1. Izici zesakhiwo samabhodlela epulasitikiIsakhiwo sebhodlela lepulasitiki ngokuvamile sihlukaniswe izingxenye ezintathu: ikepisi, umzimba kanye nephansi. Isigqoko sebhodlela kanye nephansi lebhodlela kulula, futhi inqubo yokukhiqiza eyinhloko ukubumba umjovo. Umzimba webhodlela uyingxenye eyinhloko yebhodlela lepulasitiki, elinquma ukubukeka nokusebenza kwebhodlela. Izinqubo zokukhiqiza amabhodlela ikakhulukazi zifaka i-extrusion, i-blow molding kanye ne-injection molding.
Indlela ye-extrusion iwukushisa izinhlayiya zepulasitiki zibe yisimo esincibilikisiwe bese uzikhipha ngomshini wokubumba we-extrusion. Inqubo ilula futhi ikhiqiza amabhodlela ekhwalithi ephezulu. Kodwa-ke, ngenxa yezizathu ezinjengokudweba kanye nokuncipha kwemvelo emaphethelweni echweba le-extrusion, ukushuba kodonga emlonyeni nangaphansi kwebhodlela kuhluke kakhulu, okuthinta ikhwalithi yebhodlela lepulasitiki.
Indlela yokubumba iwukuvuthela izinhlayiya zepulasitiki ezishisiwe ngaphambili. Ukugeleza kwenqubo kulula, futhi ukushuba kodonga lomlomo webhodlela kanye nephansi lebhodlela ngokuvamile kufana ngokufanayo. Kodwa-ke, njengoba kokubili indawo yangaphakathi nengaphandle idinga ukucutshungulwa ngesikhathi esifanayo ngesikhathi sokubunjwa kokushaywa, ukubunjwa kwezingxenye ezinemininingwane kunzima kakhulu, futhi kunenkinga ethile yokushoda komkhiqizo.
Indlela yokubumba umjovo iwukujova ipulasitiki eshisiwe nencibilikisiwe esikhunjeni ngomshini wokubumba umjovo, bese uyipholisa esibunjeni. Inzuzo yale nqubo yukuthi ubukhulu bodonga bomlomo webhodlela nangaphansi kwebhodlela elikhiqiziwe buyiyunifomu, futhi umkhiqizo ophelile uhle kakhulu, ngakho-ke usetshenziswa kabanzi.
2. Ubuchwepheshe bokukhiqiza amabhodlela epulasitikiNgenxa yesakhiwo esiyinkimbinkimbi samabhodlela epulasitiki, inqubo ngayinye yokukhiqiza inobubanzi bayo bokufaka isicelo kanye nobunzima bokukhiqiza, ngakho-ke inqubo yokukhiqiza idinga ukuthuthukiswa nokuthuthukiswa. Isibonelo, ukusetshenziswa kwezinto ezihlanganisiwe ze-multi-layer kungathuthukisa ukumelana nokucindezela, ukumelana nezinga lokushisa kanye nokulondolozwa okusha kwamabhodlela epulasitiki; ukusetshenziswa kobuchwepheshe bokubumba obunomfutho ophansi kungathuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.
Ngaphezu kwalokho, ukuklama nokusetshenziswa komshini wokubumba umjovo nakho kuyisihluthulelo. Eminye imishini yokubumba yomjovo ethuthukisiwe ifakwe isikhunta se-swing-arm kanye nezinhlelo zokulawula ezihlakaniphile, ezingakwazi nje ukuthuthukisa ukusebenza kahle kokubumba kanye nekhwalithi yokukhiqiza, kodwa futhi kunciphise ukusetshenziswa kwamandla kwabasebenzi kanye nokuqina kwabasebenzi.
3. Ukuhlaziywa kwenqubo yesakhiwo kanye nokwenza kahle
Ukuhlanganisa izici zesakhiwo kanye nenqubo yokukhiqiza yamabhodlela epulasitiki, le ndatshana ihlaziya izinkinga zayo ezikhona kanye nezikhombisi-ndlela zokusebenzisa ngokugcwele. Isibonelo, ukusebenzisa isofthiwe yokuklama esizwa ikhompuyutha kungaklama isakhiwo sebhodlela esinembe kakhudlwana futhi esilungiselelwe futhi kunciphise izindleko zokukhiqiza nokumosha; ukwenza kahle inqubo yokusebenza yomshini wokubumba umjovo kungasheshisa ukushintshwa kwesikhunta nesikhathi sokuhlanganisa, futhi kuthuthukise imiphumela yokubumba kanye nekhwalithi.
Ngaphezu kwalokho, isikhunta esingase sisetshenziswe kabusha singasetshenziswa futhi inhlangano eqinile yokuhlola ikhwalithi ingasungulwa ukuze ihlole ikhwalithi nokuqapha amabhodlela ngesikhathi senqubo yokukhiqiza ukuze kuqinisekiswe ukuhambisana nokuqina komkhiqizo.
4. IsifinyezoUkufingqa, ubuciko besakhiwo samabhodlela epulasitiki buyisici esibalulekile esithinta ikhwalithi yawo nokusebenza kahle kokukhiqiza. Ngokubuka izinkinga zayo ezikhona kanye nezikhombisi-ndlela zokuthuthukisa, amasu ahlukene nobuchwepheshe bungasetshenziswa ukuthuthukisa ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza.
