Zvinoenderana nemaitiro ekugadzira jeri, kuvhuvhuta kuvhuvhuta kunogona kukamurwa kuita extrusion blow molding uye jekiseni kuvhuvhuta.Iwo achangobva kugadzirwa anosanganisira akawanda-layer blow molding uye stretch blow molding.Ndeupi musiyano uripo pakati pezvivakwa zviviri izvi?
Extrusion, inozivikanwawo se extrusion blow molding, inzira yekushandisa extruder (extruder) kupfuudza zvakatevedzana resin inopisa kuburikidza nefa kuti ibudise chigadzirwa chechimiro chaunoda.Extrusion zvakare dzimwe nguva inoshandiswa mukuumbwa kwe thermosets uye inogona kushandiswa mukuumbwa kwemapurasitiki ane furo.
Chakanakira extrusion blow molding ndechekuti inogona kuburitsa zvigadzirwa zvemhando dzakasiyana siyana, nepamusoro pekugadzira hunyanzvi, uye inogona kuve otomatiki uye inoenderera kugadzirwa;chakashata ndechekuti thermosetting mapurasitiki haagone kugadziridzwa nenzira iyi, uye saizi yechigadzirwa inotarirwa kuita.
Jekiseni molding inozivikanwawo sejekiseni blow molding.Jekiseni molding inzira yekushandisa jekiseni rekuumba muchina (kana jekiseni muchina) kubaya thermoplastic kunyunguduka muforoma pasi pekumanikidzwa kukuru, uye wozotonhorera nekuomesa kuti uwane chigadzirwa.Jekiseni molding inogona zvakare kushandiswa kuumba thermosets uye furo.
Zvakanakira zvekuumbwa kwejekiseni ndezvekuti kumhanya kwekugadzira kuri kukurumidza, kushanda kwacho kwakakwira, mashandiro acho anogona kuita otomatiki, uye anogona kugadzira zvikamu zvine maumbirwo akaomarara, ayo anonyanya kukodzera kugadzirwa kwakawanda.Izvo zvakashata ndezvekuti mutengo wemidziyo uye mold wakakwira, uye kuvharwa kwemajekiseni ekuumba michina kwakaoma.
Blow molding inonziwo hollow blow molding kana hollow molding.Blow molding inzira yekuisa mweya weparison inopisa yakavharwa muforoma kuita mugomba chigadzirwa kuburikidza nekumanikidza kwemweya wakadzvanywa.Blow molding inosanganisira nzira mbiri dzekufuridza firimu uye kuvhuvhuta maburi zvigadzirwa.Zvigadzirwa zvemafirimu, mabhodhoro akasiyana-siyana, mbiya, jugs uye matoyi evana anogona kugadzirwa nekuputira kuumba.
Semuyenzaniso, nei bhodhoro richingogona kushandisa bhodhoro rekuumba, asi richigona kushandisa jekiseni kuumba?Chikonzero ndechekuti nzvimbo yemukati yebhodhoro yakakura uye muromo webhodhoro idiki, saka iyo jekiseni yekuumba core haigone kubviswa.Naizvozvo, vhuvhuta vanogadzira sandwich iyo purasitiki yakapfava inonyunguduka pakati peforoma uye kuifuridza kuti iite kuti inamatire kumadziro emukati meforoma pasina kushandisa core.
