1. Ukubunjwa komjovo wenjoloba: Ukubumba umjovo wenjoloba kuyindlela yokukhiqiza lapho impahla yenjoloba ijovwa khona ngokuqondile kumodeli ukusuka emgqonyeni ukuze ivuthwe.Izinzuzo zokubumba umjovo wenjoloba yilezi: nakuba kuwumsebenzi wesikhashana, umjikelezo wokubumba umfushane, ukusebenza kahle kokukhiqiza kuphezulu, inqubo yokulungiselela okungenalutho ikhanseliwe, amandla okusebenza mancane, futhi izinga lomkhiqizo lihle kakhulu.
2. Ukubumba umjovo wePlastiki: Ukubumba umjovo wepulasitiki kuyindlela yemikhiqizo yepulasitiki.Ipulasitiki encibilikisiwe ijovwa ekubunjweni kwemikhiqizo yepulasitiki ngengcindezi, futhi izingxenye zepulasitiki ezifunwayo zitholakala ngokupholisa nokubunjwa.Kunemishini yokubumba yomjovo eyimishini enikezelwe ukwenza ukubumba komjovo.Ipulasitiki esetshenziswa kakhulu namuhla i-polystyrene.
3. Ukubumba nokubumba umjovo: Umumo owumphumela uvame ukuba umkhiqizo wokugcina, futhi akukho okunye ukucubungula okudingekayo ngaphambi kokufakwa noma ukusetshenziswa njengomkhiqizo wokugcina.Imininingwane eminingi, njengabaphathi, izimbambo, nemicu, ingakhiwa emsebenzini wokubumba umjovo owodwa.
Ukubumba umjovo kubuye kube isicathulo esenziwe ngomshini.Ngemuva kokuthi indawo engaphezulu iboshwe ekugcineni kwe-aluminium, ivame ukujova ngokuqondile ku-PVC, i-TPR nezinye izinto ngomshini oguqukayo ukuze wenze i-sole ngesikhathi esisodwa.Namuhla, kukhona nokubumba komjovo we-PU (igama lekhemikhali i-polyurethane) (umshini kanye nesikhunta esinobunjwa obujwayelekile bomjovo sihlukile).
Izinzuzo: Ngenxa yokuthi wenziwa ngomshini, okukhiphayo kukhulu, ngakho intengo iphansi.
Ukungalungi: Uma kunezitayela eziningi, kunzima kakhulu ukushintsha isikhunta, izicathulo zinzima ukubumba, futhi azikho izicathulo ezinamathelayo ezibandayo ezinomsebenzi omuhle kakhulu, ngakho-ke ngokuvamile kufanelekile kuma-oda anesitayela esisodwa sodwa.
Inhloso, ukusebenza kanye nomphumela wezinga lokushisa, ingcindezi, isivinini nokulawula ukupholisa
●Indlela ukulungiswa kwezilungiselelo zomshini wokubumba umjovo kuyithinta kanjani inqubo nekhwalithi
●Lungiselela izilungiselelo zokulawula isikulufu
● Ukugcwalisa izigaba eziningi nokulawula ukubamba ingcindezi yezigaba eziningi;umthelela we-crystallization, i-amorphous kanye ne-molecular/fiber orientation on inqubo kanye nekhwalithi
●Ithonya lengcindezi yangaphakathi, izinga lokupholisa kanye nokuncipha kwepulasitiki kukhwalithi yezingxenye zepulasitiki
I-Rheology yamapulasitiki: ukuthi amapulasitiki ageleza kanjani, aqondise futhi aguqule i-viscosity, i-shear kanye ne-molecular/fiber orientation
●Ubudlelwano phakathi kwesistimu yokuthela, isistimu yokupholisa, isakhiwo sesikhunta kanye nenqubo yokubumba umjovo
I-shrinkage cavity, i-shrinkage, isikhunta esingasetshenzisiwe, i-burr, i-weld line, intambo yesiliva, uphawu lwesifutho, ukuhangula, ukuwohloka kwe-warpage, ukuqhekeka / ukuphuka, ubukhulu ngenxa yokubekezelelana nokunye incazelo yenkinga yokubumba umjovo, ukuhlaziya imbangela, kanye nokwakhiwa kwesikhunta, ukubumba Izixazululo ukulawula inqubo, ukwakhiwa komkhiqizo nezinto zepulasitiki.
● Ukuhlaziywa kwembangela kanye nezinyathelo zokumelana nokushoda kweglue kanye nesikhunta esingaxutshiwe ezingxenyeni zokubumba umjovo
●Ukuhlaziya imbangela nezisombululo
●Imbangela yokuhlaziywa kanye nezinyathelo zokumelana nokushwabana kwendawo kanye nomgodi wokushwaqa (ibhamuza levacuum) lezingxenye ezibunjiwe zomjovo
