Mochini o fehlang botlolo ke mochini o ka phetlelang li-preforms tse felileng ka libotlolong ka mekhoa e itseng ea thekenoloji.Hona joale, boholo ba mechine ea ho phunya e sebelisa mokhoa oa ho letsa mehato e 'meli, ke hore, preheating - blowing molding.
1. Ho futhumatsa pele
Preform e khabisoa ka lebone le phahameng la mocheso ho futhumatsa le ho nolofatsa 'mele oa preform.E le ho boloka sebōpeho sa molomo oa botlolo, molomo oa preform ha o hloke ho futhumala, kahoo ho hlokahala sesebelisoa se itseng sa ho pholile ho se pholisa.
2. Ho bopa ho foka
Mokhahlelo ona ke oa ho beha preheated preform ka har'a hlobo e lokiselitsoeng, ho e kenya ka khatello e phahameng, ebe o letsa preform ka botlolong e lakatsehang.
The blow molding process ke mokhoa oa ho otlolla ka litsela tse peli, moo liketane tsa PET li atolosoang, li shebiloe le ho hokahana ka mahlakoreng ka bobeli, ka hona ho eketsa thepa ea mochini oa lebota la botlolo, ho ntlafatsa ho tsikitla, ho tsitsipana le matla a ts'usumetso, le ho ba le tshebetso e phahameng haholo.Ho tiisa moea o motle.Le hoja ho otlolla ho thusa ho ntlafatsa matla, ha hoa lokela ho otlolloa haholo.Karolelano ea ho otlolla e lokela ho laoloa hantle: tataiso ea radial ha ea lokela ho feta 3.5 ho 4.2, 'me tataiso ea axial ha ea lokela ho feta 2.8 ho 3.1.Botenya ba lerako la preform ha boa lokela ho feta 4.5mm.
Ho foka ho etsoa pakeng tsa mocheso oa phetoho ea khalase le mocheso oa crystallization, ka kakaretso o laoloang pakeng tsa 90 le 120 degrees.Letotong lena, PET e bonts'a boemo bo holimo ba elastic, 'me e fetoha botlolo e bonaletsang ka mor'a ho bopeha ka potlako, ho pholile le ho beha.Ka mokhoa oa mohato o le mong, mocheso ona o khethoa ke nako ea ho pholile ka mokhoa oa ho bopa ente (joaloka mochine oa ho bopa oa Aoki blowing), kahoo kamano pakeng tsa ente le liteishene tsa ho foka e lokela ho kopanngoa hantle.
Mokhoeng oa ho phunya, ho na le: ho otlolla—kotlo e le ’ngoe—likotlo tse peli.Liketso tse tharo li nka nako e khutšoanyane haholo, empa li tlameha ho hokahanngoa hantle, haholo-holo mehato e 'meli ea pele e khethollang kabo ea kakaretso ea thepa le boleng ba ho foka.Ka hona, hoa hlokahala ho lokisa: nako ea ho qala ea ho otlolla, lebelo la ho otlolla, nako ea ho qala le ea ho qetela ea ho fofa pele, khatello ea pele, lebelo la phallo ea pele, joalo-joalo Haeba ho khoneha, kabo ea mocheso ka kakaretso. ea preform ka laoloa.Mocheso oa mocheso oa lebota le ka ntle.Ts'ebetsong ea ho bopa le ho pholile ka potlako, khatello ea maikutlo e hlahisoang leboteng la botlolo.Bakeng sa libotlolo tsa lino tse nang le carbonate, e ka hanela khatello ea ka hare, e ntle, empa bakeng sa libotlolo tse chesang tse chesang, hoa hlokahala ho netefatsa hore e lokolloa ka ho feletseng ka holim'a mocheso oa phetoho ea khalase.
