O vaega fa'apipi'i sima ose fa'aupuga lautele o foliga lavelave eseese o vaega sima.Ia faia i le maualuga-mama paʻu sima, o vaega sima e faia e ala i le oomi mago po o le malulu isostatic oomi, ma sintered i lalo o le vevela maualuga, ona saʻo machined.E faʻaaogaina lautele i masini semiconductor, fesoʻotaʻiga mataʻutia, laser, mea faʻafomaʻi, suauʻu, metallurgy, alamanuia faʻaeletoroni ma ona foliga e pei o le maualuga o le vevela, teteʻe o le corrosion, teteʻe abrasion ma le insulation.
