Yonke inkqubo yokuvelisa iibhotile ezibunjiweyo (ukuthatha inyathelo elinye lokubumba i-injection stretch blowing njengomzekelo)
Umgaqo oyintloko kukufaka i-parison kwi-parison uze uyisolule ngoko nangoko kwaye uyivuthele kwi-mold efanayo kumatshini omnye. Le ndlela ifanelekile kakhulu ekwenzeni iibhotile zamanzi ze-PET zeminerali kunye neebhotile zeziselo ezisebenza kakuhle.
Inyathelo 1: Ukulungiswa kwezinto eziluhlaza kunye nonyango lwangaphambi kokuba zisetyenziswe
Eyona nto isetyenziswa kakhulu yiPET (polyethylene terephthalate), kwaye ikwasebenza nakwiPP, PC, njl.

Ukomisa: Izinto ezisetyenziswa kwi-PET zinamandla okucoca kwaye kufuneka zomiswe ngokungqongqo kubushushu obuphezulu (njenge-150-180℃) kusetyenziswa isixhobo sokomisa esisusa umswakama ukuze kuncitshiswe umswakama ukuya kwinqanaba eliphantsi kakhulu (njengengaphantsi kwe-0.005%). Le yeyona nto ibalulekileyo ekuqinisekiseni ukuba ibhotile ibonakala ngokucacileyo kwaye ayiqhekeki.

Inyathelo lesi-2: Ukubumba i-parison ngenaliti
Iipellets zePET ezomileyo zifunxwa kwibharele yomatshini wokubumba inaliti kwaye zifudunyezwe kwaye zenziwe iplastiki zibe kwimeko yokunyibilika.

Ukunyibilika kufakwa kwi-parison mold ngesikrufu se-injection ukuze kwenziwe i-parison ebonakalayo efana netyhubhu yovavanyo.

Inxalenye yomlomo webhotile ye-parison yenziwe ngokupheleleyo kwaye ifikelele ekuchanekeni kokugqibela kwesi sigaba.

Inyathelo lesi-3: Uhlengahlengiso lobushushu be-parison
I-hot parison eyenziweyo idluliselwa kwisikhululo sokulawula ubushushu. Ngexesha lale nkqubo, i-parison ipholiswa ngokulinganayo ukuya kuluhlu lobushushu olufanelekileyo olufaneleke kakhulu ukolulwa (malunga ne-90-110℃). Ukufana kobushushu ngundoqo wokuqinisekisa umgangatho wokubunjwa okulandelayo.

Inyathelo lesi-4: Ukolula kunye nokufutha i-molding
Eli lelona nyathelo libaluleke kakhulu, eligqitywa ngaphakathi kwesikhunta sokubumba.

Ukolula okude: Isikhunta sokubumba esivuthuzayo siyavalwa, kwaye kufakwa intonga yokusonga ukusuka phezulu ukuya ezantsi kwi-parison ukuze yolule ngokude ukuya ezantsi kwesikhunta.

Ukuvuthela ngoxinzelelo oluphezulu: Kwangaxeshanye, umoya oxinezelekileyo (ngesiqhelo i-20-40 bar) uvuthela usuka phezulu kwintonga yokunweba, uvuthela iparlet ecaleni njengebhaluni kwaye unamathele ngokuqinileyo eludongeni lwangaphakathi lwesikhunta sokubumba esibandayo.

Inyathelo lesi-5: Pholisa kwaye ubeke
Ibhotile igcinwa iphantsi koxinzelelo kwi-blow mold kwaye ipholiswe imizuzwana embalwa ukuze ilungise imo yayo. Iindlela zamanzi ezipholileyo ngaphakathi kwi-mold ziya kususa ubushushu ngokukhawuleza.

Inyathelo lesi-6: Vula isikhunta uze usisuse
I-blow mold mold iyavulwa, kwaye iibhotile ezenziweyo zikhutshwa ngesandla somatshini kwaye zithunyelwe kwiinkqubo ezilandelayo.

Inyathelo lesi-7: Ukuhlolwa komgangatho emva kokucubungula
Ukusika: Susa ifleshi engaphezulu (isiphatho sezinto) emlonyeni webhotile.

Ukufunyanwa

Ukuchonga umthamo: Qinisekisa ukuchaneka kobungakanani bokuzalisa.

Uvavanyo lokusebenza kokutywina: Jonga ukuba ubungakanani bomlomo webhotile kunye nomsonto ziyafaneleka na.

Ukuchonga ubukhulu bodonga: Sebenzisa i-ultrasound thickness gauge ukuqinisekisa ukuba ubukhulu bomzimba webhotile buyafana, ingakumbi ezantsi nasemagxeni.

Uvavanyo loxinzelelo: Kwiibhotile zesiselo ezinekhabhoni, kufuneka uvavanyo lokumelana noxinzelelo lwangaphakathi.
