Metal haisi iyo chete zvinhu zvinogona kukandwa, plastiki inogonawo kukandwa.Zvinhu zvakapfava-pamusoro-soro zvinogadzirwa nekudururira zvinhu zvepurasitiki zvemvura muforoma, zvichiita kuti zvirape pakamuri kana tembiricha yakaderera, uyezve kubvisa chigadzirwa chakapedzwa.Iyi nzira inowanzonzi kukanda.Zvinowanzoshandiswa zvinhu acrylic, phenolic, polyester uye epoxy.Iwo anowanzo shandiswa kugadzira maburi zvigadzirwa, mapaneru, nezvimwewo, vachishandisa mapurasitiki maitiro anosanganisira dip molding, slurry molding, uye kutenderera kuumbwa.
(1) Donhedza kuumba
Iyo yakanyanya tembiricha mold yakanyikwa mumvura yakanyungudutswa yepurasitiki, yozotorwa zvishoma nezvishoma kunze, yakaomeswa, uye pakupedzisira chigadzirwa chakapedzwa chinopepetwa kubva mukuumbwa.Iyo yekumhanyisa iyo mold inobviswa kubva mupurasitiki inoda kudzorwa.Iyo inononoka kumhanya, iyo inokora yepurasitiki layer.Iyi nzira ine zvakanakira mutengo uye inogona kugadzirwa mudiki mabhechi.Inowanzo shandiswa kugadzira zvinhu zvisina mhango semabharumu, magurovhosi epurasitiki, zvibatiso zvemawoko nemidziyo yekurapa.
(2) Condensation molding
Iyo yakanyungudutswa yepurasitiki mvura inodirwa mumhando yepamusoro-yekushisa kugadzira chigadzirwa chisina mhango.Mushure mokunge plastiki ichiita mutsara pamusoro pemukati wemold, iyo yakawandisa inodururwa.Mushure mekunge plastiki yasimbiswa, mold inogona kuvhurwa kuti ibvise chikamu.Iyo yakareba plastiki inoramba iri muforoma, iyo gobvu inokora.Iyi idanho repamusoro rekusununguka iro rinogona kuburitsa mamwe maumbirwo akaomarara ane yakanaka cosmetic rondedzero.Zvemukati zvemota zvinowanzo gadzirwa zvePVC neTPU, izvo zvinowanzo shandiswa panzvimbo dzakaita semadhibhodhi uye zvibato zvegonhi.
3) Kutenderera kuumbwa
Imwe chiyero chepurasitiki yakanyunguduka inoiswa mumoto unopisa zvidimbu zviviri zvakavharwa, uye mold inotenderedzwa kugovera zvinhu zvakafanana pamadziro efodya.Mushure mekusimba, mold inogona kuvhurwa kuti ibvise chigadzirwa chakapedzwa.Munguva iyi, mhepo kana mvura inoshandiswa kutonhora chigadzirwa chakapedzwa.Chigadzirwa chakapedzwa chinofanira kunge chine mhango, uye nekuda kwekutenderera, chigadzirwa chakapedzwa chichava nekanyoro nyoro.Pakutanga, huwandu hwemvura yepurasitiki inosarudza madziro emadziro.Inowanzo shandiswa kugadzira axially symmetrical kutenderera zvinhu zvakaita sehari yemaruva ehari, zvekutamba zvevana, mwenje wemwenje, shongwe yemvura midziyo, nezvimwe.
