Vuthela Ukubumba: I-Blow Molding iyindlela esheshayo, enekhono yokuhlanganisa izibambi ezingenalutho zama-polymers we-thermoplastic. Izinto ezenziwe kusetshenziswa lo mjikelezo izikhathi eziningi zinezindonga ezincane futhi zifinyelela ngosayizi nokuma kusuka kumajeke amancane, awubukhazikhazi kuya emathangeni kagesi wezimoto. Kulo mjikelezo umumo oyi-cylindrical (parison) owenziwe nge-polymer efudumele utholakala emgodini wefomu elihlukanisiwe. Umoya ube usufakwa ngenaliti egcekeni, enwebeka ukuze uvumelane nesimo somgodi. Izinzuzo zokwenza igalelo zihlanganisa idivayisi ephansi kanye nokukhahlela izindleko zebhakede, amanani okudala okusheshayo kanye nekhono lokubumba izimo eziyinkimbinkimbi ngesiqeshana esisodwa. Ikhawulelwe, noma kunjalo, ekubunjweni okungenalutho noma okuyisilinda.
I-Calender: I-Calender isetshenziselwa ukukhiqiza amashidi namamuvi we-thermoplastic kanye nokufaka izembozo zepulasitiki ngemuva kwezinto ezihlukahlukene. I-Thermoplastics ye-batter efana nokuvumelana ayinakwa futhi nokuqhubeka kwamaroli afudumele noma apholile. Izinzuzo zayo zihlanganisa izindleko ezincane kanye nokuthi izinto zeshidi ezilethwayo ngokuyisisekelo zikhululekile ekubunjweni kokukhathazeka. Kuvinjelwe kumashidi futhi amamuvi amancane kakhulu awasebenzi.
Iyasakaza: Ukusakaza kusetshenziselwa ukuletha amashidi, imigoqo, amashubhu, imidanso yokuqala nokufakwa kanye nokuvikela izingxenye zikagesi. Umjikelezo oyisisekelo, ongadingi amandla angaphandle noma ukungezwani. Umumo ulayishwa ngepulasitiki ewuketshezi (ama-acrylics, ama-epoxies, ama-polyester, i-polypropylene, inayiloni noma i-PVC ingasetshenziswa) bese ifudunyezwa ukuze ilungiswe, ngemva kwalokho i-material iba yi-isotropic (ibe nezakhiwo ezifanayo ngale ndlela nalokhuya). Izinzuzo zayo zifaka: izindleko zomumo ophansi, amandla okwenza uhlaka lwezingxenye ezinkulu ezinamasegimenti aminyene ayisiphambano, ukuqedwa kwendawo ehloniphekile kanye nokunethezeka kwakho kokudala ivolumu ephansi. Ngokudabukisayo, ikhawulelwe emimoyeni eqondile ngokumaphakathi futhi ivamise ukuntula umnotho ngamazinga aphezulu okudala.
Ukubunjwa Kokucindezela: I-Compression Molding isetshenziselwa ukuphatha ama-polymers e-thermosetting. Ishaja elinganiswe ngaphambili, evame ukwakhiwa kusengaphambili ye-polymer ivalwa ngaphakathi kwefomu elivaliwe futhi ivezwa kumfutho nokucindezeleka kuze kube yilapho ithatha isimo somgodi womumo nokulungiswa. Nakuba ubude benqubo bokubunjwa kwengcindezi buyinde ngokuyisisekelo kunaleso sokwenza ukumnika kanye nezingxenye ezisemaceleni amaningi noma ukumelana okusondele kakhulu kuyinselele ukuletha, ijabulela izinzuzo ezimbalwa ezihlanganisa izindleko zendlu yezwe ephansi (i-tooling ne-hardware esetshenziswayo iqonde kakhudlwana futhi engabizi kakhulu), udoti omncane wezinto ezibonakalayo kanye namaqiniso okuthi izingxenye ezinkulu, ezinzima zingalolongwa nokuthi umjikelezo uguquguquka ukuze usheshe usetshenziswe kwikhompyutha.
Ukuxoshwa: Ukukhipha kusetshenziselwa ukuhlanganisa okungami kwefilimu, ishidi, amashubhu, amashaneli, amafaneli, amabha, amaphuzu nemicu kanye namaphrofayili ahlukene nokuhlobene nokubunjwa kokushaywa. I-thermoplastic eyimpuphu noma eyi-granular noma i-thermoset polymer iyanakekelwa isuka esitsheni iyiswa emgqonyeni ofudumele lapho incibilika khona bese ithunyelwa, njengomthetho ngesikulufu se-pivoting, nge-spout enengxenye efanelekile yesiphambano. Ipholiswa ngokuchaphaza kwamanzi bese isisikwa ibe ngobude obufanele. Umjikelezo wokuxoshwa uthambekele ekubhekeni kwezindleko zayo eziphansi zedivayisi, amandla okusingatha izimo zephrofayela eziyinkimbinkimbi, ithuba lokulinganisa ukudalwa okusheshayo kanye namandla okufaka ama-coatings noma amajakhethi phakathi kwezinto (njengezintambo). Ikhawulelwe ezindaweni ezinesiphambano esifanayo, noma kungaba njalo.
Ukubunjwa komjovo:Ukubunjwa komjovoiyindlela evame ukubandakanyeka kakhulu yokwenziwa kwezinto zepulasitiki ngezinga elikhulu ngenxa yamazinga ayo aphezulu okudala kanye nomyalo omkhulu phezu kwezici zezinto. (El Wakil, 1998) Kulelisu, i-polymer inakekelwa isuka esitsheni se-pellet noma esakhiweni esiyimpushana ibe yigumbi lapho ifudunyezwa khona ukuze ibe nezinto ezihlukahlukene. Ibe iphonswa ibe yimbobo ehlukene bese iqina ngaphansi kokushuba, emva kwalokho umumo uyavuleka bese ingxenye idonswa. Izinzuzo zokwakheka kokumnika zingamazinga aphezulu okudala, izindleko eziphansi zomsebenzi, ukukhiqizwa kabusha okuphezulu kwezinto ezicashile eziyinkimbinkimbi kanye nokuqedwa okukhulu kwendawo. Izingqinamba zakhona ziyizinsiza zokuqala eziphakeme futhi zidlulisa izindleko kanye nendlela engasebenzi ngayo ngokwezezimali ekugijimeni okuncane.
Ukubumba Okujikelezayo: I-Rotational Molding ingumjikelezo lapho izinto ezingenalutho zingakhiqizwa kusukela ku-thermoplastics futhi ngezinye izikhathi ama-thermosets. Ishaja ye-polymer eqinile noma ewuketshezi ifakwa esimweni, esifudunyezwa ngesikhathi esifanayo sijike ama-tomahawk amabili abhekene. Ngale ndlela, amandla e-radial aphusha i-polymer ezindongeni zefomu, enze ungqimba lokujiya okufanayo olulungisa isimo se-cavity bese lupholiswa futhi ludonswe ekumeni. Ukusebenzisana okuvamile kunomjikelezo wesikhathi eside ngokusesilinganisweni nokho kuthokozela izinzuzo zokunikeza ithuba lohlelo lwento olungenamkhawulo nokuvumela izingxenye eziyinkimbinkimbi ukuba zilolongeke kusetshenziswa ihadiwe yezindleko ezincane kanye namathuluzi.
I-Thermoforming: I-Thermoforming ihlanganisa imijikelezo ehlukahlukene esetshenziselwa ukwenza izinto ezibunjwe inkomishi, isibonelo, amakhompathimenti, amabhodi, izindawo zokulala kanye neziqapha zemishini ezivela kumashidi we-thermoplastic. Ishidi le-thermoplastic elikhululekile libekwe phezu komumo futhi umoya uyathululwa phakathi kwakho kokubili, okuphoqa ishidi ukuthi livumelane nefomu lefomu. I-polymer ibe isipholile ngakho izobamba ukwakheka kwayo, isuswe efomini futhi iwebhu eyizungezile iphethwe. Okuhle kwe-thermoforming kuhlanganisa: izindleko eziphansi zamathuluzi, ithuba lokwakhiwa kwengxenye enkulu enezindawo ezincane nokuthi ngokuvamile kuwukuhlakanipha ekudalweni kwengxenye ekhawulelwe. Noma kunjalo ikhawulelwe ngokuthi izingxenye kufanele zibe ukusethwa okuqondile, kukhona isivuno esikhulu sesiqephu, kukhona izinto ezimbalwa ezingasetshenziswa nalo mjikelezo, futhi isimo sento asikwazi ukuqukatha ukuvuleka.
