I-Datang ivelisa i-Extruded Fin Tubes eveliswa yinkqubo ebandayo ye-rotary extrusion.I-Extruded Fin yenziwe kwi-tube ye-aluminium yangaphandle kunye nobukhulu obukhulu bodonga, olulungelelaniswe phezu kombhobho wesiseko sangaphakathi.Iityhubhu ezimbini zityhalwa kwiiarbor ezintathu ezinediski ezijikelezayo ezicudisa okanye zikhuphe amaphiko e-aluminiyam phezulu nangaphandle kwemathiriyeli ye-muff kwimilo ejikelezayo kumsebenzi omnye.Inkqubo ye-extrusion iqinisa amaphiko kwaye ithintele ukudibanisa kweentsimbi ezingafaniyo kwingcambu.Umphandle ovezwayo wangaphandle yi-aluminiyam kwaye akukho zikhewu zincinci phakathi kwamaphiko asecaleni apho ukufuma kunokungena khona.Oku kuqinisekisa ukusebenza kakuhle okulindelekileyo xa usebenzisa indawo eyandisiweyo yokudlulisa ubushushu.Ngexesha lenkqubo yokucima i-tight mechanical bond yenziwa phakathi kwetyhubhu yangaphandle ye-aluminium ephothiweyo kunye ne-tube yesiseko sangaphakathi sesinyithi esifunekayo.
