Jekiseni molding inzira yekuwana zvigadzirwa zvakaumbwa nekupinza zvinhu zvepurasitiki zvinonyungudutswa nekupisa muforoma, wozozvitonhodza nekuzviomesa.
Iyo jekiseni yekuumba maitiro inoda kushandiswa kwejekiseni rekugadzira muchina, mbishi plastiki zvinhu, uye mold.Purasitiki inonyungudutswa mumushini wekuumba jekiseni yobva yaiswa muforoma, umo inotonhodza nekuomesa muchikamu chekupedzisira.
Maitiro ekuumba jekiseni akakamurwa kuita 4 matanho makuru:
1.Plastification
2.Jekiseni
3.Kutonhorera
4.Demold
Injection Molding inzira yekugadzira yekugadzira zvikamu muhukuru hukuru.Iyo inonyanya kushandiswa muhuwandu-yekugadzira maitiro apo chikamu chimwe chete chiri kugadzirwa zviuru kana kunyange mamirioni enguva mukutevedzana.
Injection Molding process, Yekutanga Danho 1: Chigadzirwa Dhizaini
Dhizaini nderimwe rematanho akanyanya kukosha ekugadzira maitiro nekuti ndiwo mukana wekutanga kudzivirira kukanganisa kunodhura gare gare.Chekutanga, kusarudza zano rakanaka pakutanga kwakakosha, zvakare zvimwe zvinangwa zvakawanda zvinofanirwa kutariswa: basa, aesthetics, manufacturability, kusangana, nezvimwe. Magadzirirwo echigadzirwa anowanzo itwa nekombuta inobatsira dhizaini (CAD) software, (UG) software. .Dzimwe nzira dzakananga dzekudzivirira zvikanganiso zvinodhura panguva yekugadzirwa kwechigadzirwa ndeyekuronga yunifomu yemadziro ukobvu pese pazvinogoneka, uye kuti zvishoma nezvishoma uchinje kubva kune imwe ukobvu kuenda kune imwe kana shanduko mukukora isingadzivisike.Izvo zvakakoshawo kudzivirira kuvaka kushushikana mukati mekugadzira, senge makona ari 90 madhigirii kana pasi.
Injection Molding process, Yekutanga Danho 2: Mold Dhizaini
Mushure mekugadzirwa kwechigadzirwa kwasimbiswa, mold inoda kugadzirirwa kugadzira jekiseni mold.Zviumbwa zvedu zvinowanzogadzirwa kubva kumhando idzi dzesimbi:
1.Simbi yakaomeswa: Simbi yakaomeswa kazhinji ndiyo inogara kwenguva refu inoshandiswa kugadzira mold.
2.Izvi zvinogadzira simbi yakaomeswa sarudzo yakanaka yezvinhu kune zvigadzirwa uko mazana ezviuru ezviuru achagadzirwa.
3.Pre-Hardened steel: Haagari mavhiriji akawanda sesimbi yakaoma, uye haina kudhura kugadzira.
Iyo yakanaka mold dhizaini inoda kutarisisa yakanyatso kuvakwa kwe mold uye yakanaka yekutonhora mutsara.Kutonhorera kwakanaka kunogona kuderedza nguva yekutenderera.Uye nguva shoma yekutenderera inounza mutengi kugadzirwa kukuru, ita mutengi zvakare kukosha mubhizinesi.
