Mu myaka yashize ,.uburyo bwo gutera inshinge za micro-metal (μ-MIM)yatejwe imbere hagamijwe gukora ibyuma na alloys bishobora gukoreshwa muguhingura cyane ibice bito na mikoro yubatswe. μ-MIM yongerera cyane kuboneka ibyuma hamwe nuruvange kuri micro-progaramu, nkibikoresho bishya bifite ubushyuhe buhanitse, imbaraga nubukomezi, hamwe nubushyuhe bwumuriro na magnetisme.

Byongeye kandi, ugereranije no gushushanya plastike ya micro-inshinge, uburyo bwo gukora bimetal bwakozwe na μ-MIM butuma ibikoresho bibiri byuma bitandukanye bihuzwa hamwe (bimetal co-injeniyeri) mugihe cyo gutera inshinge.

1. Ibice bibiri bigize MIM (2C-MIM)

Ubuso ni bubi kandi imbere imbere ni huzuye

Nuburyo bwo gukora ibice bimetallic, abantu bateje imbere 2C-MIM (Ibice bibiri bigize MIM). Inyungu nyamukuru yuburyo bwa 2C-MIM nuko ibikoresho bibiri bifite imitungo itandukanye bishobora guhurizwa hamwe muburyo bumwe bwo gukora, bityo bikagabanya ibikorwa byakurikiyeho (nko gusudira, kuzunguruka, guteranya, nibindi).

Ibice 2C-MIM irashobora gukora intera kuva ibice bitoboye hamwe nuburyo bwimbere bwimbere kugeza ibice byoroshye.

Intego yubushakashatsi bwose ni ugukora ibice byubwubatsi byongerewe imbaraga kubiciro byiza. Kubice byoroshye kwambara, urashobora gusa gushimangira ibice byingenzi nkibice byo guterana hamwe nibikoresho bikomeye cyangwa byinshi birwanya kwambara, nibindi bice byubatswe hamwe nibikoresho bihenze cyane.

Gukora ibice bya bimetal, gusobanukirwa gusa nuburyo bwo gutera inshinge yibikoresho byombi byo gutera inshinge ntibihagije, urufunguzo nuko ibikoresho byombi bigomba gushobora gucumurwa mu itanura rimwe no mu kirere kimwe. Kuberako igabanuka ryibice byombi ntabwo arimwe mugihe cyo gucumura, birashobora gutuma umuntu asiba cyangwa agacika. Kandi iyo icyiciro cyangiritse gishyizweho, ibintu bivanze bishobora no gukwirakwira kumupaka, bigabanya imiterere yibintu.

Igicapo 17-4PH / 316L ikomatanya icyitegererezo cyateguwe na co-inshinge

Muguhuza ibintu byo gutunganya, ubwiza bwibice 2C-MIM buba bwiza. Bitewe nubushobozi bwihariye bwo gukora igice gifite ibintu bitandukanye bidafite ibikorwa byo guterana, inzira ya 2C-MIM ntagushidikanya kwagura isoko ryimikorere ya Inganda za MIM.

Niba ingano yubunini bwa poro iri munsi ya 1um, ibikoresho byihariye byo gutera inshinge bigomba gukoreshwa muguhuza nibibazo biterwa nubuso bunini bwagushiramo ifu no gutesha agaciro.

2.Micro Metal Injection Molding Process (μ-MIM)

Microinjection ibyuma bitagira ibyuma

Ibicuruzwa na sisitemu bigenda byiyongera, bivuze ko ibice byubatswe nibikorwa muri sisitemu igoye bigenda biba bito kandi bito.

Ibi ntibisaba gusa gukoresha ibikoresho byateye imbere bifite imiterere ikwiye, ahubwo bisaba na micro-miniaturized geometrike kugirango yongere umubare wimirimo ihuriweho.

Niyo mpamvu, birakenewe gutezimbere uburyo bwiza kandi bwizewe bwo gukora ibice bito cyangwa ibice byubaka mikoro, hamwe nibice bito byakozwe na μ-MIM birashobora gukoreshwa mugusimbuza ibice bya plastike kugirango ubone ibyiza byimiterere yubukanishi, kurwanya ruswa cyangwa ubushyuhe bwinshi bwibikoresho byicyuma.

Intsinzi yiyi nzira nshya yo gukora ishingiye ku kuba inzira yayo yo guhatanira igarukira ku bikoresho bikoreshwa mu mashini cyangwa ku musaruro rusange, kandi nta kundi byagenda kuri μ-MIM.

Tekinoroji ya LIGA (ikomatanya rya lithographie na electroforming) mubisanzwe ikwiranye na 2D geometrie gusa, kandi igarukira kuri electroforming mubijyanye no gutoranya ibikoresho.

Ubundi buhanga, nk'uburyo bwo gukora mikorobe ikora amashanyarazi, gusya mikorobe no gusya mikoro, biva mu nganda zishingiye kuri silikoni zishingiye ku nganda kandi bifite ubushobozi bwo gukemura ibintu bito nka 1 mm, ariko ntibikwiye kubyara umusaruro mwinshiIbice bya 3D.

Noneho, ibice bito byakozwe na μ-MIM birashobora kuba bito nka 5 mm mubunini. Ariko, murwego rwo kunoza imikorere, nko gukomeza imiterere ukurikije ibiranga imigendekere cyangwa ibice, ibikoresho byihariye byo gutera inshinge byateguwe bishoboka rwose kuri subicron cyangwa nanometero isabwa kuri μ-MIM.

Muri rusange, kubice bya micro, MIM irashobora kwigana ibintu byikubye inshuro 10 ubunini buringaniye buringaniye, bikwiranye cyane nibice bito, niba ushaka gukora ibintu bito, ugomba gukoresha ifu nto. Noneho, ifu yicyuma iboneka ni 1μm. Ifu imwe nimwe irashobora gukora cyane kugirango itange ifu murirwo rugero rungana (urugero, Ti), mugihe izindi fu yicyuma yoroshye kubyara hamwe na parike idasanzwe ya aerosol (urugero, ibyuma bitagira umwanda).

Niba ingano yubunini bwa poro iri munsi ya 1um, ibikoresho byihariye byo gutera inshinge bigomba gukoreshwa muguhuza nibibazo biterwa nubuso bunini bwubuso bwa poro no kubora.

Shushanya microinjection ibyuma bidafite ibyuma na moteri

Kugeza ubu, μ-MIM iracyari mu cyiciro cya incubation kandi iratera imbere cyane muburyo bwa 2C-MIM. Ubwa mbere, inzira zombi zirimo gukorwa, ariko byombi birimo gukorerwa ikoranabuhanga hamwe nubushakashatsi bushoboka kubice bitandukanye bya micro-ibice cyangwa ibice byubaka.

Ubushakashatsi bwambere bwo guhatanira intego nintego ziterambere nibyingenzi munzira zabo kugirango bagere ku isoko, ariko gusa binyuze mugutezimbere ibikoresho nibikorwa byumusaruro hafi ya 2C-μ-MIM mu nganda, hamwe nubumenyi bwaba injeniyeri nabatekinisiye, birashobora kugerwaho.

Mu mezi atandatu ashize, hamwe no gukoresha ibirahuri bya ceramic na 3D muri terefone zigendanwa bigenda byitabwaho cyane, hariho kandi ibirahure byinshi bya 3D byikirahure hamwe na moderi yububiko. Ibigo byinshi kandi byinshi bifite inganda, byerekana gutera imbere kwindabyo ijana, tekinolojiya mishya, inzira nshya, ibikoresho bishya byatejwe imbere, nka: ibyuma bitagira umwanda, titanium alloy, ikariso ya MIM, igipfukisho cyinyuma ceramic, ibintu bitunganijwe nka, gutunganya ibirahuri byimyambarire, gutera inkingi uburyo bushya, gucapa no guhuza antenna; Nigute ushobora kunoza igipimo cyikirahure cya 3D, kugabanya gukoresha ingufu, no kunoza imikorere byabaye ikibazo kitoroshye ku nganda zose.
