Impfu ebyiri zikoreshwa mugupfa;umwe yitwa "igifuniko gipfa igice" undi "ejector apfa igice".Aho bahurira bita umurongo wo gutandukana.Igipfukisho gipfuye kirimo amasoko (kumashini ashyushye-kamera) cyangwa umwobo warashwe (kumashini ikonje-chambre), ituma ibyuma bishongeshejwe byinjira mubipfa;iyi mikorere ihuye ninshinge nozzle kumashini zishyushye cyangwa icyumba cyo kurasa mumashini ikonje.Urupapuro rusohora rurimo ibinini bisohora kandi mubisanzwe biruka, iyo ikaba ari inzira iva kumasoko cyangwa umwobo warashwe ujya mu cyuho.Igifuniko gipfuye gihagaze neza, cyangwa imbere, platine yimashini itera, mugihe uwasohoye apfa yometse kuri platine yimuka.Umuyoboro wububiko uciwemo ibice bibiri byinjizwamo, nibice bitandukanye bishobora gusimburwa muburyo bworoshye kandi bigahinduka igice cyo gupfa.

Impfu zakozwe kugirango casting irangiye izanyerera hejuru yigice cya kabiri cyurupfu kandi igume muri ejector igice nkuko abapfuye bafunguwe.Ibi byemeza ko gutoranya bizasohoka buri cyiciro kuko igice cya ejector kirimo ibinini bisohora kugirango basunike gukina muri kimwe cya kabiri.Amapine ya ejector atwarwa na plaque ya ejector, itwara neza amapine yose icyarimwe kandi n'imbaraga imwe, kugirango casting itangirika.Isahani ya pin ya ejector nayo ikuramo pin nyuma yo gusohora casting kugirango yitegure kurasa ubutaha.Hagomba kubaho pine zihagije kugirango imbaraga zose kuri buri pin zigabanuke, kuko casting iracyashyushye kandi irashobora kwangizwa nimbaraga zikabije.Amapine aracyasiga ikimenyetso, agomba rero kuba ahantu aho ibyo bimenyetso bitazabangamira intego yabakinnyi.

Ibindi bice bipfa birimo cores na slide.Cores ni ibice bisanzwe bitanga umwobo cyangwa gufungura, ariko birashobora gukoreshwa mugukora ibindi bisobanuro kimwe.Hariho ubwoko butatu bwa cores: buhamye, bwimuka, kandi burekuye.Imirongo ihamye ni iyerekejwe hamwe no gukurura icyerekezo cyo gupfa (nukuvuga icyerekezo abapfuye bafungura), kubwibyo birakosowe, cyangwa bifatanye burundu nurupfu.Ibimuka byimuka nimwe biganisha mubundi buryo ubwo aribwo bwose ugereranije no gukurura icyerekezo.Izi ngirangingo zigomba kuvanwa mu cyuho cyo gupfa nyuma yo kurasa gukomera, ariko mbere yuko apfa gufungura, hakoreshejwe uburyo butandukanye.Amashusho asa na cores yimuka, usibye gukoreshwa mugukora munsi yubutaka.Gukoresha ibice byimukanwa hamwe na slide byongera cyane ikiguzi cyurupfu.Imyanda irekuye, nanone yitwa gutoranya, ikoreshwa muguterera ibintu bigoye, nkibyobo bifatanye.Izi ngirabuzimafatizo zinjizwa mu rupfu n'intoki mbere ya buri cyiciro hanyuma zigasohoka hamwe igice kirangiye.Intangiriro noneho igomba gukurwaho n'intoki.Imyanda irekuye nubwoko buhenze cyane bwibanze, kubera imirimo yinyongera nigihe cyigihe cyigihe.Ibindi bintu bipfa harimo ibice bikonjesha amazi hamwe nu muyoboro uva kumurongo wo gutandukana.Iyi myanda isanzwe ni ngari kandi yoroheje (hafi 0,13 mm cyangwa 0.005 muri) kuburyo mugihe icyuma gishongeshejwe gitangiye kuzuza ibyuma byihuse kandi bigabanya ibisigazwa.Nta risers ikoreshwa kuko umuvuduko mwinshi utuma ibiryo bikomeza byinjira mumarembo.

Ibintu byingenzi byingenzi bipfa ni ukurwanya ubushyuhe bwumuriro no koroshya ubushyuhe bwo hejuru;ibindi bintu byingenzi birimo gukomera, gukoreshwa, kugenzura ubushyuhe, gusudira, kuboneka (cyane cyane kubipfa binini), nigiciro.Kuramba k'urupfu guterwa n'ubushyuhe bw'icyuma gishongeshejwe n'igihe cyizunguruka.Impfu zikoreshwa mugupfa gupfa zisanzwe zikozwe mubyuma bikomeye, kubera ko ibyuma bidashobora kwihanganira umuvuduko mwinshi urimo, kubwibyo bipfa bihenze cyane, bivamo amafaranga menshi yo gutangira.Ibyuma bikozwe mubushyuhe bwo hejuru bisaba gupfa bikozwe mumashanyarazi maremare.

Uburyo nyamukuru bwo gutsindwa bipfa gupfa ni kwambara cyangwa isuri.Ubundi buryo bwo kunanirwa ni kugenzura ubushyuhe n'umunaniro ukabije.Kugenzura ubushyuhe nigihe ibice byo hejuru bibaye ku rupfu kubera ihinduka ryinshi ryubushyuhe kuri buri cyiciro.Umunaniro ukabije ni igihe ibice byo hejuru bibaye ku rupfu kubera umubare munini wizunguruka.
