1. Extrusion blow molding
Extrusion blow molding ke e 'ngoe ea mekhoa e sebelisoang haholo bakeng sa lijana tsa polasetiki.Phofo (kapa granular material) ea polasetiki ea thermosetting e qhibiliha ka extruder, ebe e etsoa ka parison ea hot-melt tubular ho ea ka tube e khethehileng ea thepa.Ha parison e feta bolelele bo behiloeng esale pele, parison e kena ka har'a hlobo, hlobo e koetsoe, ebe e bōptjoa.
Litšobotsi tsa mokhoa ona oa ho bopa ke: ts'ebetso e phahameng ea tlhahiso, mocheso o leka-lekaneng oa parison, mefuta e mengata e lumelletsoeng ea sebopeho, boholo le botenya ba lebota la sekoti se sekoti, ho ikamahanya le maemo ho matla, matla a phahameng a khatello ea ts'ebetso ea ho bopa, mochini o bonolo le lisebelisoa, le tse tlase. matsete a boenjiniere.Leha ho le joalo, ho nepahala ha mosebetsi oa matsoho ha ho holimo.Sebaka se ka hare sa khoele e ka ntle se tla fetoha ka phetoho ea khoele e ka ntle holim'a metsi.Ho na le seam sa patchwork ka tlase ho setshelo.
2. Ente blow molding
Ente blow molding sebelisa mochine oa polasetiki ho enta parison ka mandrel.Ka mor'a hore parison e pholisoe ka mokhoa o itekanetseng, mandrel le parison li kenngoa ka har'a sesebelisoa sa ho bopa.Sesebelisoa sa ho phunya se hatella mandrel le moea o hlahisoang o koetsoe le ho hatelloa e le hore The parison e atolohe 'me e hlahise mesebetsi ea matsoho e hlokahalang,' me thepa e tlosoa ka mor'a hore e be sehatsetsing le ho tiisa.
Litšobotsi tsa mokhoa ona oa ho bōpa: ha ho na seams mesebetsing ea matsoho, ha ho hlokahale ho nchafatsoa hamorao, ho nepahala ho phahameng ha likhoele tsa ka ntle le li-bottle stoppers, karolo e ka hare ea hlooho le molala e le selikalikoe se boreleli, bokhoni ba tlhahiso bo ka ba teng. e kholo, ho na le mechine le lisebelisoa tse thusang tse fokolang, 'me matla a hatellang a tlase a sehlahisoa a Phahameng, a tlaase a sebelisoa thepa e tala, botenya ba lerako le lekaneng, le katleho e phahameng ea tlhahiso.Leha ho le joalo, matsete a merero ea lisebelisoa tsa mochini o moholo, potoloho ea tlhahiso e telele, litlhoko tsa basebelisi ba sebetsang li phahame, ponahalo ha ea lokela ho ba thata haholo, 'me litlhaloso tsa setshelo li na le moeli, kahoo e loketse ho etsa lihlahisoa tse nyenyane le tse mahareng. lijana tse nepahetseng haholo.
3. Ho otlolla ho bopa
Mokhoa oa ho bopa ke ho sebelisa molamu o otlolohileng ho otlolla radial, ebe hang-hang o etsa ho bopeha.Ho phaella moo, nakong ea ts'ebetso ea ho bōpa, li-macromolecules tsa likokoana-hloko li hlophisitsoe ka mokhoa o hlophisitsoeng maboteng a litšoantšo, kahoo li ntlafatsa haholo ts'ebetso ea sejana sa polasetiki.
Litšobotsi tsa mokhoa ona oa ho bopa ke: sekhahla se tlase se nang le sekoli, ts'ebetso e phahameng ea tlhahiso, taolo e bonolo ea boima ba letlooa, boima bo phahameng ba fracture, ho tiea ho ntlafetseng, ho lumellana ho ntlafalitsoeng le boreleli ba mesebetsi ea matsoho, le thepa e ntle ea thibelo le ho tiisa, empa litlhoko tsa taolo ea mocheso bakeng sa ho otlolla. li batla li phahame, 'me matsete a mechine le thepa a batla a le maholo.
