O le sini o le mea autu autu mo le sauniaina o ata manifinifi. I le taimi nei, o le faʻaaogaina masani o sauniuniga ma le faʻaogaina o metotia e aofia ai le faʻaaogaina o le paʻu o le metallurgy technology ma le tuʻufaʻatasia o le faʻafefeteina faʻafefeteina masani, aʻo matou faʻaaogaina le tekinolosi sili atu ona faʻaogaina ma fou fou.
O le sauniuniga o le nickel-chromium mea autu o le filifilia lea o le nickel ma le chromium o le mama eseese e pei o mea mata e tusa ai ma manaoga mama eseese o tagata faʻatau, ma faʻaogaina le ogaumu faʻafefete faʻafefe mo le faʻafefeteina. O le fa'agasologa o le fa'afefeteina e masani ona aofia ai le fa'ameamea i totonu o le potu fa'ameamea - ogaumu fufulu kasa argon - vacuum extraction - puipuiga o le kasa inert - fa'afefeteina fa'ameaalofa - fa'amamāina - fa'alili - fa'alili ma demoulding.
O le a matou faʻataʻitaʻiina le tuʻufaʻatasia o mea faʻapipiʻi, ma o mea e fetaui ma manaʻoga o le a faʻatautaia i le isi laasaga. Ona faia lea o le nickel-chromium ingot ma taʻavale ina ia maua ai se ipu faʻasalalau sili atu, ona faʻaogaina lea o le ipu faʻapipiʻi e tusa ai ma manaʻoga o le tagata faʻatau e maua ai le nickel-chromium sini e fetaui ma manaʻoga o le tagata faʻatau.
