Fa'asinomaga uamea vaega tusi loloto

Faatasi ai ma le atinaʻeina o sosaiete, ua faʻalauteleina vaega faʻailoga i pisinisi eseese, ma o vaega faʻailoga e mafai ona vaʻaia i soo se mea i le olaga i aso faisoo. E tele ituaiga o fa'ailoga tusi, e fa'aaogaina i so'o se tulaga o le olaga, mauamea vaega tusi loloto o se tasi oi latou. Uameaata lolotofa'ailogao le faʻaaogaina lea o se masini faʻailoga e faʻaleagaina ai mea uʻamea faʻapipiʻi ipu i le cylindrical, rectangular, trapezoidal, spherical ma conical vaega e ala i le faʻaogaina o le tosoina o mama poʻo molds uʻamea. Afai e tu'ufa'atasia ma isi faiga fa'ailoga, e mafai fo'i ona gaosia vaega e sili atu ona lavelave ma sa'o. E masani lava, o le ductility o uʻamea o le a aafia tuusaʻo le lelei o le gaosiga ma le lelei o le loloto ata, o lea e masani ona faʻaaogaina paʻu uʻamea e fai ma mea mata mo le faailogaina. O le loloto tusi ataingvaegasfa'agasologa ose faiga fa'apena fa'apitoa ona e fa'asaoina alagaoa. O mea masani faʻamalosi e aofia ai alumini alumini, sila, zinc, kopa ma isi metala.
