1. Izinto zokusetshenziswa
Iyasakaza- Izinto zokusakaza ngokuvamile ziyizinto ezingezona ayoni, njengei-aluminium, i-magnesium, i-zinc, ezinamaphoyinti ancibilikayo aphansi. Ukuma komkhiqizo wokuphonsa kungaba ipuleti, ibhande, induku, njll.;
I-powder metallurgy– Insimbi noma impushana yensimbi (noma ingxube yempushana yensimbi kanye nempushana engeyona eyensimbi) njengezinto ezingavuthiwe. Nakuba zikhona ezijwayelekileizinto zensimbi eziyimpuphu, kungenzeka futhi ukuxuba izimpushana. Lokhu kuvumela ukudalwa kwezakhiwo ezithile, njengezakhiwo zikazibuthe eziphezulu zezingxenye zemoto, ezidinga izimpushana zensimbi ezincibilika phezulu. I-powder metallurgy ngokuvamile iqukethe izinto ezilandelayo:insimbi, insimbi, i-nickel, i-titanium, ithusi, i-silicon, i-phosphorus.
IZINXENYE ZE-METALLURFY YOPHUVA
2. Inqubo
Iyasakaza- ukusetshenziswa kwezinto ezisuka ku-liquid kuya ekubunjweni kwesigaba esiqinile, insimbi incibilika ngokuphelele, ukwakheka komkhiqizo wokugcina kuyashintsha.
I-Powder Metallurgy– iwubuchwepheshe benqubo yokwenza insimbi noma impushana yensimbi (noma ingxube yempushana yensimbi kanye nempushana engeyona eyensimbi) njengezinto ezingavuthiwe, ukwakhiwa nokucwiliswa, ukukhiqiza izinto zensimbi, izinhlanganisela nezinhlobo ezahlukene zemikhiqizo.
3. Ukwelashwa kokushisa
Iyasakaza- Ngokusho kwezinto ezihlukene kanye nezidingo zokusebenza kungaba nezinqubo ezahlukene zokwelashwa kokushisa, njenge-aluminium alloy annealing, ukucima, ukwelashwa kwesisombululo, ukuqinisa ukuguga;
I-powder metallurgy- indlela evamile ye-powder metallurgy, impahla ayikwazi ukuminyene ngokuphelele, iveza izikhala ngokungenakugwenywa, izonciphisa amandla ayo, ngokusho kwezidingo ezahlukene zezakhiwo ezibonakalayo, inqume ukuthi ukwelashwa kokushisa ngemva kokushisa, ngokuvamile ngokusebenzisa ukucisha nokushisa kungathuthukisa ukusebenza kwezinto.
4. Ukulawulwa kwenhlangano
Iyasakaza– Kuukufa kokusakaza, ukulawulwa kwe-microstructure kunqunywa izinga lokupholisa, elincike ezintweni ezifana nendawo engaphezulu nevolumu, futhi inhlangano yokusakaza ngokuvamile iminyene kakhulu.
I-powder metallurgy- I-Powder ngoba impahla eluhlaza incane kakhulu, ngokulawula inqubo, ingathola okusanhlamvu okufanayo, i-microstructure emihle, igweme ngokuphelele ukuhlukaniswa kokwakheka nokuhlukaniswa kwe-microstructure okukhiqizwa ukusakaza. Umjikelezo ngamunye ufaka isisindo esifanayo sempushana esikhunjeni bese uyihlanganisa ukuze ibe ukuminyana okufanayo. Izinto zokwakha ze-powder metallurgy zicindezela i-isostatic, futhi ukuminyana kwezinto ezijwayelekile ze-sintered akufani nokusakazwa.
5. Izakhiwo zemishini
Uma kuqhathaniswa nezinye izinqubo,ukufa kokusakazainikeza amakhono amahle kakhulu wokubumba. Kodwa-ke, singasebenzisa cishe amathuba afanayo okuklama njengemikhiqizo ye-powder metallurgy ukunikeza imikhiqizo izakhiwo ezingcono zemishini.
Izinto ze-Die cast azizona kazibuthe. Ngaphandle uma zisethwe ngaphakathi kwenye ingxenye eyenziwe ngenye insimbi, akukho ukufaneleka kazibuthe. I-powder metallurgy inezinhlobonhlobo zezinto kazibuthe ezitholakalayo. Enye inkinga nge-die casting ukuthi umkhiqizo untekenteke futhi uphuka kalula. Izinto eziyinhloko zezingxenye ze-die-cast yizinc ne-aluminium, okuyizinto zensimbi ezithambile.Izingxenye ze-powder metallurgy, ngokuvamile eyenziwe ngensimbi, inobunzima obuphakeme. Ukusebenzisa izinto eziqinile kungafinyelela umumo ofanayo ngezinto ezincane, ezingagcina indawo yokuklama imoto nesisindo.
6. Izindleko
Idizayini yengxenye ingumshayeli oyinhloko wezindleko, nakuba umklamo ungenziwa ngokwezifiso ukuze uvumelane nenqubo yokubumba. Kodwa-ke, kunomehluko phakathi kwemikhiqizo ye-powder metallurgy kanye ne-die casting, futhi lo mehluko ubuye ube yizici eziyinhloko ezithinta izindleko.
Ukusetshenziswa kwempahla/isivuno. Imikhiqizo ye-powder metallurgy inenani eliphansi le-scrap, okuyinzuzo enkulu ekusetshenzisweni kwezinto ezinenani eliphakeme njengethusi nensimbi engagqwali.
Ukucutshungulwa kwesibili. Izingxenye ze-Die cast zidinga ukusikwa ukuze zisuse imiphetho eluhlaza, zilungiswe kabusha futhi ziphathwe ukushisa; Izingxenye eziningi ze-powder metallurgy azidingi ukucutshungulwa kwesibili.
Ukusetshenziswa kwempahla eluhlaza. Ukuncibilika kwezinsimbi kudla amandla, ikakhulukazi ezintweni ezinamaphoyinti ancibilika aphezulu. Nakuba i-sintering iphinde idle amandla, ukusetshenziswa okuphelele kwe-sintering kungase kube ngaphansi kwalokho kokulingisa.
I-powder metallurgy kanye ne-die casting yizinqubo ezimbili ezivelele zokukhiqiza, ngayinye inezinto ezingavuthiwe ezihlukile, izinqubo, izindlela zokwelashwa kokushisa, kanye nezakhiwo zemishini. Nakuba i-die casting ngokuvamile isetshenziswa nezinsimbi ezincibilika kancane njenge-aluminium ne-zinc, i-powder metallurgy isebenzisa izimpushana zensimbi, ihlinzeka ngokwezifiso ezengeziwe ezimpahleni ezibonakalayo, njengokwenza izingxenye kazibuthe. I-powder metallurgy ihlinzeka ngokulawula okuphezulu kwe-microstructure, ukusetshenziswa okungcono kwezinto ezibonakalayo, futhi ngokuvamile kuqeda isidingo sokucutshungulwa kwesibili, okuholela ekusebenzeni kahle kwezindleko. Kodwa-ke, i-die casting ivumela amandla amahle kakhulu okubumba, nakuba kungaholela emikhiqizweni entekenteke kakhulu enezinsimbi ezithambile.
Kumaphrojekthi adinga ukunemba, amandla aphezulu, kanye nokuchithwa kwempahla encishisiwe, i-powder metallurgy inganikeza inzuzo enkulu. Kwa-JHMIM, sisebenza ngokukhethekile ezinqubweni ezithuthukisiwe ze-powder metallurgy ukuletha izingxenye zensimbi ezisezingeni eliphezulu, ezenziwe ngezifiso ezimbonini ezihlukahlukene. Cabanga ukusebenzisana nawesukuthuthukisa ukusebenza komkhiqizo wakho kanye nempumelelo yokukhiqiza.
