Kev lag luam fastener ua lub luag haujlwm tseem ceeb hauv kev tsim khoom thiab kev tsim kho, muab cov khoom tseem ceeb uas tuav txhua yam ua ke. Cov fasteners muaj ntau hom xws li bolts, txiv ntoo, self-tapping screws, wood screws, plugs, rings, washers, pins, rivets, assemblies, joints, weld studs, thiab lwm yam. Cov khoom siv kho tshuab no yog ua los ntawm cov hlau tsis yog ferrous xws li hlau, tooj liab thiab txhuas, nrog rau cov yas. Kev tsim cov fasteners siv cov khoom siv precision, xws li cov tshuab txias thiab cov tshuab kub forging, kom ntseeg tau tias lawv muaj kev ruaj khov thiab lub zog.
Ib qho ntawm cov zog tseem ceeb ntawm kev lag luam fastener yog kev loj hlob ntawm ntau yam kev lag luam xws li metallurgy, tshuab, hluav taws xob, tsheb thiab kev tsim kho hauv Suav teb. Raws li cov kev lag luam no txuas ntxiv nthuav dav, qhov kev thov rau fasteners kuj nce ntxiv. Xyoo 2018, kuv lub teb chaws cov khoom fastener tau txog 8.02 lab tons, thiab nws xav tias yuav nce mus txog 9.29 lab tons los ntawm xyoo 2022.
Kev lag luam tsheb yog ib qho ntawm cov ntawv thov tseem ceeb tshaj plaws rau cov khoom siv txuas. Kev thov rau cov khoom siv tsheb, suav nrog kev lag luam txuas, txuas ntxiv loj hlob thaum Tuam Tshoj dhau los ua tus tsim khoom thiab cov neeg siv khoom loj tshaj plaws. Raws li cov ntaub ntawv tsis ntev los no, kev tsim khoom thiab kev muag khoom ntawm cov tsheb thauj neeg hauv kuv lub tebchaws yuav ncav cuag 23.836 lab thiab 23.563 lab hauv xyoo 2022, nce ntxiv txhua xyoo ntawm 11.2% thiab 9.5%.
Cov ntsia hlau thiab cov ntsia hlauyog ob qho ntawm cov khoom siv txuas uas siv dav tshaj plaws. Cov ntsia hlau yog cov khoom siv txuas yooj yim, feem ntau yog ua los ntawm hlau, nrog lub taub hau ntse thiab lub taub hau tiaj tus, dav. Lawv raug ntaus rau hauv ntoo lossis lwm yam khoom siv los tuav lawv rau hauv qhov chaw. Cov ntsia hlau muaj ntau yam thiab muaj ntau qhov ntau thiab tsawg xws li cov ntsia hlau ib txwm muaj, cov ntsia hlau rau ru tsev, thiab cov ntsia hlau tiav.
Cov ntsia hlau yog cov khoom siv sib txuas uas nyuaj dua uas muaj ib lub shank uas muaj xov, ib lub qhov, thiab lub taub hau tiaj lossis lub taub hau slotted lossis lub taub hau Phillips rau kev tig nrog lub screwdriver lossis lub laum. Cov ntsia hlau yog siv los tuav cov khoom ua ke, muaj zog dua li cov ntsia hlau thiab zoo tagnrho rau kev siv tseem ceeb. Ntau hom ntsia hlau suav nrog cov ntsia hlau ntoo, cov ntsia hlau tshuab, cov ntsia hlau tus kheej, thiab cov ntsia hlau hlau.
Kev xaiv tus ntsia hlau kom raug rau ib txoj haujlwm tshwj xeeb yog qhov tseem ceeb heev. Cov ntsia hlau thiab cov ntsia hlau muaj ntau yam zoo nyob ntawm seb siv li cas. Cov ntsia hlau yog rau cov kev siv uas tsis tseem ceeb, xws li dai duab, thaum cov ntsia hlau yog rau cov kev siv uas xav tau lub zog thiab kev ruaj khov, xws li phab ntsa uas muaj thav duab. Thaum tuav ntoo ua ke, nws yog qhov zoo tshaj plaws los siv cov ntsia hlau vim lawv tuav tau ruaj khov dua thiab yuav tsis xoob dhau sijhawm.
Hauv kev xaus lus, cov ntsia hlau thiab cov ntsia hlau yog ob qho tseem ceeb ntawm kev lag luam fastener, muab kev sib txuas tsim nyog rau ntau yam kev siv. Raws li kev lag luam tsim khoom thiab kev tsim kho txuas ntxiv mus, qhov kev thov rau fasteners kuj tseem loj hlob tuaj. Kev xaiv cov cuab yeej zoo rau ib txoj haujlwm tshwj xeeb yuav tsum nkag siab txog nws cov yam ntxwv tshwj xeeb thiab cov kev xav tau ntawm kev siv.
