Ziziphi iindidi eziphambili zokubumba

Ukongeza, abavelisi bomngundo banokwahlulwa babe ziimolds zehardware ngokwezinto ezahlukeneyo zokubumba umngundo: kubandakanya ukunyathela kufa, ukufogina kuyafa, ukubulawa kwe-extrusion, ukufa kwe-extrusion, ukuphosa ukufa, ukubunjwa kuyafa, njl. ii-non-metallic dies zahlulwe zibe: yi-plastic molds kunye ne-Inorganic non-metal molds. Ngokwezinto ezahlukeneyo zokubumba ngokwazo, isikhunta sinokuhlulwa sibe: i-sand mold, i-metal mold, i-vacuum mold, i-parafini mold kunye nokunye. Phakathi kwabo, kunye nokuphuhliswa ngokukhawuleza kweeplastiki ze-polymer, iimbumba zeplastiki zihlobene ngokusondeleyo nobomi babantu. Iimbumba zeplastiki zinokwahlulwa ngokubanzi zibe: iimbumba zokubumba iinaliti, i-extrusion molds, i-gas-assisted molds, njalo njalo.
