Ceramic yave chinhu chesarudzo chehungwaru kupfeka nekuda kwekukwenya-uchapupu, ganda-hushamwari, kwete-allergic, jade ruvara uye yakaderera mutengo. Uye ceramic jekiseni kuumba ndeimwe yeakanyanya kuumba maitiro ehungwaru inopfekeka yeceramic inoratidzika zvikamu.
Ceramic injection molding process
Ceramic jekiseni kuumbainzira yepedyo net size plastic molding nzira yakagadziridzwa pahwaro hwepolymer jekiseni rekugadzira tekinoroji. Iyo yakakosha maitiro ehungwaru inopfekwa yeceramic jekiseni kuumba inonyanya kusanganisira nhanho ina: kugadzirira kwekudya, jekiseni kuumba, degreasing uye sintering.
1. Kugadzirira kwekudya Iyo yttrium yakagadzikana zirconia powder uye surfactant inoyerwa muchiyero, ethanol inowedzerwa, yozosanganiswa nebhora rekugaya, yakaomeswa uye yakaongororwa kuti iwane slurry, uye zvino inosanganiswa nebinder, yakasanganiswa uye granulated kuti iwane chikafu chejekiseni.
Kiyi yekugadzira chikafu:
Sarudza yakakodzera binder, binder uye ceramic poda kuenderana uye shear dispersion yakanaka, bvisa agglomeration;
Yakakodzera binder yemukati, kuitira kuti chikafu chive nekuyerera kwakanaka;
Yakawedzera ceramic poda kurodha (yakasimba zvemukati) uye yakaderedzwa dimensional deformation.
2, kuumbwa kwejekiseni kuchava jekiseni rekuumba chikafu chinoiswa mumushini wekuumba jekiseni, inopisa muine viscous kunyunguduka, pane imwe tembiricha uye kudzvanywa jekiseni rekumhanya-mhanya musimbi mold, kutonhora mushure mekubvisa kuti uwane ceramic billet muviri. Kiyi yekugadzira jekiseni:
Inonzwisisika mold dhizaini uye kugadzirisa (gedhi, mumhanyi, kunyatsojeka, zvinhu, nezvimwewo)
Kugadzika uye optimization yejekiseni paramita (tembiricha, kumanikidza, tembiricha yekuumbwa)
Kupera uye kushushikana kwemuviri panguva yekuzadza mold
3, degreasing degreasing ndiyo maitiro ekubvisa binder chikamu mujekiseni molding ceramic billet nenzira dzemuviri kana kemikari. Nekuda kweiyo yakasiyana binder system, degreasing process yakasiyana, jekiseni rekuumba ceramic degreasing nzira dzinosanganisira: thermal degreasing, solvent degreasing, catalytic degreasing, sarudza inoshanda uye yakachengeteka degreasing tekinoroji yekubvisa, kuwana isina chinhu.
4. Sintering
Iyo ceramic isina chinhu yakanyungudutswa pakupisa kwepamusoro kwe1300 ° C ~ 1800 ° C. Sintering inzira yekugadzira ceramic billet. Chikamu chikuru chekushanda kwezvigadzirwa zveceramic zvinotsanangurwa nekupisa. Zirconia ceramics inoda kukwirira kwepamusoro uye yunifomu sintering, kwete chete iyo degreasing process yakakosha, asi zvakare inobatwa nehupfu, additives, sintering tembiricha uye nguva, kumanikidza uye sintering mamiriro uye zvimwe zvinhu.
Zvakanakira zveceramic jekiseni molding
Akangwara anopfekeka cheramic chitarisiko zvikamu zvinosanganisira ceramic wachi, keramic bezel, ceramic dial, ceramic pasi chivharo, ceramic korona, ceramic wachi cheni uye zvimwe zvigadzirwa, diki saizi, yakakwirira chaiyo zvinodiwa.
Zvakanakira kushandisa ceramic jekiseni molding yehungwaru inopfekekaceramic kutaridzika zvikamuvari:
Inogona kuva pedyo nemambure ekuumba geometry yakaoma uye ine zvakakosha zvinodiwa zvezvikamu zviduku zveceramic, yakakwirira chaiyo yekuumba zvigadzirwa, yunifomu yegirini density, simba guru, sintered body performance uye chigadzirwa chemhando kuwirirana kwakanaka, kuitira kuti sintered ceramic zvigadzirwa pasina machining kana kushoma kugadzirisa, kuitira kuderedza mari inodhura yekugadzira ceramic;
Iyo yekuumba maitiro ine yakakwira dhigirii yemakanika uye otomatiki, kutenderera kutenderera kupfupi, manejimendi uye kutonga kwemaitiro ekugadzira zvakare ari nyore kwazvo, nyore kuwana kugadzirwa kwemazhinji, kugadzirwa kwakakura;
Zvigadzirwa zveceramic zvakaumbwa zvine yakanyanya kukwirira dimensional kurongeka uye kupera kwepamusoro, kupera kwepamusoro kunogona kusvika 5um. Naizvozvo,CIM ceramic jekiseni rekugadzira tekinorojiyave imwe yenzira dzekuumba dzeiyo iripo ceramic kugadzira tekinoroji.
