Umbhobho wentsimbi eshushu eyongezelelweyoisetyenziselwa ukuveliswa kwenkqubo eshushu ye-extrusion ukwenza iityhubhu zentsimbi ezingenamthungo.

I-extrusion eshushu isetyenziswa ngokubanzi kwimveliso ye-aluminiyam, ubhedu kunye neminye imibhobho yesinyithi kunye neeprofayili ezingenayo.I-extrusion eshushu yentsimbi yokuvelisa zombini imibhobho ekhethekileyo kunye neeprofayili, kunzima ukuyisebenzisela ukuveliswa kwe-extrusion ebandayo okanye i-extrusion yeziko eliqinileyo nelifudumeleyo lomngxuma (ngomngxuma okanye umngxuma oyimfama) intsimbi yekhabhoni kunye neenxalenye zentsimbi yealloyi, ezifana njengentonga enentloko eshinyeneyo, umphanda, izikhongozeli, njl. njl.

iteknoloji eshushu extrusion luhlobo lwentsimbi ngaphezu ubushushu recrystallization of extrusion, billet ityhubhu ukusuka extrusion die, ukuze ufumane imilo icandelo cross umbhobho umbhobho metal ukwenza indlela yokwenza.Kwinkqubo ye-extrusion eshushu (ukusuka kumbhobho ukuya kwi-tube ye-arakawa), i-tube billet i-deformation phantsi kwezintathu ukuya kwimeko yoxinzelelo loxinzelelo.Oku akunako kuphela ukusombulula ingxaki yokwenziwa kombhobho wensimbi ongenakuguquguquka, kodwa kunokuphepha iityhubhu ngaphakathi nangaphandle kweziphene ezibangelwa kuxinzelelo lwe-tensile.Ke indlela yokubumba eshushu ye-extrusion ifaneleka ngakumbi kuzo zonke iintlobo zentsimbi yealloy, engenasici
