Ukubumba i-Blow yitekhnoloji yokucubungula esetyenziswa ngokubanzi kwimveliso yeemveliso zeplastiki, ikakhulu kukwenziwa kweenxalenye zeplastiki ezingenanto ezifana neebhotile zeplastiki, izikhongozeli kunye neendawo zemoto. Inkqubo yemveliso ikakhulu ibandakanya amanyathelo amane angundoqo: ukulungiswa kwemathiriyeli ekrwada, i-extrusion okanye i-injection preforming, ukubumba ukuvuthela, kunye{1}}nokulungiswa kweposi.
Okokuqala, ngexesha lokulungiswa kwezinto eziluhlaza, i-resin yeplastiki efanelekileyo kufuneka ikhethwe ngokusekelwe kwiimfuno zemveliso. Imizekelo eqhelekileyo ibandakanya i-polyethylene (PE), i-polypropylene (PP), kunye ne-polyethylene terephthalate (PET). Izinto eziluhlaza zongezwa ngokuqhelekileyo kwindlela yokomisa kwifom ye-pellet ukususa umswakama kunye nokuqinisekisa umgangatho wokubumba.
Okulandelayo kuza inqanaba lokulungisa, elahlulwe ikakhulu laziindlela ezimbini: ukubumba ukuvuthela kwe-extrusion kunye ne-injection blow blowing. Kwi-extrusion blow blowing, iipellet zeplastiki ziyafudunyezwa kwaye zinyibilike kwi-extruder kwaye emva koko zikhutshelwe kwisetyhula ukuze zenze i-tubular parison (eyaziwa ngokuba yi "preform"). Ekubunjweni kokuvuthela ngesitofu, i-parison ilungiselelwa kwangaphambili kusetyenziswa inkqubo yokubumba inaliti kwaye ikhuselwe kubumba lokuvuthela.
Ukubumba ukuvuthela linyathelo eliphambili. Emva kokuba i-parison ifudunyezwe kwiqondo lobushushu elifunekayo, umoya ocinezelweyo ufakwa kwi-parison, ubangele ukuba uhambelane neendonga zokungunda kwaye wandise ukumila. Inkqubo yokupholisa yokungunda emva koko isebenze, ivumela iplastiki ukuba iqine ngokukhawuleza kwaye isete. Ukungunda emva koko kuyavuleka, kwaye imveliso egqityiweyo iyakhutshwa. Le nkqubo idinga ulawulo oluchanekileyo lobushushu, uxinzelelo, kunye nexesha lokupholisa ukuze kuqinisekiswe ubukhulu bodonga obufanayo kunye nokuzinza kwe-dimensional.
Okokugqibela, ulungiso lweposi - luyenzeka, luquka ukucheba, ukususwa kweflash, ushicilelo, kunye nokuleyibheli, ukuqinisekisa ukuba imveliso ihlangabezana neemfuno zobuhle kunye nokusebenza. Ezinye iimveliso ezifunwayo zikwafuna uvavanyo, olufana nokulinganisa ubukhulu bodonga kunye novavanyo lwetywina, ukuqinisekisa ukuba ziyahlangabezana nemigangatho yomgangatho.
Inkqubo yokubumba isivuthelo, ngenxa yokusebenza kakuhle kwayo, ubhetyebhetye, kunye nokufaneleka kwemveliso{0}}enkulu, idlala indima ebalulekileyo kumashishini afana nokupakishwa, ezonyango, kunye neemoto. Umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso kunokuphuculwa ngakumbi ngokulungiselela iiparamitha zenkqubo kunye noyilo lokungunda.
