Ni ibihe bice by'ibumba bigizwe na:

Uretse ibumba ubwaryo, rikenera kandi ishingiro ry'ibumba, ishingiro ry'ibumba, n'ishingiro ry'ibumba kugira ngo igice gisohoke. Ibi bice muri rusange bikozwe mu bwoko bwa 'universal type'.

Ifumbire:

1. Ibikoresho bitandukanye bikoreshwa mu nganda kugira ngo haboneke umusaruro ukenewe hakoreshejwe uburyo nko gushushanya mu nganda, gushushanya mu buryo bwa "blow molding", "extrusion", "die-casting" cyangwa "forging molding", "smelting", "folding", "smelling", "stampering". Muri make, "mold" ni igikoresho gikoreshwa mu gukora ibintu bikozwe. Iki gikoresho kigizwe n'ibice bitandukanye, kandi "molds" zitandukanye zigizwe n'ibice bitandukanye. Gitunganya ahanini imiterere y'ikintu binyuze mu guhindura imiterere y'ikintu cyakozwe. Kizwi nka "Mama w'Inganda".

2. Mu bikorwa by'imbaraga zo hanze, ahantu hadakoreshejwe ikintu hahinduka igikoresho gifite imiterere n'ingano runaka. Gikoreshwa cyane mu gukubita, gucura, gufata ibintu bikonje, gusohora, gukanda ibice by'icyuma bikozwe mu ifu, gukanda igitutu, no gukora no gutunganya pulasitiki z'ubuhanga, kawunga, ibumba n'ibindi bicuruzwa hakoreshejwe gukanda cyangwa gushushanya. Aho hantu hafite imiterere yihariye cyangwa imiterere y'imbere, kandi imiterere y'aho hantu ifite inkombe irashobora gukoreshwa mu gutandukanya ahantu hadakoreshejwe ikintu hakurikijwe imiterere y'aho hantu (gukubita). Imiterere y'aho hantu imbere ishobora gukoreshwa kugira ngo haboneke imiterere y'ibice bitatu by'aho hantu. Aho hantu muri rusange harimo ibice bibiri: aho hantu hashobora kwimurwa n'aho hantu hadakoreshejwe ikintu (cyangwa aho hantu hanini n'aho hantu hanini), bishobora gutandukanywa cyangwa guhuzwa. Ibice bikurwamo iyo bitandukanyijwe, kandi aho hantu hashyirwa mu mwanya w'aho hantu kugira ngo hakorwe iyo hafunze. Aho hantu ni igikoresho gifite imiterere igoye kandi gishobora kwihanganira imbaraga zo kwaguka kw'aho hantu. Gifite ibisabwa cyane kugira ngo habeho imbaraga, gukomera, gukomera kw'ubuso, ubukana bw'ubuso no gutunganya neza. Urugendo rw'iterambere ry'ibihumyo ni kimwe mu bimenyetso by'ingenzi by'urwego rw'inganda zikora imashini.

【Gushyira mu byiciro ibumba】

Dukurikije ibikoresho bitandukanye byo gushushanya: ibumba ry'ibikoresho, ibumba rya pulasitiki, n'ibumba ryabyo ryihariye.

1. Ibikoresho by'ibikoresho bigabanyijemo: harimo ibikoresho byo gusiga (nk'ibikoresho bifunga, ibikoresho bifunga, ibikoresho bikurura cyane, ibikoresho bihindura, ibikoresho bigabanya ubushyuhe, ibikoresho bifunga, ibikoresho bikura, ibikoresho bya pulasitiki, nibindi), ibikoresho byo gushushanya (nk'ibikoresho byo gushushanya), ibikoresho bihagarika ubushyuhe, nibindi), ibikoresho byo gusohora ubushyuhe, ibikoresho byo gusohora ubushyuhe, ibikoresho byo gutwika ubushyuhe, nibindi;

2. Ibikoresho bitari iby'icyuma bigabanyijemo: ibikoresho bya pulasitiki n'ibikoresho bidakomoka ku byuma. Dukurikije ibikoresho bitandukanye by'ibikoresho ubwabyo, ibikoresho bishobora kugabanywamo: ibikoresho by'umucanga, ibikoresho by'icyuma, ibikoresho by'ingufu, ibikoresho bya parafini n'ibindi. Muri byo, hamwe n'iterambere ryihuse rya pulasitiki ya polymer, ibikoresho bya pulasitiki bifitanye isano rya hafi n'ubuzima bw'abantu. Ibikoresho bya pulasitiki muri rusange bishobora kugabanywamo: ibikoresho byo gushushanya inshinge, ibikoresho byo gushushanya byoherezwa hanze, ibikoresho byo gushushanya bifashishwa na gaze, n'ibindi.
