Aluminiyamu mbiri ali osiyanasiyana ntchito, koma chifukwa osiyana aloyi zikuchokera, kudzakhala kovuta kulamulira kutsirizitsa mu ndondomeko extrusion, motero kuchititsa dulness, mwa kafukufuku kuwala kwa zotayidwa mbiri mankhwala akhoza bwino atatu. mbali:
1. Aloyi zikuchokera chiŵerengero cha zinthu: kuonjezera zili mankhwala zinthu mkuwa ndi magnesium, chiŵerengero analimbikitsa ndi: Si0.55-0.65, Fe<0.17, Cu0.3-0.35, Mg1.0-1.1.
2. Yang'anirani njira yotulutsira ndikuwongolera kutentha kwa chotulutsa chamtundu wa aluminiyamu.Ndibwino kuti kutentha kwa ndodo ya aluminiyamu kukhale 510-530 ℃ ndi kutentha kwa sitolo kukhala 530-550 ℃.
3. Sinthani pretreatment ndondomeko dyeing anodic makutidwe ndi okosijeni, pickling mafuta chabe mbiri aluminiyamu, osati dzimbiri alkali.
Ndemanga:
Kupaka mbiri ya aluminiyamu nthawi zambiri kumakhala zokutira ndi utoto.
Kuti mukhale wopepuka komanso wonyezimira:
1. Gwiritsani ntchito mfuti yopopera bwino, ndipo kuchuluka kwa ufa wopopera mbewu mankhwalawa, m'pamenenso chifunga chimakhala chabwinoko (monga ejection effect)
2. Kunyezimira kwakukulu (gloss 95 ndi pamwamba) ufa (mtundu wosankha) kapena penti ndi utoto wabwino wa fluorocarbon
