Kwiminyaka yakutshanje, iinkqubo yokubumba inaliti yentsimbi encinci (μ-MIM)iye yaphuhliswa ngenjongo yokuvelisa isinyithi kunye ne-alloys ezinokuthi zisetyenziselwe imveliso eninzi yamacandelo amancinci kunye ne-micro-structure surfaces. I-μ-MIM ikwandisa kakhulu ukufumaneka kweentsimbi kunye ne-alloys kwi-micro-applications, njengezinto ezintsha ezinozinzo oluphezulu lobushushu, amandla kunye nokuqina, kunye nokuhanjiswa kwe-thermal kunye nemagnetism.

Ukongeza, xa kuthelekiswa nokubumba iplastiki micro-isitofu, inkqubo yokuvelisa bimetal ephuhliswe yi μ-MIM yenza izinto ezimbini ezahlukeneyo zentsimbi ukuba zidityaniswe kunye (bimetal co-injection) ngexesha naliti yokubumba.

1. Amacandelo amabini e-MIM (2C-MIM)

Umphezulu unemingxuma kwaye umbindi wangaphakathi uxinene

Njengendlela yokuvelisa iinxalenye ze-bimetallic, abantu baye baphuhlisa inkqubo ye-2C-MIM (i-Two-Component MIM). Inzuzo ephambili yenkqubo ye-2C-MIM kukuba izinto ezimbini ezineepropati ezahlukeneyo zinokudibaniswa ngokuthe ngqo kwinkqubo yokuvelisa enye, ngaloo ndlela ukunciphisa imisebenzi edibeneyo elandelayo (njenge-welding, i-riveting, i-fastening assembly, njl.).

Amalungu anokuveliswa yi-2C-MIM ukusuka kwiindawo ezingenanto kunye nezakhiwo zangaphakathi eziyinkimbinkimbi ukuya kwizinto eziguquguqukayo ezinokuhlukana.

Injongo yalo lonke uphando kukuvelisa iinxalenye zobunjineli ezisebenzayo ngexabiso elifanelekileyo. Kumalungu alula ukunxiba, unokomeleza kuphela kwindawo amacandelo aphambili anjengendawo yokukhuhlana kunye nezixhobo ezinzima okanye ezixhathisayo zokunxiba, kunye nezinye iindawo ezakhiweyo ezinexabiso eliphantsi.

Ukwenza iinxalenye zebimetal, ukuqonda nje imilo yokubumba inaliti yezinto ezimbini zokutofa akwanelanga, eyona nto iphambili kukuba ezi zixhobo zimbini kufuneka zikwazi ukuntywila kwiziko elinye nakwimo ehlala isitofu. Ngenxa yokuba isantya sokucutheka kwezi nxalenye zimbini asifani ngexesha le-sintering, kunokukhokelela kwi-delamination okanye ukuqhekeka. Kwaye xa isigaba esiyingozi senziwe, izinto ezidibeneyo zingasasaza kunye nomda, okunciphisa iimpawu zezinto eziphathekayo.

Ngokulungelelanisa izinto zomatshini, umgangatho weengxenye ze-2C-MIM zilungiselelwe. Ngenxa yobuchule bayo obukhethekileyo bokwenza inxalenye eneempawu zemathiriyeli ezahlukeneyo ngaphandle komsebenzi wendibano, inkqubo ye-2C-MIM ngokuqinisekileyo iyakwandisa imarike yesicelo Ishishini leMIM.

Ukuba ubungakanani bamasuntswana omgubo bungaphantsi kwe-1um, izixhobo ezikhethekileyo zokutofa kufuneka zisetyenziswe ukulungelelanisa iingxaki ezibangelwa yindawo enkulu yomhlaba.ukubumba inaliti yomgubo kunye nokunciphisa amafutha.

2.Inkqubo yokuBumba iMicro Metal Isitofu (μ-MIM)

Iimveliso kunye neenkqubo ziba zincinci, oku kuthetha ukuba iinxalenye zesakhiwo kunye nokusebenza kwiinkqubo ezintsonkothileyo ziba zincinci kwaye zincinci.

Oku akufuni kuphela ukusetyenziswa kwezinto eziphambili kunye neempawu ezibonakalayo ezifanelekileyo, kodwa kunye neempawu zejometri ze-micro-miniaturized ukwenzela ukwandisa inani lemisebenzi edibeneyo.

Ngoko ke, kuyimfuneko ukuphuhlisa iindlela ezisebenzayo nezithembekileyo zokuvelisa iinxalenye ezincinci okanye i-micro-structure parts, kunye ne-micro-structure parts eveliswa nge-μ-MIM ingasetyenziselwa ukubuyisela iinxalenye zeplastiki ukuze kufumaneke iingenelo zeempawu zoomatshini, ukuxhathisa ukubola okanye ubushushu obuphezulu bezinto zentsimbi.

Impumelelo yale nkqubo yokuvelisa entsha isekelwe kwinto yokuba inkqubo yayo yokukhuphisana ilinganiselwe ngezinto eziphathekayo okanye umthamo wokuvelisa ngobuninzi, kwaye akukho ndlela yimbi kwi-μ-MIM.

I-teknoloji ye-LIGA (inhlanganisela ye-lithography kunye ne-electroforming) idla ngokufanelekileyo kuphela kwijometri ye-2D, kwaye inqunyelwe yi-electroforming ngokubhekiselele ekukhethweni kwezinto eziphathekayo.

Obunye ubuchule, obufana neendlela zokwenziwa kwe-electrochemical micro-manufacturing, micro-milling kunye ne-micro-grinding, zivela kushishino lwe-silicon-based microelectronics kwaye ziyakwazi ukusombulula iimpawu ezincinci njenge-1μm, kodwa azifanelekanga ukuveliswa kobuninziAmalungu e-3D.

Ngoku, iindawo ezincinci eziveliswe nge-μ-MIM zinokuba zincinci njenge-5μm kubungakanani besici. Nangona kunjalo, ukuze kulungiswe ukusebenza kakuhle, njengokugcina imilo ngokweempawu zokuhamba okanye iinxalenye, izixhobo ezikhethekileyo ze-injection ziye zaphuhliswa ezinokwenzeka ngokupheleleyo kwi-submicron okanye i-nanometer efunekayo kwi-μ-MIM.

Ngokubanzi, kumacandelo amancinci, i-MIM inokuphindaphinda iimpawu ezimalunga namaxesha angama-10 ubukhulu becala eliqhelekileyo, elifaneleke ngokukodwa kwiindawo ezincinci, ukuba ufuna ukudala iimpawu ezincinci, kufuneka usebenzise ipowder encinci. Ngoku, umgubo wesinyithi okhoyo ngu-1μm. Olunye umgubo lusebenza kakhulu ukuvelisa umgubo kolu luhlu lobungakanani bamasuntswana (umzekelo, iTi), ngelixa ezinye umgubo wesinyithi kulula ukuvelisa ngomphunga okhethekileyo weaerosol (umzekelo, intsimbi engatyiwa).

Ukuba ubungakanani bemilinganiselo yobungakanani bepowder bungaphantsi kwe-1um, izixhobo ezikhethekileyo zenaliti kufuneka zisetyenziswe ukulungelelanisa iingxaki ezibangelwa ngummandla omkhulu we-powder injection molding kunye ne-degreasing.

Umfanekiso we-microinjection yensimbi engenasici kunye ne-impeller

Okwangoku, i-μ-MIM isekwinqanaba lokufukamela kwaye iphuhla kakhulu ngokuhambelana nenkqubo ye-2C-MIM. Okokuqala, zombini iinkqubo ngoku zikwimveliso, kodwa zombini ziphantsi kokuqaliswa kwetekhnoloji kunye nezifundo ezinokwenzeka kwiindidi ezahlukeneyo zamacandelo amancinci okanye amacandelo amancinci.

Uphando lokuqala olukhuphisanayo kunye neenjongo zophuhliso zibaluleke kakhulu kwindlela eya kwimpumelelo yemarike, kodwa kuphela ngophuhliso lwemathiriyeli kunye neenkqubo zemveliso malunga namathuba e-2C-μ-MIM kushishino, kunye nemfundo yeenjineli kunye namagcisa, inokufezekiswa impumelelo yokwenyani.

Kwiinyanga ezintandathu ezidlulileyo, kunye nokusetyenziswa kweglasi ye-ceramic kunye ne-3D kwiifowuni eziphathwayo ukufumana ingqalelo engakumbi nangakumbi, kukho ezininzi iglasi eziphindwe kabini ze-3D kunye neemodeli zesakhiwo se-ceramic. Amashishini amaninzi analo shishini, ebonisa ukukhula kweentyatyambo ezilikhulu, ubugcisa obuthile obutsha, iinkqubo ezintsha, izinto ezintsha ziye zaphuhliswa, ezinje: insimbi engenasici, ingxubevange ye-titanium, isakhelo se-MIM, isigqubuthelo somva se-ceramic, imiba yenkqubo efana nenkqubo yokuhombisa iglasi yophuhliso lokuthungwa, inkqubo ye-inki yokutshiza entsha, ukushicilela kunye nokudibanisa kwe-antenna; Indlela yokuphucula izinga lokupasa kweglasi ye-3D, ukunciphisa ukusetyenziswa kwamandla, kunye nokuphucula ukusebenza kakuhle kuye kwaba yingxaki enzima kulo lonke ishishini.
