Ngokuqhelekileyo, isethi yokubumba yenziwe ngamacandelo amathathu: i-mold mold, i-mold pad kunye nomkhono wokubumba. Isikhunta esihle siqulunqwe ngebhanti esebenzayo, imela engenanto, i-deflector kunye nezinye iindawo. Icandelo ngalinye linomsebenzi walo. Oku kulandelayo yii-aluminiyam ngokutsha.Sazise umsebenzi wezi nxalenye.

①Ibhanti yokusebenza: Indawo yokusebenza yebhanti yokusebenza i-perpendicular kumphezulu womsebenzi wokubumba. Injongo kukulungisa ubungakanani beprofayili. Inde kakhulu okanye imfutshane kakhulu ayifaneleki. Uyilo lwebhanti yokusebenza kufuneka luthathele ingqalelo ukuhlukana kodonga lweprofayili, umgama ukusuka kwiziko kunye nenxalenye apho umngxuma wokufa uhlanganiswe yibhuloho ye-shunt, njl.

②Imela engenanto: Yeyona tshaneli iphambili yeeprofayile zealuminiyam. Lilungu lolwakhiwo oluxhaswa yi-cantilever ekupheleni kwe-outlet yebhanti yokusebenza komngxuma wokufa, enokuqinisekisa umgangatho weprofayili kunye nobomi benkonzo yokufa.

③Ipleyiti yeBaffle: Kufuneka kubekho inkqubo yotshintsho kwinkqubo ukusuka kwintonga yealuminiyam ukuya kwiprofayile. Ipleyiti ye-baffle inokunciphisa inani le-deformation kwaye idlale indima yokuguquka kwemilo.

④Umngxuma wokuqhekeka: Emva kokuba i-alloy ye-aluminium idlulile le nkqubo ingentla, iqala ukungena kumngxuma wokuqhekeka ukuqhubela phambili ukucacisa ubume becandelo kunye nobukhulu beprofayili.

⑤Undoqo wokungunda: Qinisekisa ubume kunye nobukhulu bomgodi ngaphakathi.

⑥Igumbi lokuwelda: Emva kokuba wonke umsebenzi wokulungiselela usendaweni, i-alloy ye-aluminiyam iqala ukungena kwigumbi le-welding kwinqanaba lokugqibela le-extrusion.
