Zingaki izimbotshana ezivame ukuba nezimbotshana ze-PET preform injection?

Amanani we-PET preform mold mold cavity ayalinganiswa futhi ahlelwe ngokwezinga lokukhiqiza, uhlobo lomkhiqizo, kanye nezimfuno zokukhishwa kwekhasimende, ngokulungiselelwa komkhakha ojwayelekile okuhlanganisa 16, 24, 32, 48, 64, futhi 96 imigodi, okuhlanganisa zonke izimo zokukhiqiza kusukela ekukhiqizeni isilingo seshabhu encane ukuya ekukhiqizeni okukhulu okuzenzakalelayo kwefekthri. Ubuningi bomgodi ngamunye buhambisana nethoni yomshini efanisiwe, isikhathi somjikelezo, kanye nokusebenza kahle kokukhiqiza, ukwakha uhlelo oluvuthiwe lokufanisa izimboni.

I 16-isikhunta somgodi ukucushwa kwezinga lokungena okuyisisekelo, ikakhulukazi ezifanele izimboni ezincane zokucubungula, amabhizinisi amasha okuqala, kanye namakhasimende anama-oda enziwe ngokwezifiso amaqoqo amancane namaqoqo amaningi. Ivamise ukufaniswa nemishini yokubumba yomjovo engu-200T–250T, nesikhathi somjikelezo ozinzile samasekhondi ayi-10–15, Izindleko zokutshala izimali eziphansi, ukushintshwa kwesikhunta esiguquguqukayo, kanye nobunzima bokulungisa obuphansi, ezingahlangabezana nezidingo zokukhiqiza zama-oda amancane amabhodlela amanzi amaminerali, amabhodlela amakhemikhali nsuku zonke anobubanzi obuncane, namabhodlela eziphuzo.

I 24-umgodi kanye nesikhunta se-32-cavity izimiso ezijwayelekile ezidume kakhulu emakethe, okuphathelene nokucaciswa kokukhiqiza kwevolumu emaphakathi. Ifaniswe nemishini ye-servo enesivinini esikhulu engu-270T–380T, isikhathi sabo somjikelezo singalawulwa ngokuzinzile kumasekhondi angu-8-12. Lezi zindleko ezimbili zokucushwa kwebhalansi yempahla, okukhiphayo, nezinga lokuhluleka, ukugwema ukusebenza kahle okuphansi kokubunjwa kwe-low-cavity kanye nengozi ephezulu yokugcinwa kwesikhunta esiphezulu se-ultra-high-cavity. Zisetshenziswa kabanzi ekukhiqizeni ngobuningi bama-preforms ajwayelekile wamanzi amaminerali, preforms isiphuzo carbonated, kanye preforms ibhodlela juice izithelo, futhi ziyinketho ekhethwayo yezimboni eziningi zokucubungula i-preform ephakathi nendawo.

I 48-umgodi kanye nesikhunta se-64-cavity ziyingxenye yezinhlelo zokukhiqiza ngobuningi ezisebenza kahle kakhulu, idinga imishini ye-450TT yobungcweti ye-preform enesivinini esiphezulu enokuqina okuphezulu nokunemba. Lezi zibunjwa zifanele abakhiqizi abakhulu abanama-oda amakhulu azinzile kanye nezidingo eziphezulu zokukhipha nsuku zonke. Isikhathi somjikelezo esizinzile samasekhondi angu-9–11, umkhiqizo wabo wansuku zonke womshini owodwa uphakeme kakhulu kunesikhunta se-medium-cavity, kunciphisa kakhulu izindleko zokukhiqiza kanye nokwenza ngcono ukuncintisana ezimakethe.

I 96-isikhunta se-ultra-high-cavity iwukucushwa kwezimboni ezisezingeni eliphezulu, ifaniswe ne-600T nangaphezulu kwemishini emikhulu egcwele isivinini esiphezulu esizenzakalelayo, isetshenziselwa kuphela ukukhiqizwa kwe-preform esezingeni eliphakeme kakhulu yama-oda asekela imboni yesiphuzo kanye nemboni yamanzi. Nakuba isikhunta se-ultra-high-cavity sinokukhipha okuphezulu kakhulu, banezidingo eziphezulu zokunemba komshini, ukuzinza kwesistimu yokupholisa, kanye nezinsiza ezikhona endaweni, ngezindleko eziphakeme zokutshalwa kwempahla kanye nokugcinwa kwazo, futhi awafanele amafekthri amancane naphakathi nendawo. Ngaphezu kwalokho, umthamo we-cavity nawo udinga ukufaniswa nokucaciswa komkhiqizo: ama-preform ebhodlela anomlomo obanzi anobubanzi obukhulu, uwoyela ibhodlela preforms, kanye nama-preforms wesitsha esinomthamo omkhulu awafanele ukubunjwa okunezimbotshana eziphezulu ngenxa yomthamo wazo omkhulu wesiqephu esisodwa., futhi ngokuvamile yamukela ukulungiselelwa komgodi okungu-16–32.

Amakhasimende angakhetha inani elifanele lesikhunta ngokuya ngokuzinza kwe-oda lawo, amagoli okukhipha nsuku zonke, kanye nesabelomali sokuzuza inzuzo engcono kakhulu yokukhiqiza.
