Inqubo ye-MIM nezinto zokusebenza

Kusukela ekuhlaziyeni inqubo essence ofinqubo yokubumba umjovo wensimbi, okwamanje kuyinqubo efaneleke kakhulu yokukhiqiza ngobuningi bezinto ezincibilikayo eziphezulu, amandla aphezulu kanye nezingxenye zomumo eziyinkimbinkimbi. Izinzuzo zayo zingafingqwa ngale ndlela elandelayo:

• (1) Ukukhiqiza kwe-MIMingakha izingxenye ezihlukahlukene zensimbi ezinezimo eziyinkimbinkimbi ezinezinhlangothi ezintathu (inqobo nje uma le nto ingenziwa ibe yimpushana ecolekileyo). Ukuminyana nokusebenza kwengxenye ngayinye yengxenye kuyavumelana, okungukuthi, isotropic. Ihlinzeka ngezinga elikhulu lenkululeko yokuklama ingxenye.

• (2) Ukubumba komjovo we-MIM kungakhuphula ukukhiqizwa kwezingxenye eduze komumo wokugcina, ngokunemba okuphezulu kobukhulu.

• (3) Ngisho nasekufakweni kwesigaba esiqinile, ukuminyana okuhlobene kwemikhiqizo yokubumba umjovo wensimbi kungafinyelela ngaphezu kwama-95%, futhi ukusebenza kwayo kuqhathaniswa nalokho kokubumba izinto zokwakha. Ikakhulukazi ukusebenza okuguquguqukayo kuhle kakhulu.

• (4) Inani lei-powder metallurgy(PM) umshini wokubumba othomathikhi uphakeme izikhathi eziningana kunomshini wokubumba umjovo. Izinsizakalo zokubumba umjovo wensimbi zingasebenzisa kalula isikhunta se-multi-cavity esisebenza kahle kakhulu, impilo ende yesevisi yesikhunta, nokushintshwa okulula nokusheshayo nokulungiswa kwesikhunta.

• (5) Izinto zomjovo zingasetshenziswa ngokuphindaphindiwe, futhi izinga lokusebenzisa impahla lingaphezu kwama-98%.

• (6) Umkhiqizo uphenduka ngokushesha. Ukuguquguquka okuphezulu kokukhiqiza kanye nesikhathi esifushane kusuka ekwakhiweni kuya ekukhiqizweni kwemikhiqizo emisha.

• (7) Umjovo wensimbi we-MIM ufaneleka ngokukhethekile ukukhiqizwa ngobuningi futhi unokungaguquguquki kokusebenza komkhiqizo. Uma izingxenye ezikhiqizwayo zikhethwe kahle futhi inani likhulu, izinzuzo eziphezulu zezomnotho zingatholakala.

• (8) I-MIM inohlu olubanzi lwezinto kanye nezinkambu ezibanzi zokusebenzisa. Izinto ezingase zisetshenziselwe ukubumba umjovo zibanzi kakhulu, njengensimbi ye-carbon, i-alloy steel, insimbi yamathuluzi, i-refractory alloy, i-carbide enosimende, i-alloy gravity alloy, njll.

Idivayisi ye-MIM

Ngokusho kwenqubo yokubumba umjovo wensimbi, imishini ehilelekile ku-MIM ihlanganisa umshini ohlanganisiwe wokuxuba kanye ne-granulating, umshini okhethekile wokubumba umjovo we-Metal injection molding, isithando somlilo esishisayo, isithando somlilo, kanye nemishini ehlukahlukene yokuhlola kanye nesesibili.
