Dhuumaha birta ah ee kululwaxaa loo isticmaalaa in wax soo saarka ee habka extrusion kulul si ay u soo saaraan tuubooyinka birta ah oo aan kala go 'lahayn.

Extrusion Hot waxaa si ballaaran loo isticmaalaa in wax soo saarka ee aluminium, copper iyo tuubooyinka kale ee biraha nonferrous iyo profiles.Extrusion Hot of steel wax soo saarka ee labada tuubooyinka gaarka ah iyo profiles, way adag tahay in la isticmaalo wax soo saarka ee extrusion qabow ama extrusion ee xarunta adag oo diiran godka (iyada oo dalool ama dalool indha la'aan) steel carbon iyo qaybaha birta alloy, sida Sida ul leh madax qaro weyn, foosto, weel, iwm. Extrusion kulul ee saxnaanta cabbirka iyo dhammaystirka dusha sare ee ka fiican qaybaha foornada kulul, laakiin weli waxay u baahan yihiin inay maraan qaybta dhammaystirka guud ama mashiinnada.

Farsamada kululaynta kulul waa nooc ka mid ah biraha ka sarreeya heerkulka recrystallisation ee extrusion, billet tube ka extrusion dhinta, si ay u helaan qaabka dhinta cross qaybta tuubooyinka habka samaynta.Habka extrusion kulul (laga bilaabo tuubada ilaa tube Arakawa), biilka tuubada waa qallafsanaan ka hooseeya saddexda ilaa xaalad cadaadis cadaadis ah.Tani kaliya ma xallin karto dhibaatada tuubooyinka birta ee yar-yar ee samaynta, laakiin sidoo kale waxay ka fogaan kartaa tuubooyinka gudaha iyo dibaddaba cilladaha dusha sare ee ay keento diiqada adag.Markaa habka qaabaynta kululaynta kulul ayaa si gaar ah ugu habboon dhammaan noocyada birta daawaha ah, ahama
