Tuag casting yog cov txheej txheem tsim tau zoo heev uas tuaj yeem tsim cov khoom nrog cov duab nyuaj. Nrog kev tuag casting, cov dab dej kub tuaj yeem muab tso rau hauv ib lub thav duab, vaj tse lossis cov ntaub thaiv npog, yog li cov cua sov tuaj yeem xa ncaj qha los ntawm qhov chaw mus rau ib puag ncig yam tsis muaj kev tiv thaiv ntxiv. Thaum siv rau nws lub peev xwm tag nrho, tuag casting tsis yog tsuas yog kev ua haujlwm zoo thermal, tab sis kuj tseem ceeb txuag nqi.
Cov txiaj ntsig ntawm Die Cast Heat Sinks
Piv nrog rau lwm txoj kev tsim khoom, tuag casting muaj cov txiaj ntsig hauv qab no:
● Tsim cov duab 3D nyuaj uas tsis tuaj yeem ua rau extrusion lossis forging
● Cov dab dej kub, thav duab, vaj tse, cov ntaub thaiv npog thiab cov hlua khi tuaj yeem ua ke rau hauv ib qho kev sib tsoo
●Qhov tuaj yeem raug cored hauv tuag casting
● Tus nqi ntau lawm thiab tus nqi qis
● Tight tolerances
● Dimensionally ruaj khov
● Secondary machining tsis tas yuav tsum tau
● Muab qhov chaw tiaj tus tshwj xeeb (zoo rau kev sib cuag ntawm lub dab dej kub thiab qhov chaw)
● Corrosion kuj tus nqi ntawm zoo mus rau siab
● Zoo heev EMI tiv thaiv RFI
Tuag cam khwb cia kub dab dej yuav ua tau nyob rau hauv zinc los yog txhuas. Zinc yog qhov yooj yim tshaj plaws kom tuag cam khwb cia. Nws cov cuab yeej thiab cov nqi tsev yog qis dua li cov khoom siv txhuas. Zinc tseem muaj zog, tawv thiab tawv dua li txhuas. Tuag cam khwb cia zinc kub dab dej tsis tas yuav plating, los yog plating yuav ua tau yooj yim. Zinc hnyav dua aluminium tab sis muab kev xav zoo. Ntawm qhov tod tes, aluminium yog sib dua thiab qee cov aluminium alloys muaj thermal conductivity ntau dua li zinc alloys.
