Ngatirambei tichisuma maitiro ese eMetal Injection Molding tekinoroji.
Nhasi tichakurukura nezve sintering iyo inonyanya kukosha mapoinzi panguva yeMIM.
RUZIVO RWOKUTANGA ROKUPINDA
1) Sintering ndeyekupisa uye kunzwa hupfu hwakapetwa pane tembiricha yakadzikira pane inonyungudika yezvikamu zvayo zvikuru, wozoitonhodza neimwe nzira uye nekumhanya, nekudaro ichivandudza strenth uye zvakasiyana-siyana zvemuviri uye zvemagetsi zvimiro zve compact uye kuwana. imwe metallographic structure.
2) Iyo yakakosha maitiro ndeyePowder compact-Furnace Charging-Sintering inosanganisira Preheating, Kuchengetedza Kupisa uye Kutonhora-Kupisa-Sintered zvigadzirwa.
3) Basa rekuita sintering kutora mafuta ekubvisa, metallurgical bonding, element diffusion, dimensional shanduko, microstructure uye ocidation kudzivirira.
MASHOKO MUPFUPI YEMAITIRO YOKUTISA
1) Yakaderera tembiricha Pre-sintering nhanho:
Mune ino nhanho, kudzoreredzwa kwesimbi, volatilization ye adsorbed gasi uye unyoro, kuora uye kubviswa kweanoumba agent mune compact.
2) Yepakati tembiricha kupisa sintering nhanho:
Recrystallization inotanga panguva ino.Kutanga, iyo yakaremara yekristaro tsanga inodzoserwa mukati mezvimedu uye inorongwazve kuita nyowani yekristaro tsanga.Panguva imwecheteyo, ma oxides ari pamusoro pezvimedu zvakaderedzwa zvachose, uye iyo particle interface inoumba sintering mutsipa.
3) High termperture inonzwa kuchengetedza kuti upedze sintering nhanho:
Iyi nhanho ndiyo nzira huru yekunyura, senge kupararira uye kuyerera kwakazara kuenderera uye pedyo nekupedzwa, kuumba nhamba huru yeakavharika pores, uye kuramba ichidzikira, kuitira kuti saizi yepamberi uye nhamba yakazara yepores ideredzwe, uye density. yemuviri we sintered unowedzera zvakanyanya.
4) Kutonhora nhanho:
Iyo chaiyo sintering process inoramba ichiita sintering, saka maitiro kubva kune sintering tembiricha kuti inonoke kutonhora kwekanguva uyezve nekukurumidza kutonhora kusvika muchoto chinobuda chasvika mukamuri tembiricha zvakare nhanho iyo austenite inoora uye chimiro chekupedzisira chinoumbwa zvishoma nezvishoma.
Pane zvakawanda zvinopesvedzera zvinhu zvinokanganisa iyo sintering process.Uye zvinhu zvinosanganisira tembiricha, nguva, mhepo, kuumbwa kwezvinhu, alloy nzira, lubricant yemukati uye sintering process senge kupisa uye kutonhora chiyero.Zvinogona kuonekwa kuti imwe neimwe linke ine simba rakakosha pamhando ye sintering.Kune zvigadzirwa zvine zvimiro zvakasiyana uye hupfu hwakasiyana, maparameter akasiyana anoda kugadziridzwa.
