Izinsimbi ezingagqwali, ama-alloys, nezitsha zobumba ziphakathi kwezinto ezikuphothifoliyo ye-MIM Molding leyoI-Titanium Metal Injection Molding(TiMIM) iyakwazi ukubumba.

Ukuze kwakhiwe isitoko esingasetshenzwa ngemishini yokubumba umjovo, i-TiMIM ihlanganisa ukuhlanganisa insimbi eyimpuphu ye-Titanium nento ehlanganisayo. Ngokuphambene nezivamileIzingxenye zensimbi ezenziwe ngomshini we-Titanium, ukubumba umjovo wensimbi kwenza kube nzimaIzingxenye ze-Titaniumukuze ibunjwe ngokunembile ekusebenzeni okukodwa futhi ngevolumu ephezulu.

Ama-undercuts nogqinsi oluhlukahlukene olufika ku-0.125′′ noma u-3mm yizici ezingatholakala ezingxenyeni ze-TiMIM. Ukwengeza, izingxenye ze-TiMIM zingaqedwa ngomshini uma kudingeka futhi zithathe izindlela zokwelapha ezingaphezulu, ezifana ne-anodizing kanye ne-electropolishing.

 Izingxenye Zokubumba Umjovo Wensimbi Ye-Titanium Ezenziwe I-JHMIM

I-Titanium alloy iyinsimbi ebalulekile eyakhiwe phakathi nekhulu lama-20, ngenxa yayoukuminyana okuphansi,amandla athile aphezulu,ukumelana nokugqwala okuhle,ukumelana nokushisa okuphezulu,akukho magnetic,ukusebenza kahle kwe-weldingkanye nezinye izakhiwo ezinhle kakhulu, ezisetshenziswa kabanzi ku-aerospace, izimoto, i-bioengineering (ukuhambisana okuhle), amawashi, izimpahla zezemidlalo, ukuvikelwa kwemvelo kanye neminye imikhakha, kodwa ukusebenza kwemishini ye-titanium ne-titanium alloy kumpofu, Izindleko eziphezulu zokukhiqiza zikhawulela ukusetshenziswa kwayo kwezimboni, ikakhulukazi eziyinkimbinkimbi. izingxenye.

I-Powder Injection MoldingUbuchwepheshe be-PIM ubuchwepheshe obuthuthukayo obushesha kakhulu ku-powder metallurgy, futhi buthathwa njengobuchwepheshe obushisa kakhulu bokulungiselela ingxenye. Ubuchwepheshe inhlanganisela bendabuko powder metallurgy ukwakha ubuchwepheshe kanye plastic umjovo ukubumba ubuchwepheshe, hhayi kuphela kunezinzuzo ezivamile powder metallurgy inqubo inqubo kancane, akukho ukusika noma ukusika kancane, izinzuzo zezomnotho okusezingeni eliphezulu, futhi banqobe bendabuko powder metallurgy inqubo impahla ephansi. ukuminyana, izinto ezingalingani, izakhiwo eziphansi zemishini, akulula ukwenza udonga oluncane, izingxenye ze-mim zesakhiwo eziyinkimbinkimbi.

Kuyasiza ikakhulukazi ekulungiseleleni imikhiqizo yokwakha eseduze-ehlanzekile enejometri eyinkimbinkimbi, isakhiwo esifanayo nokusebenza okuphezulu. I-geometry, izakhiwo zemishini kanye nokunemba komkhiqizo wenqubo yokubumba umjovo we-titanium alloy powder ingafinyelelwa engenakutholwa ngenqubo yendabuko. Kodwa-ke, insimbi ye-titanium inomsebenzi ophezulu futhi kulula ukusabela nge-carbon, umoya-mpilo ne-nitrogen ukukhiqiza i-TiC, i-TiO2, i-TiN nezinye izinhlanganisela, okwenza kube nzima ukuthuthukisa ukuminyana kwe-sintering kanye nezakhiwo zemishini.

Ngokuvamile, izingxenye ze-lim ungatholi ukwelashwa ngemuva kokwelashwa, futhi i-sintering ivame ukusetshenziswa njengenqubo yokugcinaInqubo ye-MIM, onomphumela wokuhlanganisa kanye nezakhiwo zamakhemikhali ezifanayo zezakhi ze-alloying. Ngokwesibonelo, lapho u-Obasi eculaAmasampula e-Ti-6AI-4V, izinga lokushisa le-sintering lalingu-1520-1680 degrees Celsius.

Umshini wokubumba we-titanium we-JHMIM

Njengamanje, ukubumba komjovo we-titanium alloy kusetshenziswa kabanzi ku-aerospace, umkhumbi wezempi, izimoto, amakhemikhali kanye ne-petrochemical fields, kanye nokubumba komjovo we-titanium alloy kunamathemba abanzi okusebenza. I-United States yamukele inani elikhulu lezingxenye zesakhiwo se-titanium alloy emkhakheni we-aerospace.

Isibonelo, ingxubevange ye-titanium esetshenziswe ku-F-22, indiza yokulwa yesizukulwane sesine yase-United States, yenza u-38.8% wesakhiwo sendiza; ukusetshenziswa kwe-titanium kwe-Rah-66, isibhamu, yi-12.7%; Ukusetshenziswa kwe-titanium kwe-TF31, i-aeroengine, kanye nokusetshenziswa kwe-titanium ye-Apollo spacecraft kufinyelela ku-1180KG. Mayelana namandla, i-titanium alloy izosetshenziswa kabanzi embonini yomphakathi, ikakhulukazi izingxenye zezimoto, izingxenye zemishini yezokwelapha, izingxenye ze-graft ye-biological.

I-Titanium alloy isetshenziswa kuma-valve enjini, izinduku zokuxhuma, ama-crankshafts neziphethu, ezingakwazi ukunciphisa isisindo semoto kuphela, zandise impilo yemoto, kodwa futhi zithuthukise isivinini. Emkhakheni womphakathi, intengo ye-titanium alloy kufanele ibe yinto yokuqala yokucatshangelwa, izindleko zokukhiqiza, ukusebenza okuphezulu komjovo we-titanium alloy izingxenye zendlela yilezi:

1. Ingxubevange yokufunda ye-titanium ifanele izidingo ezikhethekile ze-TiMIM
2. Thuthukisa ubuchwepheshe obusha bokukhiqiza impushana obushibhile bezinto zokusetshenziswa ze-Ti-MIM
3. Lungiselela amapharamitha wenqubo ye-Ti-MIM ukuze ulawule ikhwalithi yomkhiqizo
4. Yakha uhlelo olusha oluhlekisayo lwe-Ti-MIM lokubopha
5. Thuthukisa izindinganiso ze-Ti-MIM zezimoto, imikhumbi nezinye izinkambu, futhi ukhuthaze ukusetshenziswa okukhulu kwe-titanium ne-titanium alloy alloy injection molding

Imishini yesimanje yokubumba kagesi, i-batch debind ne-sintering furnaces yesimanje, ama-solvent debinding systems, 5-axisCNC imishinikanye nezindawo zokugaya, iziklo ze-ceramic, i-coining, i-laser etching/eqoshiwe, namalebhu okuhlola konke kusetshenziswa inkampani ye-JH MIM.

Uhla oluphelele lwezinsizakalo ezingeziwe zinikezwa yiJH MIM, okufaka i-prototyping esheshayo, i-plating, i-laser welding, ukwelashwa kokushisa, ukuqedwa kwendawo nokupholishwa, ukuhlanganisa, ukuphuma kwephakethe lokugcina, nokuningi. Njengengxenye yamanani ayinhloko e-JH MIM, idizayini yosizo lwekhono lomkhiqizi inikezwa ngaphandle kwenkokhiso. Ibhizinisi lengamele ukuklanywa nokwakhiwa kwe-single kanye ne-multi-cavity, i-hot runner, kanye nesikhunta esikhululayo ezitolo zamathuluzi zasekhaya eziseduze.
