1, lafoina: o le faʻafefeteina lea o le uamea i totonu o se vai e fetaui ma manaʻoga ma lafo i totonu o le faʻamalo, pe a maeʻa le faʻamafanafanaina ma le faʻamalosia, faʻamamaina togafitiga e maua ai se foliga faʻatulagaina, tele ma le faʻatinoga o le faʻagasologa (vaega poʻo avanoa).Fa'atekonolosi fa'aonaponei o le gaosiga o masini fa'aonaponei.

2, lafo gaosiga o tau maualalo, mo foliga lavelave, aemaise lava i vaega gaogao lavelave, sili atu e mafai ona faaalia lona tamaoaiga;I le taimi lava e tasi, o loʻo i ai le tele o fetuunaiga ma sili atu ona lelei mea faʻainisinia.

3, ae lafo le gaosiga o mea e manaʻomia (e pei o uʻamea, laupapa, suauʻu, mea faʻapipiʻi, ma isi) ma meafaigaluega (e pei o le ogaumu uʻamea, masini faʻafefiloi oneone, masini faʻapipiʻi, masini faʻapipiʻi, masini paʻu oneone, masini faʻafefe, lafo. ipu uʻamea, ma isi) sili atu, ma o le a maua ai le pefu, kasa leaga ma le pisa ma le filogia o le siosiomaga.

4, lafo o se vave malamalama tagata o se uʻamea faagasologa faagasologa vevela, o le atinae o le lafo saoasaoa e matua televave, ua atiina ae nodular lafo uʻamea, malleable lafo uʻamea, ultra-maualalo carbon uamea stainless ma alumini kopa, alumini silicon, alumini alumini alumini. , titanium, u'amea faavae nickel ma isi mea u'amea lafo, ma se faiga fou mo le fa'aefuefu lafo u'amea fa'atupuina togafitiga.Ina ua uma le 50's, na aliali mai ai le susu susu faʻataʻitaʻiga maualuga o le mamafa, faʻataʻitaʻiga oneone faʻamaʻaina vailaʻau ma le faʻaogaina autu, faʻataʻitaʻiga le lelei o le mamafa ma isi tuʻuina faʻapitoa, faʻamama faʻamaʻaina fana ma isi tekinolosi fou.

5, o loʻo i ai le tele o ituaiga o lafo, e tusa ai ma le auala faʻataʻitaʻiga e masani ona vaevaeina i: (1) oneone masani, e aofia ai oneone susu, oneone matutu ma vailaʻau faʻamaʻaʻaina oneone ituaiga 3. ② Tuʻu faʻapitoa, Lomiga mea faʻapipiʻi ma mafai ona vaevaeina. i totonu o le oneone minerale faanatura e pei o le mea autu faʻapipiʻi faʻapitoa faʻapipiʻi (faʻataʻitaʻiga, faʻapipiʻiina o tupe, faʻapipiʻiina o mea, faʻameamea faʻapipiʻi, faʻamalo le lelei, faʻafefe, faʻameamea, ma isi) ma uʻamea e avea ma mea faʻapipiʻi autu o le faʻailoga faapitoa ( e pei o le u'amea u'amea, fa'aoso fa'aoso, fa'aauau le fa'asolo, fa'alalo o le fa'aulu, fa'aulu centrifugal, ma isi).

6, lafo faagasologa e masani lava e aofia ai: (1) lafo (koneteina) faia uʻamea vai uʻamea malo lafo, lafo e tusa ai ma mea e mafai ona vaevaeina i le oneone, uʻamea, sima, palapala, graphite, ma isi, e mafai ona vaevaeina e ala i le faaaogaina lafoai, ituaiga semi-maumau ma tumau, lelei sauniuniga mold o mea autu ia e aʻafia ai le lelei o le tuʻuina atu;(2) o le fa'afefeteina ma le fa'ameamea o le u'amea, fa'ameamea (fa'ameamea) e tele lava ina lafo le u'amea, u'amea lafo ma fa'amea e le fa'amea;Tu'u togafitiga ma asiasiga, lafo togafitiga e aofia ai le aveesea o le autu ma lafo luga tino mai fafo, aveesea o le sasaa riser, suo olo burr ma su'isu'i ma isi protrusions ma vevela togafitiga, palasitika, ele togafitiga ma faiga faigata.Alavai pamu i totonu

Nortech o se tasi o taʻutaʻua fale gaosi oloa gaosi oloa i Saina ma faʻamaonia lelei ISO9001.
