I-ISBM
Lokhu kunezindlela ezimbili eziyinhloko ezehlukene, okungukuthi inqubo yesigaba esisodwa nesigaba esimbili. Inqubo yesigaba esisodwa iphinde yehlukaniswe yaba imishini yesiteshi esine-3 kanye nesiteshi esine-4 Enqubeni yezinqubo ezimbili zomjovo wokunwebeka komjovo (ISBM), ipulasitiki iqale ibunjwe ibe yi "preform" kusetshenziswa inqubo yokubumba umjovo. Lawa ma-preform akhiqizwa ngezintamo zamabhodlela, kufaka phakathi imicu ("ukuphela") ngakolunye uhlangothi. Lawa ma-preform afakwa emaphaketheni, bese ondliwa ngokuhamba kwesikhathi (ngemuva kokupholisa) kumshini wokubumba wokuphinda usebenzise kabusha. Enqubeni ye-ISB, ama-preforms ayashiswa (imvamisa kusetshenziswa ama-infrared heater) ngaphezu kokushisa kwengilazi yabo yokushintshwa, bese kushaywa kusetshenziswa umoya ophakeme kakhulu ube ngamabhodlela kusetshenziswa isikhunta segalelo lensimbi. I-preform ihlala yelulwa ngenduku eyinhloko njengengxenye yenqubo.
Izinzuzo: Kukhiqizwa amanani aphezulu kakhulu. Umkhawulo omncane ekwakhiweni kwamabhodlela. Ukulungiswa kungathengiswa njengento eqediwe yokuthi umuntu wesithathu aqhume. Ilungele amabhodlela we-cylindrical, a-rectangular or oval. Ubunzima: Izindleko ezinkulu zamanani amakhulu. Isikhala esiphansi esidingekayo siphezulu, kepha amasistimu we-compact atholakalayo.
Enqubeni yesigaba esisodwa kokubili ukwenziwa kwangaphambi kokushaywa nokushaywa kwamabhodlela kwenziwa emshinini ofanayo. Indlela yakudala yesiteshi se-4 yokujova, ukuvuselela, ukushaya kanye nokukhishwa kubiza kakhulu kunomshini wesiteshi esithathu osusa isigaba sokuphinda usebenzise futhi usebenzise ukushisa okucashile ku-preform, ngaleyo ndlela konga izindleko zamandla ukuvuselela nokunciphisa kwe-3% kumathuluzi . Le nqubo ichaze ukuthi: Cabanga ukuthi ama-molecule angamabhola ayindilinga amancane, uma ehlangana anezikhala ezinkulu zomoya nokuthintana okuncane kwendawo, ngokuqala ngokunweba ama-molecule abheke phezulu bese eshaya ukuze alule ngokuvundlile ukwelulwa kwe-biaxial kwenza ama-molecule abe ukwakheka kwesiphambano. Lezi "ziphambano" zihlangana ndawonye zishiya isikhala esincane njengoba kuthintwa indawo engaphezulu ngaleyo ndlela okwenza okokusebenza kungabi namandla kakhulu futhi kukhulise amandla okuvimba ekugcobeni. Le nqubo ibuye inyuse amandla okulungela ukugcwalisa iziphuzo ezine-carbonated.
Izinzuzo: Efanele kakhulu amavolumu aphansi nokugijima okufishane. Njengoba preform ingakhishwa ngesikhathi sayo yonke inqubo ungqimba lodonga lwe-preform lungakheka ukuze kuvunyelwe ngisho nobukhulu bodonga lapho lushaya bobumba obuxande futhi obungesilo oluyisiyingi.
Okubi: Imikhawulo ekwakhiweni kwebhodlela. Isisekelo se-champagne kuphela singenziwa emabhodleleni e-carbonated.
