Ukufakwa kweplastiki ekubumbeni kuqheleke kakhulu kwishishini lokulungisa ngemilomo. Okokuqala, ixabiso eliphantsi kwaye ixabiso eliphantsi lenza ukuba olu hlobo lwemilomo luthandwe ngakumbi. Okwesibini kukuhambelana kwemveliso. Xa kuthelekiswa machining ngemilomo eyi – metal, Inaliti yokubumba umlomoUkufana okuphezulu, oku kungenxa yenkqubo yokulungisa isinyithi, naziphi na iingozi ezincinci kunokubangela ukuba ukusebenza kombhobho kutshintshe (njengokunxiba isixhobo xa ujika, ukungapholi ngokwaneleyo, njl. ihlolwe rhoqo ukuqinisekisa ukuba ukusebenza kwemveliso kuzinzile). Inaliti yokubumba ayinazo iimfuno eziphakamileyo ezinjalo. Logama nje ukungunda unengqibelelo, uxinzelelo kunye nobushushu ziyahambelana, kwaye ixesha lokupholisa liyahambelana, ukusebenza kwemveliso eyenziweyo kuyalingana kwaye kuzinzile kakhulu.

Enye inzuzo yeplastiki Inaliti yokubumba umlomos yeyokuba kwimilomo yemilomo enemilo entsonkothileyo, ukushenxiswa kwesinyithi kuhlala kufuna iindleko zokuvelisa eziphezulu, ngelixa iiplastikhi zokubumba zeplastiki zingenayo le ngxaki. Ixabiso lokungunda liphezulu, kodwa lisasazeka ngokulinganayo kuye ngamnye Xa kusenziwa imibhobho yemilomo, ixabiso liya kuba sezantsi kakhulu, nelimisela ukuba xa kusenziwa imveliso enkulu, le ndlela inokunciphisa iindleko zokuvelisa. Kuba mveliso amancinci-ibhetshi, processing ngomatshini kufanelekile ngakumbi.
