Fastener Kev Lag Luam Txheej Txheem
Txhais
Fasteners yog ib lo lus dav dav rau ib hom kev siv tshuab siv los txuas ob lossis ntau qhov chaw (los yog cov khoom siv) ua ke los ua ib qho tag nrho. Lawv yog cov cuab yeej siv tshuab yooj yim tshaj plaws, dav siv hauv tsheb, lub zog, hluav taws xob, khoom siv hluav taws xob, tshuab, thiab lwm yam lag luam. Ntau yam fasteners tuaj yeem pom nyob rau hauv ntau yam khoom siv tshuab, tsheb, nkoj, railways, txuas hniav, tsev, ntsuas ntsuas, thiab lwm yam.
Raws li cov khoom lag luam kev faib tawm, fasteners feem ntau suav nrog 12 pawg hauv qab no: bolts, studs, screws, ceev, tus kheej tapping screws, ntoo screws, washers, tuav rings, pins, rivets, vuam rau tes, sib dhos, thiab kev sib txuas ua ke. Qhov no kuj yog txoj kev cais ib txwm siv rau cov fasteners hauv kuv lub teb chaws, thiab cov txheej txheem kev faib tawm no tau siv rau hauv kuv lub teb chaws cov qauv. Ntawm lawv, raws li seb cov qauv geometric muaj cov yam ntxwv ntawm threaded, fasteners tau muab faib ua threaded fasteners (xws li bolts, txiv ntseej, thiab lwm yam) thiab non-threaded fasteners (xws li washers, tuav rings, pins, zoo tib yam rivets, nplhaib zawj rivets. , thiab lwm yam).
Kev lag luam saw kev tsom xam: thaj chaw hauv qab daim ntawv thov yog dav dav
Cov dej ntws ntawm kev lag luam fastener feem ntau suav nrog cov khoom siv raw thiab cov khoom siv fastener, cov khoom siv raw muaj xws li steel, non-ferrous hlau xws li tooj liab thiab txhuas, thiab yas; fastener ntau lawm cov cuab yeej suav nrog cov tshuab taub hau txias, kub forging tshuab, thiab lwm yam.
Lub midstream ntawm lub fastener kev lag luam yog cov khoom txuas ntawm fasteners, uas yuav muab faib ua hlau fastener ntau lawm thiab yas fastener ntau lawm raws li cov ntaub ntawv fastener.
Daim ntawv thov hauv qab no yog dav, suav nrog tsheb, tshuab, khoom siv hauv tsev, kev tsim kho, kev tsheb ciav hlau, kev tsim nkoj, thiab lwm yam.
Kev lag luam keeb kwm kev loj hlob: lub suab thoob ntiaj teb tseem nce ntxiv
Upstream mov: Tuam Tshoj nyob rau hauv lub ntiaj teb no nyob rau hauv steel ntau lawm, thiab zus tau tej cov tooj liab, txhuas, thiab lwm yam hlau tseem nce.
Lub ntsiab raw khoom ntawm cov khoom fastener yog steel. Raws li cov ntaub ntawv los ntawm National Bureau of Statistics, kuv lub teb chaws cov hlau tsim tau pom qhov hloov pauv thiab nce zuj zus los ntawm 2015 txog 2021. Hauv 2021, kuv lub teb chaws cov hlau tsim tau mus txog 1336.668 lab tons, nce mus txog qhov siab tshaj plaws hauv xyoo tas los no. , nce ntawm 0.6% xyoo-rau-xyoo, thiab qhov kev loj hlob tau poob qis heev. Nyob rau hauv 2022, cov zis tau mus txog 1.34 billion tons, thiab nyob rau hauv 2023, steel ntau lawm mus txog 1362.68 lab tons, nce 5.2% xyoo-rau-xyoo.
Ntxiv rau cov hlau, tooj liab, thiab txhuas kuj tseem yog cov ntaub ntawv tseem ceeb rau cov khoom siv fastener. Piv nrog rau steel fasteners, tooj liab fasteners muaj qhov zoo ntawm kev ua tau zoo dua, thaum aluminium fasteners yog sib dua thiab muaj zog dua qhov sib piv.
Txij li thaum 2016, kuv lub teb chaws cov tooj liab refined thiab thawj aluminium ntau lawm feem ntau qhia ib tug upward trend. Hauv xyoo 2022, kev tsim cov tooj liab ua kom zoo tau mus txog 11.1153 lab tons, nce 5.99% xyoo-rau-xyoo, thaum thawj cov khoom siv txhuas tau mus txog 40.1443 lab tons, nce 4.26% xyoo-rau-xyoo. Nyob rau hauv 2023, Tuam Tshoj tus refined tooj liab thiab thawj aluminium ntau lawm yuav ncav cuag 12.99 lab tons thiab 41.59 lab tons, feem.
Kev lag luam kev txhim kho mob cov ntsiab lus: tsis muaj zog core technology thiab cov khoom tsim tsis tsim nyog
Cov thev naus laus zis tseem ceeb ntawm kuv lub teb chaws txoj kev lag luam fastener yog qhov tsis muaj zog, feem ntau tshwm sim hauv cov tub ntxhais kawm tsis muaj peev xwm thev naus laus zis tshiab, ob peb yam khoom siv thev naus laus zis, ntev R & D cycles, thiab kev ua haujlwm qis. Kev lag luam fastener raug pib lig hauv kuv lub teb chaws. Txawm hais tias cov tuam txhab lag luam hauv tsev tau ua tiav cov txiaj ntsig tseem ceeb hauv kev zom thiab nqus cov thev naus laus zis txawv teb chaws, tag nrho, tseem muaj qhov sib txawv loj ntawm kev ywj pheej tshiab thiab thev naus laus zis R & D muaj peev xwm ntawm cov lag luam hauv tsev thiab cov lag luam txawv teb chaws. Tsis tas li ntawd, kev tsim tshuab ntawm high-end fasteners nws tus kheej suav nrog ntau qhov chaw, kev nyuaj siab, thiab tsis muaj cov kws tshaj lij R & D thiab cov neeg ua haujlwm tshiab, uas ua rau kuv lub teb chaws cov txuj ci, thev naus laus zis, thiab cov cuab yeej siv nyob rau hauv rau rau qhov kev lag luam loj ntawm cov ntaub ntawv science. , kev tshawb fawb siab, cov kws tshaj lij, kev kho deg, kev kho cua sov, thiab kev sim kev tshawb fawb xav tau rau kev tsim cov high-end fasteners muaj qee qhov sib txawv nrog txawv teb chaws.
Tsis tas li ntawd, cov txheej txheem irrationality tsim los ntawm lub sij hawm mus sij hawm tsawg-theem duplicate tsim tau coj mus rau ib tug structural seem nyob rau hauv kuv lub teb chaws fastener ntau lawm. Ntawm qhov tod tes, kev ua lag luam rau cov fasteners zoo tib yam yog saturated, cov khoom yog overstocked, thiab ntau lawm muaj peev xwm yog oversupplied, uas ua rau qis-theem duplicate tsim thiab homogeneous vicious kev sib tw. Ntawm qhov tod tes, cov cuab yeej siv zog siab siv hauv kev lag luam xws li tsheb, infrastructure, aerospace, thiab engineering machinery yog luv luv. Feem ntau cov tuam txhab lag luam hauv tsev muaj peev xwm R & D tsis muaj zog thiab cov cuab yeej ua haujlwm tsawg. Tsuas yog ob peb lub tuam txhab hauv tebchaws tau koom nrog kev lag luam high-end kev lag luam thiab yuav tsum tau cia siab rau kev xa khoom mus ntev.
Kev lag luam kev loj hlob zeem muag
Cov kev taw qhia ntawm cov khoom tsim kho nyob rau hauv Tuam Tshoj lub fastener kev lag luam yog ua kom paub meej. High-end fastener cov khoom lag luam hauv kev lag luam yuav loj hlob sai, thiab cov khoom lag luam ntxiv tus nqi yuav nce sai. Nyob rau tib lub sijhawm, txoj kev loj hlob ntawm kev lag luam txawv teb chaws xws li cov teb chaws raws Txoj Kev Siv thiab Txoj Kev yuav txhawb nqa kev loj hlob ntawm kev lag luam xa tawm hauv kuv lub teb chaws kev lag luam fastener. Nws cia siab tias kev lag luam loj ntawm kuv lub teb chaws kev lag luam fastener yuav loj hlob ntxiv nyob rau hauv tsib xyoos tom ntej. Los ntawm 2028, kev lag luam loj ntawm Tuam Tshoj txoj kev lag luam fastener yuav tshaj 180 billion yuan.
