Izimbobo ezincane ezingavamile ezibonakala ekukhanyeni ebusweni be-aluminium foil zibizwa ngokuthi ama-pinholes. Njengoba ukushuba kuncipha, inani lamaphinifa liyakhula, okungenye yeziphambeko eziyinhloko zezinto ze-foil.

Uthuli ku-billet, emqulwini, emafutheni aginqikayo, futhi ngisho emoyeni ifinyelela ubukhulu mayelana 6 μm bese ingena igebe le-roll, okuzodala ama-pinholes. Ngakho-ke, akunakwenzeka nge-65m i-aluminium foil ukungabi namaphinikhodi. Kungahlolwa kuphela ngokuthi kungakanani kanye nosayizi.

Ngokuthuthukiswa komthamo ofakiwe wemishini ye-aluminium foil, izimo ze-aluminium foil rolling ziyathuthukiswa, ikakhulukazi ukuhlunga okusebenzayo kokuvimbela uthuli kanye namafutha aginqikayo kanye nokusethwa kwesistimu yokushintsha amaroli asheshayo, ukuze inombolo nosayizi wamaphinikhodi ebhokisini le-aluminium kuncike kakhulu kukhwalithi ye-metallurgical kanye nokukhubazeka komshini we-billet.

Njengoba imbobo yephini ngokuvamile iwukuchithwa kwesici esingenalutho, kunzima ukuthola ubudlelwano obuhambisanayo nesici sokuqala. Ngokuvamile kunenkolelo yokuthi ama-pinholes ahlobene kakhulu nokuqukethwe kwegesi, okufakiwe, inhlanganisela nokuhlukaniswa kwengxenye.

Ukuthatha ngempumelelo aluminium liquid purification, ukuhlunga, kanye nokucwengwa okusanhlamvu kungasiza ekunciphiseni izimbobo zokukhonkwane.

Ukuthuthukisa izakhiwo eziqinile zezinto, njenge-alloying, kungasiza futhi ekunciphiseni ama-pinholes. Izikhonkwane zefoyili ye-aluminium engu-6μm egoqwe izikhala zephinikhodi yekhwalithi ephezulu zingaba ngaphansi kuka-100/m². Kwinqubo yokugoqa ye-aluminium foil, kukhona ezinye izici eziningi ezibangela ama-pinholes, okungaba yinhlekelele. Izinkulungwane zamaphinifa ngemitha yesikwele azivamile. Qinisa ukuhlunga kwamafutha aginqikayo.

Ukushintshwa kwesikhashana kwemiqulu kanye nezinyathelo zokuvikela uthuli yizimo ezidingekayo ukuze kuncishiswe izimbobo kucwecwe lwe-aluminium; ukusebenzisa amandla amakhulu okugoqa kanye nokugoqana kwe-tension encane nakho kuzosiza ekunciphiseni ama-pinholes.
