How many types of extruded aluminum profiles

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.
