Nrog ntau tshaj 10 xyoo kev paub nyob rau hauv kev cai precision machining cov kev pab cuam, peb tau cog lus los muab cov khoom zoo nrog cov nqi sib tw.
Peb tuaj yeem muab CNC precision machining qhov chaw, CNC tig qhov chaw, CNC milling qhov chaw, nto sib tsoo, CNC engraving thiab lwm yam.
Cov khoom tuaj yeem tsim los ntawm 1mm txog 300mm hauv txhuas, hlau alloy, stainless hlau, tooj dag thiab yas (nylon, PMMA, teflon thiab lwm yam).
Thiab peb tseem tuaj yeem ua cov txheej txheem thib ob thiab kev sib dhos ua haujlwm rau koj thaum CNC prototyping lossis ntau lawm tiav.
Ntau tshaj 10 xyoo kev paub ntawm kev tsim thiab tsim txhua yam ntawm precision machining qhov chaw.
CNC Precision Machining Hlau qhov chaw rau cov neeg muas zaub txawv teb chaws thiab domestically.
Tshwj xeeb hauv kev tsim cov khoom lag luam thiab cov khoom siv nrog nruj tolerances thiab cov duab nyuaj.
OEM Ductile hlau xuab zeb castings, poob ua npuas ncauj casting, Nqus Moulding thiab lwm yam, cov khoom siv tes ua molding yuav raug txiav raws li qhov kev thov siab ntev thiab kev thov kom muaj nuj nqis.Feem ntau ntawm peb cov castings yog siv rau li qub, hydrants, twj, tsheb, tsheb ciav hlau thiab tsheb ciav hlau thiab lwm yam.
Cam khwb cia hlau yog ib qho alloy uas muaj hlau, carbon, thiab silicon.
Nyob rau hauv cov alloys, cov ntsiab lus ntawm cov pa roj carbon ntau tshaj cov nyiaj uas yuav khaws cia rau hauv austenite khoom tov ntawm eutectic kub.
cam khwb cia hlau yog cov hlau-carbon alloy nrog cov ntsiab lus carbon ntau dua 2.11% (feem ntau 2.5 ~ 4%). thiab lwm yam impurities tshaj carbon steel.Qee lub sij hawm nyob rau hauv thiaj li yuav txhim kho lub mechanical zog ntawm cam khwb cia hlau los yog lub cev, tshuaj lom neeg zog, tab sis kuj ntxiv ib tug tej yam nyiaj ntawm alloy ntsiab, alloy cam khwb cia hlau.
Raws li thaum ntxov xyoo pua BC hnub nyoog, Tuam Tshoj tau pib siv cam khwb cia hlau, dua li European lub teb chaws ze li ob txhiab xyoo dhau los.Cast hlau tseem yog ib qho ntawm cov khoom tseem ceeb tshaj plaws hauv kev tsim khoom.
ib qho raws li daim ntawv ntawm cov pa roj carbon tam sim no nyob rau hauv cam khwb cia hlau, cam khwb cia hlau yuav muab faib ua
1.White cam khwb cia hlau tshwj tsis yog rau ob peb soluble nyob rau hauv ferrite, cov seem ntawm cov carbon nyob rau hauv daim ntawv ntawm cementite muaj nyob rau hauv cam khwb cia hlau, nws puas yog silver-dawb, thiaj li hu ua dawb cam khwb cia hlau.White cam khwb cia hlau yog tsuas yog siv raws li raw khoom. rau steelmaking thiab dawb paug rau ua malleable cam khwb cia hlau.
2.Grey cam khwb cia hlau carbon tag nrho los yog feem ntau ntawm cov flake graphite muaj nyob rau hauv cov cam khwb cia hlau, nws tawg yog tsaus grey, thiaj li hu ua grey cam khwb cia hlau.
3.Ib feem ntawm cov pa roj carbon ntawm hemp cam khwb cia hlau muaj nyob rau hauv daim ntawv ntawm graphite, uas zoo ib yam li grey cam khwb cia hlau.Lwm ib feem yog nyob rau hauv daim ntawv ntawm dawb cementite zoo ib yam li dawb cam khwb cia hlau.Cov dub thiab dawb pitting nyob rau hauv lub puas, thiaj li hu ua hemp cam khwb cia hlau.Qhov no hom cam khwb cia hlau kuj muaj ntau dua hardness thiab brittleness, yog li nws tsis tshua muaj siv nyob rau hauv kev lag luam.
Ob Raws li qhov sib txawv graphite morphology hauv cam khwb cia hlau, cam khwb cia hlau tuaj yeem muab faib ua
1.Lub graphite hauv grey cam khwb cia hlau yog flake.
2.Lub graphite nyob rau hauv malleable cam khwb cia hlau yog flocculent.Nws yog tau los ntawm tej yam dawb cam khwb cia hlau tom qab annealing ntawm siab kub rau ib ntev lub sij hawm.Nws cov khoom (tshwj xeeb yog toughness thiab plasticity) yog siab tshaj grey cam khwb cia hlau, yog li nws yog feem ntau hu ua malleable cam khwb cia hlau.
3.The graphite nyob rau hauv nodular cam khwb cia hlau yog spherical.Nws yog tau los ntawm spheroidizing kev kho mob ua ntej pouring molten hlau.Qhov no hom ntawm cam khwb cia hlau tsis tsuas yog muaj siab mechanical zog tshaj grey cam khwb cia hlau thiab malleable cam khwb cia hlau, tab sis kuj muaj ib tug yooj yim ntau lawm txheej txheem dua. malleable cam khwb cia hlau.Ntxiv mus, nws cov khoom siv kho tshuab tuaj yeem txhim kho ntxiv los ntawm kev kho cua sov, yog li nws tau siv dav hauv ntau lawm.
tuam txhab kev taw qhia:
Hebei Mingda International Trading Company yog lub tuam txhab ua lag luam uas tshwj xeeb hauv kev castings, forgings thiab machinery qhov chaw.
Peb cov khoom muaj xws li txhua yam ntawm raw castings yuav ua los ntawm ductile hlau, grey hlau, tooj dag, stainlesssteel thiab txhuas,
machined castings thiab forged qhov chaw.Txhawm rau ua cov khoom no raws li cov neeg siv khoom kos duab,
peb muaj cov khoom tsim nyog tsim khoom siv tes ua thiab cov khoom siv, xws li cob xuab zeb, xuab zeb pwm, kub tub ntxhais thawv, ploj-wax, poob ua npuas ncauj thiab lwm yam.
Tshwj xeeb tshaj yog rau lub cev hydrant thiab li qub 'lub cev, peb tau sau cov kev paub nplua nuj rau cov khoom no yav dhau los 16 xyoo kev tsim khoom,
Tam sim no peb txaus siab rau peb cov khoom nrog zoo nto thiab high quality khoom.Txawm li cas los xij, peb tau sim peb qhov zoo tshaj plaws los muab peb cov neeg siv khoom zoo dua
castings los ntawm kev txhim kho cov khoom siv tes ua khoom siv thiab kev tswj xyuas zoo dua.
Nrhiav rau pem hauv ntej kom tau txais koj cov lus teb zoo tshaj plaws ntawm koj qhov ntxov tshaj plaws!
