Ukwenza ngokwezifiso imikhiqizo yensimbi yokwenza ngokwezifiso
Ukufa kwe-die kuyinqubo yokusakaza yensimbi, ebonakala ngokusebenzisa umgodi wangaphakathi we-die ukusebenzisa ingcindezi ephezulu kwensimbi encibilikisiwe. Isikhunta ngokuvamile senziwe ngama-alloys amandla aphezulu, acishe afane nokubunjwa komjovo. Iningi lokufa kwabantu alinansimbi, njenge-zinc, ithusi, i-aluminium, i-magnesium, i-lead, i-tin ne-lead tin alloys kanye nama-alloys awo. Ngokuya ngohlobo lokufa kokuphonsa, kuyadingeka ukusebenzisa umshini wokubanda wokushisa noma igumbi elishisayo lokufa umshini.
Izindleko zemishini yokukhipha isikhunta ziphakeme, ngakho-ke inqubo yokufa isetshenziselwa kuphela ukukhiqizwa kwenqwaba yemikhiqizo. Kulula ukukhiqiza izingxenye zokulingisa ezifayo, ngokuvamile ezidinga izinyathelo ezine kuphela, futhi ukukhushulwa kwezindleko okukodwa kuphansi kakhulu. I-die casting ifaneleka ngokukhethekile ekukhiqizeni inani elikhulu lokuphonswa okuncane naphakathi nendawo, ngakho-ke ukukhipha i-die kusetshenziswa kakhulu ezinhlelweni ezahlukahlukene zokulingisa. Uma kuqhathaniswa namanye ubuchwepheshe ekubunjweni, ebusweni die ekubunjweni bushelelezi futhi has ephakeme ukuvumelana.
Ngokususelwa kunqubo yendabuko yokufa, izinqubo ezimbalwa ezithuthukisiwe zazalwa, kufaka phakathi inqubo yokuphonsa die porous ukunciphisa impazamo yokuphonsa nokuqeda izimbotshana. Kuyinqubo eqondile yokujova esetshenziselwa ukucubungula i-zinc, enganciphisa imfucuza futhi inyuse isivuno.
Izinsimbi ezisetshenziselwa ukusakaza oku-die ikakhulu zifaka i-zinc, ithusi, i-aluminium, i-magnesium, i-lead, i-tin ne-lead tin alloys. Yize okucindezelwe i-cast iron kungavamile, kuyenzeka futhi. Izinsimbi ezikhethekile zokufa zifaka phakathi i-Zamak, i-aluminium zinc alloy namazinga we-American Aluminium Association: aa380, aa384, aa386, aa390 ne-AZ91D magnesium. Izici zokuphonswa kwezinsimbi ezahlukahlukene zimi kanje:
I-Zinc: insimbi yokuphonsa kalula kalula. Konga kakhulu ukukhiqiza izingxenye ezincane, okulula ukugqoka, amandla aphezulu wokucindezela kanye nepulasitiki, nempilo ende yokusakaza.
I-Aluminium: isisindo esilula, ukukhiqizwa okuyinkimbinkimbi kanye nokusakazwa okubiyelwe okuncane kunokusimama okuphezulu, ukumelana nokugqwala okuqinile, izakhiwo ezinhle zomshini, ukuqhutshwa okushisayo okuphezulu nokuqhuba, namandla aphezulu ekushiseni okuphezulu.
Magnesium: kulula umshini, amandla aphezulu isisindo isilinganiso, the elula kunazo esetshenziswa die-thusi izinsimbi.
Ithusi: inokuqina okuphezulu nokumelana nokugqwala okuqinile. Phakathi kwezinsimbi ezijwayele ukusetshenziswa zokuphonsa izinsimbi, inezici ezinhle kakhulu zomshini, gqoka ukumelana namandla eduze kwensimbi.
Ukuhola nethini: ukuminyana okuphezulu, ukunemba okuphezulu, kungasetshenziswa njengezingxenye ezikhethekile zokulwa nokugqwala. Ngenxa yezizathu zempilo yomphakathi, le ngxubevange ayinakusetshenziswa njengempahla yokulungisa nokugcina ukudla. Ingxubevange yomthofu, ithini ne-antimony (kwesinye isikhathi iba nethusi elincane) ingasetshenziselwa ukwenza uhlobo lwencwajana kanye nokhonkolo ekunyathelisweni kwe-letterpress.
