"O la matou 40,000 sikuea mita fale o loʻo iai agavaʻa e faʻafetaui uma au punaʻoa le aluminium, ipu faʻailoga, manaʻomia stamping manaʻomia faʻatasi ai ma le tele o gaosiga filifiliga e gaosia maualuga-lelei oloa fofo. ”

E ui lava o le tele o metala paʻepaʻe uʻamea filogia castings mafai ona faʻaaogaina i le as-lafo tulaga, luga togafitiga e manaʻomia i nisi tulaga e puipuia ai le castings mai pala i le tasi lima, ma faia foi se teuteuina matafaioi i le isi lima ina ia faia foliga foliga sili atu matagofie.
O le faʻalauiloaina atu o metala paʻepaʻe metala paʻepaʻe castings oti:
Tasi. O a mea autu e fai ai togafitiga i luga ole metala paʻepaʻe?
①Plating: O le metala paʻepaʻe uʻamea filogia castings na faʻatoa faʻamamaina foliga pei chromium plated. Castings uʻamea filogia metala paʻepaʻe mafai foi ona tuusao plated ma chromium. E mafai ona faʻateleina le faigata ma faʻaaoga le teteʻe i le faʻaiʻuga, faʻaititia le vavaeʻeseʻesega ma faʻaleleia le pala.
②Painting: metala paʻepaʻe uʻamea filogia mafai ufiufi ma vali eseese. Mo nisi taugofie vaega, acrylic vali ma vaivai adhesion ma acid faʻapipiʻi vaega mafai ona faʻaaogaina. Mo vaega e manaʻomia maualuga teteʻe tetee, e sili ai le faʻaaoga epoxy resin vali po o eseese amine-faʻavae vali, ma tao pe a maeʻa valivali.
③Metal spraying: O le metotia spraying metotia o le ofu o le pito i luga o le gaosia vaega ma se manifinifi uamea ata tifaga i lalo maualuga lagona gaogao. Uamea spraying mafai simulate le foliga mai o apamemea, siliva, 'apamemea, auro, ma isi O lenei gaioiga e tele lava faʻaaoga mo oti castings.
'Anodizing togafitiga: O le togafitiga faʻalelei o metala paʻepaʻe metala paʻepaʻe castings o loʻo faʻatinoina i le fofo togafitiga anodizing ma i le voltage e le sili atu i le 200V. Anodizing togafitiga e mafai ona faʻaleleia atili ai le pala faʻatamaʻiina o metala paʻepaʻe alloys.
Tulaga lua. e mafai e le uʻamea filogia alumini suia uʻamu uʻamea filogia
O le tali e leai. Talu ai o le faʻatinoina o le metala paʻepaʻe uʻamea filogia oti-lafoina e sili atu, e mafai ona oti-lafo vaega saʻo ma foliga faigata ma manifinifi puipui. O le laualuga o le castings e lamolemole ma le dimensional sao e maualuga. E i ai lelei compression tetee ma ofuina tetee. Metala paʻepaʻe uʻamea filogia oti-castings mafai ona taliaina lelei Ituaiga eseese o luga togafitiga (plating, spraying, valivali, ma isi)
I le faʻatusatusaina o mea uʻamea filogia e lua, o le a tatou iloa ai e le mafai e le uʻamea filogia alumini ona suia le metala paʻepaʻe, aua o le malosi, maaʻa ma le faʻatulagaina o metala paʻepaʻe e sili atu lona lelei na i lo le uʻamea filogia alumini.
Tolu. Faʻafefea ona iloa se metala paʻepaʻe lelei?
1. Maualuga mama, maualalo metala paʻepaʻe ingot le mama mea, faʻavae i luga-maualuga mama metala paʻepaʻe mea mata. Ia
2. Maualuga faʻaliusuavai manatu: O le liusuavai vaega o se uʻamea filogia metala paʻepaʻe lelei e faʻatonutonuina i le 380-390 ° C.
3. Laʻititi metalaʻamu metala paʻepaʻe: e itiiti ifo le metala paʻepaʻe e maua pe a liusuavai.
4. Tipi ese e vaai le vaega. Afai o le vaega e sili atu maaleale, e masani lava sili atu.
