The table below displays selected examples of extruded profiles with preferred design shapes. If you have extruded aluminum profiles need,please consult on [email protected] or whatsapp/ wechat+8618902844286.
Arrange hollows symmetrically, if possible. | |
Open screw channels show a better geometrical accuracy in relation to each other and give a longer life to the die. |
|
Peaks should be rounded (avoid filling problems; higher extrusion speed). | |
Narrow slits only if unavoidable, otherwise add spacers whereby the tolerances of the opening distance are considerably improved. |
|
Contours which are connected with an unfavourable flow of material reduce extrusion speed and induce tolerance problems (for the cross section as well as for straightness and torsion). |
|
The tolerances for polygonal formed open cross sections can be improved considerably by adding stiffeners or by designing a hollow section. |
|
Small geometries of a thick section are difficult to fill out with metal and sometimes cannot be extruded. |
|
Small appendices in connection with thick parts of a section are hard to fill with metal and sometimes cannot be extruded. |
|
Avoid too thin or too wide walls in hollow sections (problems with tolerances, increased waste since defect not repairable). Arrange supporting spacers. |
