1. Nyob rau hauv tsos, qhov sib txawv ntawm seamless steel yeeb nkab thiab welded steel yeeb nkab yog hais tias muaj weld tuav nyob rau hauv lub puab phab ntsa ntawm cov yeeb nkab welded, thaum tsis muaj seamless steel yeeb nkab.
2. Lub siab ntawm cov yeeb nkab seamless siab dua, cov yeeb nkab welded feem ntau yog li 10 MPa, thiab tam sim no cov yeeb nkab welded tau ua tiav. Lub seamless steel yeeb nkab yog perforated nrog ib puag ncig cov yeeb nkab. Tsis muaj qhov sib txawv, welded yeeb nkab yog cov yeeb nkab steel uas ua los ntawm vuam steel phaj lossis steel sawb tom qab crimping thiab sib sau, thiab muaj ib qho zawj. Feem ntau, seamless kav yuav tiv taus siab dua.
3. Lub seamless steel yeeb nkab yog tsim nyob rau tib lub sijhawm thaum dov. Welded steel kav yuav tsum tau welded tom qab dov, feem ntau yog muab kauv vuam thiab ncaj welding. Piv nrog rau kev ua tau zoo, lub raj seamless zoo dua, thiab tau kawg tus nqi siab dua.

Q: Cov khoom siv twg muaj? Koj puas ua raws li daim ntawv pov thawj rohs?
A: dofo springs muaj peev xwm ua ntau hom springs, compression springs, kos springs, torsion springs, hlau, thiab ntau yam high-end caij nplooj ntoos hlav steel - Carbon Steel - Stainless hlau - suab paj nruag nyob ntawm tej, tag nrho cov raws li rohs qauv. Txoj kab uas hla ntawm txoj kab uas hla ntawm 0001 nti mus rau 0075 nti thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov ntawv thov sib txawv. Tag nrho cov ntaub ntawv caij nplooj ntoos hlav ua raws li European rohs ntawv pov thawj.
Q: Koj puas txhawb nqa cov xaj me me lossis tsuas yog lees txais cov xaj loj?
A: Dover Spring ua rau muaj coob tus springs thiab ib tug me me ntawm springs raws li koj xav tau. Peb yuav ua haujlwm nrog koj los xaiv cov kev daws teeb meem zoo tshaj plaws.
Q: Puas yog dofo springs muab lub caij nplooj ntoos hlav tsim lossis kev pabcuam thawj zaug?
A: Peb cov engineers tuaj yeem pab tsim cov duab kos thiab qhia kom txo cov nqi tsim khoom. Peb cov engineers muaj ntau xyoo ntawm kev paub nyob rau hauv lub caij nplooj ntoos hlav tsim. Peb tuaj yeem muab kev kos duab thiab qauv qauv rau cad, 3D thiab 2d layout designs.
Q: Dab tsi yog lub sij hawm xa tuaj rau kev cai springs?
A: Kev xa khoom mus rau kev cai springs txawv. Rau compression springs, kos springs, torsion springs, thiab xaim nyob rau hauv peb cov pwm series, peb tuaj yeem xa hauv 25 hnub. Txawm li cas los xij, rau qee qhov kev sib tw zoo nkauj, lub sijhawm xa khoom yog li 30-40 hnub.
Q: Koj puas them rau cov qauv caij nplooj ntoos hlav kev cai?
A: Peb underwrite kev cai caij nplooj ntoos hlav qauv raws li kev txiav txim. Hauv lwm lo lus, thaum peb tau txais qhov kev txiav txim, tus nqi coj mus kuaj tuaj yeem rov qab tau. Txawm li cas los xij, yog tias koj tus qauv xav tau pwm ntxiv, peb yuav them nqi.
Q: Yog tias peb txiav txim siab ntau lub caij nplooj ntoos hlav, koj puas yuav tso cov kab thiab cov kab hauv tsev rau peb, ces xa tuaj rau peb raws li xav tau?
A: Peb lub tsev khaws khoom muaj cov kev pabcuam tshwj xeeb rau kev lag luam mus ntev. Koj tuaj yeem ua ib qho kev npaj thauj khoom txhua xyoo thiab txhua hli. Peb yuav nkoj raws li lub sijhawm tshwj xeeb.
Q: Txoj kev them nyiaj dab tsi peb lees txais rau lub caij nplooj ntoos hlav xaj?
A: Peb tuaj yeem lees txais txoj kev them nyiaj raws li T / t, pom cov ntawv credit, dp, westunion
Cim npe nrov: tawv seamless raj, tus neeg muag khoom, customized, lag luam wholesale, pheej yig, luv nqi, daim ntawv teev npe, tus nqi qis, hauv Tshuag, dawb qauv
