consideration.
Sharp or Rounded Corners
Generally all corners are rounded, have a radii. Sharp corners should be avoided or minimised.
All extrusions need to take tolerances into account at the design stage. This may help improved fit of things like mating parts for instance.
Capalex conform to standard tolerances on design & form supplied to BSEN 755. Standard material composition supplied to BSEN 573. There are other standards in existance, these can be discussed during the initial consultation and design stage.
Some specific design criteria that may need to be considered are as follows.
Solid or Hollow Profiles
