I lenei tusiga matou te taumafai e faʻaalia nisi faʻamatalaga e uiga i le fuafuainatau o u'amea lafo i le mamafa. O le mea moni lava e lua tau o fa'amea u'amea mafa'amea uameae iai mea fa'apena e mafai ona filifili pe fia le tau, e pei o le lavelave o le fausaga o le lafo, lapo'a lafo, meafaitino ma le aofa'i o mana'oga i le masina po'o le tausaga.
I le tulaga lautele o le lafo uamea lafo i taimi uma tau maualuga atu nai lo uʻamea castings. O lenei mea e mafua mai i mea e lua. O mea uamea lafo e sili atu ona taugata, aemaise lava u'amea u'amea ma le uamea. Afai e manaʻomia e le au faʻatau mea faʻainisinia faʻapitoa e pei o le ofuina-tetee, vevela-tetee poʻo le anti-ele faʻatinoga, o vailaʻau faʻapitoa (e pei o Mn, Mo, Cr, Ni) e tatau ona faʻaopopo i totonu o le uʻamea uʻamea i le taimi o le lafo. O le mea moni, o le vevela togafitiga tempering, quenching, annealing, carburization po normalization e masani lava ona faia mo castings uamea e maua ai le manaoga masini.
O le isi mea e mafua ai ona sili atu le taugata o le tuʻuina atu o uʻamea. Faatusatusa i le uʻamea lafo uʻamea ma ductile lafo uʻamea, lea e lafo e masani lava e lafo oneone lanu meamata po o atigi faʻameamea, e tatau ona faia i taimi uma le castings uamea e ala i le mea ua taʻua o le faiga o le faʻapipiʻi faʻapitoa, e aofia ai tupe faʻafaigaluega (fa'agasologa ga'o leiloa), leiloa foam lafo, vacuum casting po o isi tekinolosi fou. O faiga fa'amea o lo'o ta'ua i luga e mafai ona fa'amautinoaina le sa'o o le fua, lelei o luga ma mea fa'ainisinia lelei. E tusa ai, o le a maualuga atu foi tau.
