1. Extrusion blow molding
Extrusion blow molding ndiyo imwe yedzakanyanya kushandiswa nzira dzepurasitiki yekurongedza midziyo.Iyo poda (kana granular material) ye thermosetting plastic inonyungudutswa kuburikidza ne extruder, yozoitwa inopisa-inonyunguduka tubular parison zvinoenderana neakakosha zvinhu chubhu.Kana jeri rinopfuura kureba kwakagadzirirwa, pariso inopinda muforoma, mold inovharwa, yobva yaputika.
Hunhu hweiyi nzira yekuumba ndeiyi: kukwirira kwekugadzira kugadzira, kudziya kweparison kwakadzikama, yakafara inobvumidzwa mhando yechimiro, saizi uye kukora kwemadziro echigadziko chine gomba, kuchinjika kwakasimba, kusimba kwakanyanya kwekumanikidza kwekuputira maitiro, nyore muchina nemidziyo, uye yakaderera. engineering investment.Zvisinei, kururama kwemaoko emaoko hakuna kukwirira.Mukati memukati weshinda yekunze uchashanduka nekushanduka kweshinda yekunze pamusoro.Pane patchwork seam pazasi pemudziyo.
2. Injection blow molding
Jekiseni blow molding inoshandisa muchina wepurasitiki kubaya jeri mu mandrel.Mushure mekunge jeri racho ratonhodzwa zvine mwero, mandrel uye parison zvinodyiswa mumudziyo wekuputira.The blow molding tool inotsikirira mandrel uye mhepo yakaunzwa yakavharwa uye yakamanikidzwa kuitira kuti Parison iwedzere uye ibudise mabasa emaoko anodiwa, uye zvinhu zvinobviswa mushure mekuiswa mufiriji uye kusimbiswa.
Hunhu hweiyi nzira yekuumba: hapana seams mumhizha, hapana chikonzero chekuzogadziridzwa gare gare, yakanyanya kurongeka yetambo dzekunze uye zvivhariso zvemabhodhoro, mukati memukati wemusoro nemutsipa uri padenderedzwa rakatsetseka, kugona kwekugadzira kunogona kuve. hombe, kune mashoma ebetsero muchina nemidziyo, uye kusimba kwesimba repasi pechigadzirwa Kukwirira, kuderera kwekushandisa kwezvinhu, yunifomu yemadziro ukobvu, uye yakakwirira kugadzira.Nekudaro, iyo mari mumapurojekiti emidziyo yemuchina yakakura, kutenderera kwekugadzira kwakareba, zvinodikanwa zvevanoshanda zvinoshanda zvakakwira, chitarisiko hachifanirwe kunge chakaomarara, uye midziyo yemidziyo ishoma, saka yakakodzera kugadzira diki nepakati. midziyo yemhando yepamusoro.
3. Stretch blow molding
Iyo nzira yekuumba ndeye kushandisa tambo yakatambanudzwa kuita radial kutambanudza uye wobva wangoita kuvhuvhuta.Mukuwedzera, panguva yekugadzira, biological macromolecules yakarongeka yakagadziriswa pamadziro emifananidzo, nokudaro inovandudza zvikuru kushanda kwepurasitiki.
Hunhu hweiyi nzira yekuumba ndeiyi: yakaderera chirema, yakakwira kugadzirwa kwehunyanzvi, kutonga kuri nyore kwehuremu hwemambure, kuomarara kwepamusoro, kusimba kwakagadziridzwa, kuenderana uye kutsetseka kwemaoko, uye yakanaka chipingamupinyi uye chisimbiso zvivakwa, asi tembiricha yekudzora zvinodiwa pakutambanudza. dzakakwirira, uye mari mumichina nemidziyo yakakura.
