Ib qho OEM kev cai tooj dag peev catings muab los ntawm Tuam Tshoj nrogCNC machining, kev kho deg thiab kev kho cua sov.
Peb tuaj yeem muab 3.1 Cov Ntawv Pov Thawj ntawm cov hlau casting raws li EN 10204 yog tias koj xav tau. Muaj cov kev tshuaj ntsuam xyuas: qhov ntsuas qhov loj me los ntawm CMM, kev ntsuas tsis muaj kev puas tsuaj, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, ntsuas qhov nyuaj, ntsuas qhov ntsuas zoo li qub, ntsuas qhov ntsuas, ntsuas huab cua thiab dej siab.
Raws li cov ntaub ntawv sib txawv siv los ua lub plhaub, cov peev txheej tuaj yeem muab faib ua silica sol casting thiab dej iav casting. silica sol peev txheej txheej txheem casting muaj qhov zoo dua Dimensional Casting Tolerances (DCT) thiab Geometrical Casting Tolerances (GCT) dua li cov txheej txheem iav dej. Txawm li cas los xij, txawm tias los ntawm tib txheej txheem casting, Qib Siab Siab yuav txawv ntawm txhua qhov cam khwb cia hlau vim lawv ntau yam castability. Peb lub tuam txhab xav tham nrog koj yog tias koj muaj kev thov tshwj xeeb ntawm qhov yuav tsum tau ua. Ntawm no yog cov hauv qab no yog cov qib tolerances uas peb tuaj yeem ncav cuag ob qho tib si los ntawm silica sol casting thiab dej iav casting txheej txheem cais:
✔ DCT Qib los ntawm Silica Sol Lost Wax Casting: DCTG4 ~ DCTG6
✔ DCT Qib los ntawm Dej iav Poob Wax Casting: DCTG5 ~ DCTG9
✔ GCT Qib los ntawm Silica Solt Wax Casting: GCTG3 ~ GCTG5
✔ GCT Qib los ntawm Dej iav Poob Wax Casting: GCTG3 ~ GCTG5
Raws li cov tooj liab-raws li alloys, tooj dag thiab bronze tuaj yeem tsim rau hauv qhov nyuaj heev, ua rau lawv zoo tagnrho rau covpeev casting txheej txheem. Kev hloov pauv tus nqi tas li tuaj yeem ua rau cov ntaub ntawv no tus nqi siab heev, ua rau cov khoom pov tseg kim heev, tshwj xeeb tshaj yog thaum txiav txim siab CNC machining thiab / lossis forging raws li cov txheej txheem tsim khoom los tsim koj qhov chaw casting. Ntshiab tooj liab tsis yog feem ntau cam khwb cia. Kev nqis peev (poob ciab) casting yog ib txoj hauv kev ntawm precision casting complex ze-net-puab cov ntsiab lus siv cov qauv ntawm cov qauv siv quav ciab. Kev nqis peev casting lossis poob ciab yog cov txheej txheem hlau uas feem ntau siv cov qauv siv quav ciab ncig los ntawm lub plhaub ceramic los ua cov pwm ceramic. Thaum lub plhaub dries, siv quav ciab yog melted tam sim ntawd, tawm tsuas yog cov pwm. Tom qab ntawd cov khoom siv casting yog tsim los ntawm cov hlau molten rau hauv cov pwm ceramic.
Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Brass uas muaj tooj liab thiab zinc yog hu ua tooj dag zoo tib yam. Yog tias nws yog ntau hom alloys uas muaj ntau tshaj li ob lub ntsiab lus, nws yog hu ua tooj dag tshwj xeeb. Brass yog tooj liab alloy nrog zinc ua lub ntsiab tseem ceeb. Raws li zinc cov ntsiab lus nce, lub zog thiab plasticity ntawm cov alloy nce ntau, tab sis cov khoom siv kho tshuab yuav txo qis tom qab ntau tshaj 47%, yog li zinc cov ntsiab lus ntawm tooj dag yog tsawg dua 47%. Ntxiv nrog rau zinc, cam khwb cia tooj dag feem ntau muaj cov alloying xws li silicon, manganese, txhuas, thiab txhuas.
Casting tooj dag muaj cov khoom siv ntau dua li tooj liab, tab sis tus nqi qis dua bronze. Cam khwb cia tooj dag feem ntau yog siv rau lub hom phiaj dav dav bearing bushings, gears thiab lwm yam hnav-resistant qhov chaw thiab li qub thiab lwm yam corrosion-resistant qhov chaw. Brass muaj zog hnav tsis kam. Brass feem ntau yog siv los ua cov li qub, cov kav dej, txuas cov kav dej rau cov cua txias sab hauv thiab sab nraud, thiab cov radiators.
