I-Aluminium extrusion iyindlela esetshenziswa ukuguqula ingxubevange ye-aluminium ibe izinto ezinephrofayili ecacile ye-cross-sectional yokusetshenziswa okubanzi.Inqubo ye-extrusion yenza ngokugcwele inhlanganisela eyingqayizivele ye-aluminium yezici zomzimba.Ukusebenziseka kwayo kalula kuyivumela ukuthi yenziwe ngomshini kalula futhi isakazwe, kanti nokho i-aluminium iyingxenye eyodwa kwezintathu yokuminyana nokuqina kwensimbi ukuze imikhiqizo ewumphumela inikeze amandla nokuzinza, ikakhulukazi uma ihlanganiswe nezinye izinsimbi.
