Muchina wekugadzira jekiseni unoshandiswa kuumba jekiseni nesimbi mold, umo mold yakanzi ine mhango ine mhango mune yezasi mold uye yepamusoro mold, umo chiteshi chinoumbwa panzvimbo yakafanotemerwa mugomba rezasi mold pedyo ne mupinyi wekupinza resin yakanyungudutswa (P) mugomba.Mazariro ematanho akavharwa zvachose, achigadzira nzira inotonhorera yepakati yekuyerera kuitira kuti inotonhorera yepakati (eg mhepo inotonhorera) inopinzwa mugomba, inoyerera nemumigero uye inoburitswa kubva mukubuda.Iyo yepasi uye yepamusoro mold inogadzirwa nealuminium kana aluminium alloy.Nzvimbo dzakasarudzwa dzegomba, dzinosangana zvakananga neresin yakanyungudutswa, inoputirwa nejecha kana kuti inobatwa nemakemikari kuti igadzire mapundu madiki.
Metal Powder Injection Molding (MIM) ihupfu hutsva hwesimbi padyo-net-shape tekinoroji iyo iri kuunza yemazuva ano jekiseni repurasitiki rekuumba kuita simbi yehupfu.
Metal mold inoratidzwa pazasi:
Maitiro acho ndeaya anotevera: Pakutanga, hupfu hwakasimba uye organic binder zvakasanganiswa zvakafanana, zvobva zvapinzwa mugomba nemushini wekuumba jekiseni pasi pemhepo inopisa yepurasitiki (~ 150 ℃), uye ipapo binder mune yekuumba isina chinhu inobviswa. makemikari kana thermal decomposition nzira, uye pakupedzisira chigadzirwa chekupedzisira chinowanikwa ne sintering uye densification.Maitiro: binder → kusanganisa → kugadzira jekiseni → kudzikisa mafuta → sintering → mushure mekurapwa.
Iyo jekiseni mold chishandiso chekugadzira zvigadzirwa zvepurasitiki uye ndiyo vimbiso yechimiro chazvo chakakwana uye hukuru chaihwo.Jekiseni molding inzira yekugadzirisa inoshandiswa mukugadzirwa kwehuwandu hwemamwe maumbirwo akaomarara.Inonyatso reva jekiseni rezvinhu zvakanyungudutswa-zvinopisa (nekumanikidza kwakanyanya mugomba, mushure mekutonhodzwa nekurapa, kuti uwane chigadzirwa chakaumbwa. Metal poda jekiseni muchina wekushandisa simbi poda jekiseni rekugadzira tekinoroji yekuumba michina. Kune zvakare michina ine Yakasiyana-siyana.Process flow binder raw materials kuomesa – muhopi – jekiseni kuumba – inotonhora mumhanyi (hot runner) – raw edge treatment.
