1. Zosawotcha zamkati zamkati + zachitsulo ndi kuphatikiza koyenera kwa mphamvu, kusinthasintha, kukana moto, kukana chinyezi, kutsekereza kutentha, kutsekereza mawu ndi kukongoletsa.
2. Kuchita bwino kwamoto. Poyesa kuyaka, kufalikira kwa zero, kulibe halogen, utsi, utsi, poizoni, kudontha, kutulutsa ma radiation, ndi zina zambiri zatsimikizira ntchito yake yabwino kwambiri yachitetezo, ndipo ili ndi mawonekedwe oteteza chilengedwe chobiriwira.
3. Kukongoletsa kokongola kwambiri, zinthu zokongola komanso zokongola, kukana kwa dzimbiri, kukana kuipitsa, kupirira.
4. Kuphatikizika kwangwiro kwa mphamvu ndi kusinthasintha kumapangitsa kuti pakhale kusowa mphamvu kwa gulu la aluminiyamu. Itha kupangidwa ndi mawonekedwe a hyperbolic, osavuta kuyiyika ndikuwongolera.
Zomwe zimakulungidwa za A2 zimatulutsidwa kudzera mu unwinder, kenako zinthu zapakati zimatenthedwa kutentha kwambiri mu uvuni kuti mufewetse koyilo yapakatikati. Panthawi imeneyi, coil pachimake ndi plasticity. Zinthu zapakati zikadutsa mu uvuni, aluminiyamu yapamwamba ndi yotsika Khungu limatulutsidwa ndi makina opukutira a aluminiyamu, filimu yomatira imadutsa mu pre-composite roller, ndipo filimu yomatira imamangiriridwa pakhungu la aluminium, kenako zikopa za aluminiyamu zam'mwamba ndi zam'munsi zimadutsa muzitsulo zophatikizira kuti khungu la aluminiyamu ndi chigawo chapakati chigwirizane. Kutentha kwa makina kumatha kukhazikitsidwa mosiyana. Pambuyo kudutsa magulu angapo a pawiri mayunitsi, pambuyo mkulu-kutentha otentha lamination ndi extrusion, gulu ndi pasted ndi kupangidwa, ndiyeno utakhazikika ndi madzi utakhazikika mpweya bokosi, ndiyeno anadutsa wodzigudubuza mosanjikiza kumamatira filimu zomatira mwamphamvu. Panthawi imeneyi, bolodi imadulidwa. M'lifupi mwake atatsimikiziridwa, bolodilo limadutsa pa ng'oma yoyendetsa galimoto ndipo imafika pamakina ometa ubweya. Kumeta ubweya kumadula kutalika kokhazikika molingana ndi kutalika kwake. Pambuyo popanga bolodi lopangidwa, bolodi imasamutsidwa ku mphasa kudzera papulatifomu yotsitsa ndikutsitsa. Zounikidwa, ndipo pamapeto pake zidapakidwa pamanja ndikutumizidwa.
