Ukubumba ukuvuthela, okwakwaziwa njengokubumba umngxuma wokuvuthela, kukukhula ngokukhawuleza kweplastiki.Inkqubo yokubumba ukuvuthela NgeMfazwe Yehlabathi II, amavili avuthelweyo aqale asetyenziselwa ukuvelisa iingqayi zepolyethylene ezixinene kancinci.Ngasekupheleni kweminyaka yee-1950, kunye nokuzalwa kwe-polyethylene ephezulu kunye nokuphuhliswa koomatshini bokubumba, iteknoloji yokubumba i-vuthela e-Kunshan yayisetyenziswa ngokubanzi.Umthamo wezikhongozeli ezingenanto unokufikelela kumawaka eelitha, kwaye enye imveliso yamkela ulawulo lwekhompyutha.Iiplastiki ezifanelekileyo ukubumba ukubetha zibandakanya i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njl.
Ngokwendlela yokuvelisa i-parison, ukubumba ukuvuthela kunokwahlulwa ku-extrusion blow blowing kunye ne-injection blow blowing.Ezi zisanda kuphuhliswa ziquka ukubunjwa kwe-multi-layer blow and stretch blow molding.I-tubular parison yeplastiki efunyenwe nge-extrusion okanye ukubunjwa kwenaliti ye-thermoplastic resin ifakwe kwi-mold ye-thermoplastic ngelixa ishushu (okanye ishushu kwisimo esithambileyo), kwaye umoya ocinezelweyo ungeniswa kwi-parison ngokukhawuleza emva kokuba umngundo uvaliwe ukuvuthela i-parison yeplastiki. .Yandisa kwaye inamathele ngokusondeleyo kudonga lwangaphakathi lwesikhunta, kwaye emva kokupholisa kunye nokudiliza, iimveliso ezahlukeneyo ezingenanto zifunyenwe.Inkqubo yokwenziwa kwefilimu evuthelweyo ifana kakhulu nomgaqo wokuvuthela ukubunjwa kweemveliso ezingenanto, kodwa ayisebenzisi i-mold.Ngokombono wokuhlelwa kweteknoloji yeplastiki, inkqubo yokubumba ifilimu evuthelweyo iqukwa ngokubanzi kwi-extrusion.Inkqubo yokubumba isivuthe ekuqaleni yayisetyenziselwa ukuvelisa iibhotile ze-polyethylene eziphantsi ngexesha leMfazwe Yehlabathi yesiBini.Ngasekupheleni kwee-1950, kunye nokuzalwa kwe-polyethylene ephezulu kunye nokuphuhliswa koomatshini bokubumba, iteknoloji yokubumba yayisetyenziswa ngokubanzi.Umthamo wezikhongozeli ezingenanto unokufikelela kumawaka eelitha, kwaye enye imveliso yamkela ulawulo lwekhompyutha.Iiplastiki ezifanelekileyo ukubumba ukubetha zibandakanya i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polyester, njl.
