I-PET Blowing Mold

1. Inkqubo yokubumba ngesivuthuvuthu

Iibhotile zePET zihlala ziveliswa kusetyenziswa inkqubo yokubumba ngombhobho enamanyathelo amabini. Ukusuka kwi-preform ukuya kwibhotile egqityiweyo, le nkqubo ibandakanya ukufudumeza, ukuvala umbhobho, ukubumba ngombhobho owoluliweyo, ukubumba, kunye nokugubungula. Nangona inokubonakala ilula, ifuna ulawulo oluchanekileyo lobushushu, uxinzelelo lomoya, kunye nexesha.

Phakathi kwala manyathelo, inqanaba langaphambi kokuvuthela linqaku elibalulekileyo kule nkqubo. Ukuvuthela kuqala njengoko intonga yokwelula isiya ezantsi, ivumela i-preform ukuba ithathe imo yokuqala kwaye iyilungiselele ukuvuthela okulandelayo ngoxinzelelo oluphezulu. Okona kulungileyo, ibhotile emva kokuvuthela kufuneka ibe nemo efana ne-spindle, enceda ukuqinisekisa ukusasazwa kwezinto ezifanayo.

Ukuba kuvela imo ye-dumbbell okanye imo engacwangciswanga, kudla ngokubonisa ukufudumeza okungalinganiyo okanye iiparameters ezingafanelekanga zokuvuthela ngaphambi kokuba zivuthele. Kwiimeko ezinjalo, iindawo zobushushu okanye useto loxinzelelo lomoya kufuneka zilungiswe ngokukhawuleza. Ubungakanani beebhotile ezahlukeneyo buneemfuno ezahlukeneyo zokuvuthela ngaphambi kokuba zivuthele. Umzekelo, iibhotile ezinomthamo omkhulu zihlala zifuna uxinzelelo oluphantsi lokuvuthela ngaphambi kokuba zivuthele, ngelixa iinkqubo zemveliso ezikhawulezayo zifuna uzinzo olukhulu loxinzelelo.

Lilonke, ulawulo oluzinzileyo lwesigaba sangaphambi kokuvuthela lubalulekile ekuqinisekiseni ukuhambelana kwemveliso kunye nesantya esiphezulu semveliso.

2. Indima yeBlow Mold

Ngexesha lenkqubo yokubumba ngokuvuthuza, isikhunta asimiseli nje kuphela imo yangaphandle yebhotile kodwa sikwachaphazela ngokuthe ngqo ukusebenza kakuhle kwemveliso kunye nokuzinza kwemveliso. Isikhunta sokubumba esisemgangathweni ophezulu sibonelela ngolawulo oluchanekileyo lobukhulu kwaye, ngoyilo olupholileyo oluphuculiweyo, sinciphisa umjikelo wokubumba, sivumela izixhobo ukuba zisebenze ngokufanelekileyo nangokungaguquguqukiyo. Ukuba isikhunta asinazo iinkcukacha okanye sinoyilo olungafanelekanga lwesakhiwo, sinokukhokelela ekuguquguqukeni, ubukhulu bodonga obungalinganiyo, okanye kwimveliso engaguqukiyo. Ke ngoko, isikhunta asisosixhobo sokwenza nje kuphela, kodwa siyinxalenye ebalulekileyo yenkqubo yonke yemveliso.

3. Indlela yokukhetha umthengisi weBlow Mold

Ukukhetha umthengisi ofanelekileyo akupheleli nje kwixabiso—kufuna uvavanyo olupheleleyo lwezakhono. Okokuqala, cinga ngamava kunye nobuchule bobuchwephesha. Abavelisi abagxile ixesha elide kwi-PET blow molds badla ngokuba nokuqonda okunzulu kweempawu zezinto kunye neenkcukacha zenkqubo, nto leyo ebenza bakwazi ukuphepha iingxaki ezininzi kwinqanaba loyilo.

Okwesibini, vavanya izixhobo kunye nokukwazi ukuvelisa. Iinkuni ezikumgangatho ophezulu zihlala zenziwe ngee-alloys ze-aluminium eziphezulu okanye intsimbi enamandla aphezulu, zidityaniswe nomatshini ochanekileyo. Oku kuchaphazela ngokuthe ngqo ubomi benkuni kunye nozinzo lwemveliso.

Ukongeza, ubuchule bokwenza ngokwezifiso bubalulekile. Kwiindlela ezikhethekileyo zoyilo lweebhotile okanye iimfuno zokusebenza, nokuba umthengisi angabonelela ngeengcebiso zokulungisa kuya kuba nefuthe elikhulu ekusebenzeni kwemveliso yokugqibela. Okokugqibela, inkxaso emva kokuthengisa akufuneki ijongwe. Iinkuni ngokungathandabuzekiyo zifuna ukugcinwa kunye nokulungiswa ngokuhamba kwexesha, kwaye isantya sokuphendula komthengisi kunye nenkxaso yobugcisa zihlala zigqiba ukuba imveliso ingasebenza kakuhle na.
