I-Datang ikhiqiza ama-Extruded Fin Tubes akhiqizwa inqubo ebandayo ye-rotary extrusion.I-Extruded Fin yenziwa ngeshubhu ye-aluminium yangaphandle enogqinsi olukhulu lodonga, oluqondaniswe phezu kweshubhu lesisekelo sangaphakathi.La mashubhu amabili aphushwa ezingosini ezintathu ezinamadiski azungezayo akhama ngokoqobo noma akhiphe amaphiko e-aluminium phezulu nangaphandle kwempahla ye-muff ngendlela ezungezayo ekusebenzeni okukodwa.Inqubo ye-extrusion iqinisa amaphiko futhi ivimbele ukuthintana kwensimbi okungafani empandeni yamaphiko.Indawo engaphandle eveziwe iyi-aluminium futhi azikho izikhala emizuzwini phakathi kwamaphiko aseduze lapho umswakama ungangena khona.Lokhu kuqinisekisa ukusebenza kahle okuhle okulindelekile lapho kusetshenziswa indawo enwetshiwe yokudlulisa ukushisa.Phakathi nenqubo yokuphothula isibopho esiqinile semishini yenziwa phakathi kweshubhu yangaphandle ye-aluminium ecijile kanye neshubhu lesisekelo sangaphakathi sensimbi edingekayo.
