Tsika yendarira vharafu zvikamu mupi nekudyara kate kubva kuChina neCNC machining, kurapwa kwepamusoro uye masevhisi ekurapa kupisa.
Sezvo iyo mhangura-yakavakirwa alloys, ndarira nendarira zvinogona kuumbwa kuita zvikamu zvakaoma kwazvo, zvichiita kuti zvive zvakanakirainvestment casting process. Kuchinja-chinja kwemitengo nguva dzose kunogona kuita kuti zvinhu izvi zvive zvakanyanya kukoshesa mutengo, zvichiita kuti tsvina idhure zvakanyanya, kunyanya kana uchifunga CNC machining uye / kana kuforoma senzira yekugadzira kugadzira yako yekukanda zvikamu. Mhangura yakachena haiwanzokandwa. Investment (yakarasika wakisi) inzira yekukandira nemazvo padhuze-neti-shape details uchishandisa kudzokororwa kwewakisi. Investment casting kana kurasika wakisi isimbi yekugadzira nzira iyo inowanzo shandisa wakisi pateni yakakomberedzwa negoko receramic kugadzira mold yeceramic. Kana goko raoma, wakisi inonyunguduka, kuchisiya mold chete. Zvadaro chikamu chekukanda chinoumbwa nekudururira simbi yakanyungudutswa mumucheka weceramic.
Brass isimbi yemhangura ine zingi sechinhu chikuru. Sezvo zinc yemukati inowedzera, simba uye plastiki yealloy inowedzera zvakanyanya, asi michina yemagetsi inoderera zvakanyanya mushure mekupfuura 47%, saka iyo zinc yendarira iri pasi pe47%. Kuwedzera kune zinc, ndarira yakakandwa kazhinji ine alloying zvinhu zvakaita sesilicon, manganese, aluminium, uye lead.
Brass yekukanda ine yakakwirira mechanical properties pane bronze, asi mutengo wakaderera pane bhuronzi. Cast brass inowanzo shandiswa kune chinangwa chakajairwa kutakura makwenzi, mabhuranzi, magiya uye zvimwe zvisingapfekeri zvikamu uye mavharuvhu uye zvimwe zvikamu zvinodzivirira kuora. Brass ine simba rekuramba kupfeka. Brass inowanzoshandiswa kugadzira mavharuvhu, pombi dzemvura, mapombi ekubatanidza emukati nekunze emhepo inofefetera, uye maraya.
Nzira dzekuongorora dziripo: chiyero chekuyedzwa neCMM, kusingaparadze kuyedza, makemikari kuumbwa, michina zvivakwa, kuomarara kuyedzwa, static kuenzanisa, kuenzanisa kwesimba, kudzvanywa kwemhepo uye kumanikidza kwemvura.
Zvinoenderana neakasiyana binder zvinhu zvinoshandiswa kugadzira goko, iyo yekukanda mari inogona kupatsanurwa kuita silica sol casting uye yekukanda girazi remvura. Iyo silica sol investimendi yekukandira maitiro ine zvirinani Dimensional Casting Tolerances (DCT) uye Geometrical Casting Tolerances (GCT) pane girazi remvura maitiro. Nekudaro, kunyangwe nenzira imwechete yekukanda, iyo Tolerance Giredhi ichave yakasiyana kubva kune yega yega alloy nekuda kwekukandira kwavo kwakasiyana. Yedu yekutanga inoda kutaura newe kana uine chikumbiro chakakosha pane zvinodiwa kushivirira. Pano mune zvinotevera giredhi rekushivirira giredhi isu tinogona kusvika kune zvese ne silica sol casting uye yemvura girazi yekukanda maitiro zvakasiyana:
- ✔ DCT Giredhi naSilica Sol Yakarasika Wax Kukanda: DCTG4 ~ DCTG6
- ✔ DCT Giredhi neMvura Girazi Yakarasika Wax Kukanda: DCTG5 ~ DCTG9
- ✔ GCT Giredhi naSilica Sol Yakarasika Wax Kukanda: GCTG3 ~ GCTG5
- ✔ GCT Giredhi neMvura Girazi Yakarasika Wax Kukanda: GCTG3 ~ GCTG5
