1.Dab tsi yog fastener?
Fasteners yog ib chav kawm ntawm cov khoom siv tshuab dav siv rau kev sib txuas ceev. Ntau yam ntawm cov fasteners tuaj yeem pom ntawm ntau yam tshuab, khoom siv, tsheb, nkoj, kev tsheb nqaj hlau, txuas hniav, cov tsev, cov qauv, cov cuab yeej, cov cuab yeej, cov cuab yeej thiab cov khoom siv. Nws yog tus cwj pwm los ntawm ntau yam kev qhia tshwj xeeb, kev siv sib txawv, thiab tus qauv, serialized, universal hom degree kuj yog siab heev. Yog li ntawd, qee cov neeg hu ua cov txheej txheem hauv teb chaws uas twb muaj lawm ntawm cov fasteners raws li tus qauv fasteners, los yog yooj yim raws li cov qauv.
2.Fastener kev faib tawm
Nws feem ntau suav nrog 12 yam hauv qab no: bolts, studs, screws, ceev, tapping screws, ntoo screws, washers, nres, pins, rivets, sib dhos, thiab kev sib txuas khub, vuam pas nrig.
3.Tus qauv tseem ceeb rau fasteners
International Standard: ISO
National standard:
ANSI - Tebchaws Asmeskas
DIN - Lub teb chaws Yelemees sab hnub poob
BS - UA
JIS - Nyiv
AS - Australia
4.Fastener cov ntaub ntawv kev ua tau zoo yuav tsum tau
Cov khoom siv kho tshuab ntawm cov khoom muaj xws li ob yam: mechanical properties of material and mechanical properties of fasteners.
Mechanical zog ntawm cov ntaub ntawv: Ntawm ib sab yog kev siv cov khoom siv. Ntawm qhov tod tes yog cov txheej txheem kev ua haujlwm.
Cov khoom siv raws li kev txiav txim siab tshaj plaws yog: carbon steel, stainless hlau, stainless hlau, tooj liab, txhuas thiab lwm yam. Cov pa roj carbon steel kuj tseem muab faib ua cov pa roj carbon tsawg (xws li C1008 / C1010 / C1015 / C1018 / C1022), cov pa roj carbon nruab nrab (xws li C1035), siab carbon steel (C1045 / C1050), alloy steel (SCM435 / 10B21 / 40Cr) . General C1008 cov ntaub ntawv yog cov khoom qib zoo tib yam, xws li 4.8 ntsia hlau, cov txiv ntoo zoo tib yam; C1015 nrog lub nplhaib screws; C1018 nrog tshuab screws, nrog rau tus kheej tapping screws; C1022 feem ntau yog siv rau tus kheej tapping screws; C1035 nrog 8.8 ntsia hlau; C1045 / 10B21 / 40Cr nrog 10.9 screws; 40Cr / SCM435 nrog 12.9 ntsia hlau. Stainless hlau muaj SS302 / SS304 / SS316 ntau tshaj. Tau kawg, tam sim no kuj nrov ntau ntawm SS201 cov khoom, lossis txawm tias cov khoom siv nickel qis, peb hu cov khoom tsis muaj tseeb stainless hlau; cov tsos zoo li cov hlau tsis muaj steel, tab sis kev ua haujlwm tiv thaiv corrosion yog qhov sib txawv ntau.
5. Kev npaj nto
Kev kho deg yog txheej txheem ntawm kev tsim cov txheej txheej hauv cov khoom ua haujlwm los ntawm qee txoj kev, nws lub hom phiaj yog muab cov khoom nto zoo nkauj, tiv thaiv corrosion, txoj kev kho saum npoo: electroplating, kub dip galvanizing, mechanical plating, thiab lwm yam.
Founded hauv 1999, nws yog ib tug kws fastener manufacturing thiab muag khoom txwv tuam txhab. Tam sim no, muaj ob lub chaw tsim khoom loj hauv Tianjin thiab Ningbo, muaj peev xwm tsim tau 1,000 tons / hli.
Cov khoom tseem ceeb yog carbon steel, alloy steel bolts, ceev, stainless hlau bolts, ntsia hlau. Npog ntau yam qauv, ntawm cov ntsia hlau xws li hex self tapping ntsia hlau thiab Hex taub hau ntoo ntsia hlau nrog EPDM ntxhua khaub ncaws yog ib qho ntawm cov khoom sib tw tshaj plaws ntawm peb lub tuam txhab.
