Xa abantu besiva 'i-micro metal injection molding', okanye iMIM kwisikali esincinci, ingcinga ekhawulezileyo isoloko imalunga neendawo ezincinci, ezintsonkothileyo. Yinyani leyo, kodwa kukwalapho kuhleli khona ukungaqondi kakuhle kokuqala. Asikokwenza nje izinto zibe zincinci; imalunga nokwenza izinto ezincinci ezisebenza ngokwenene kwihlabathi lokwenyani, ngokungaguqukiyo, kwaye ngaphandle kokwaphula ibhanki. Umsantsa phakathi kweprototype oww kwi-microscope isilayidi kunye nokuveliswa kwemveliso yeziqwenga ze-500,000 ezisinda kwindibano kunye nomsebenzi apho ibali lokwenyani likhona. Ndibone iiprojekthi ezininzi kakhulu zikhubeka ngokuyiphatha njengoguqulelo olusezantsi lwe-MIM eqhelekileyo. Ifiziksi, indlela yokuziphatha kwezinto eziphathekayo, indlela yokucinga yezixhobo—zonke ziyatshintsha.
Umdaniso weMaterial kwi-Micro Scale
Ukusebenza nge-feedstocks ye-MIM encinci ngumdlalo webhola owahlukileyo. Ujongene nomgubo ocolekileyo, rhoqo ungaphantsi kwe-10 microns, kwaye inkqubo yokubopha iba yinto ebalulekileyo. Akunjalo nje ngokubamba umgubo kunye; imalunga nendlela equkuqela ngayo kumasango kunye neembaleki ezinokuba yi-0.15mm kuphela ububanzi. Sake saba neprojekthi yecandelo lesixhobo sotyando sisebenzisa i-316L yensimbi engenasici. Isondlo esisemgangathweni asizukuzalisa icandelo elinodonga olucekethekileyo ngokuthembekileyo. Kwafuneka sisebenze ngokusondeleyo kunye nomthengisi wezinto eziphathekayo ukuze sidibanise i-rheology-engaphezulu ye-wax-polymer binder adjustment-ukufumana loo nto iqhubekayo, ukuhamba kwe-laminar. Luhlobo lwezandla-kwizinto eziphathekayo ezahlula iiprojekthi eziphumeleleyo kwezo zingaphumelelanga.
Ukubophelela kunye ne-sintering iba zizenzo zocingo oluphezulu. Ngamacandelo amancinci anjalo, umngcipheko wokuphazamiseka okanye ukuhla ngexesha lokujikeleza kwe-thermal mkhulu. Iiprofayili zeqondo lokushisa kwisithando somlilo kufuneka zichaneke ngendlela emangalisayo. Ndikhumbula ibhetshi yezibiyeli ze-cobalt-chrome orthodontic apho sabona i-ovalization encinci kwimingxunya enyukayo emva kokuntywila. Umoni? Ubunzima be-thermal obungalinganiyo kwinxalenye yoyilo kwi-tray ye-sintering idala i-micro-yantlukwano ekutyhilekeni kobushushu. Kusinyanzele ukuba sihlengahlengise izixhobo zetreyi, hayi inxalenye. Zezi nkcukacha zenkqubo yesibini edla iiyure zobunjineli.
Apha kulapho amava anealloyi ezikhethekileyo, njengale nto uyibonayo kwiprosesa yexesha elide njenge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), iba yinto efanelekileyo. Bebekwi-casting kunye ne-machine amashumi eminyaka. Olo lwazi olunzulu lwezinto eziphathekayo-indlela i-nickel-based based or cobalt-based alloys eziphatha ngayo phantsi kobushushu kunye noxinzelelo-iguqulela ngokumangalisayo xa uhamba kwi-MIM encinci kunye naloo alloys afanayo. Ayilodluliselo oluthe ngqo, kodwa elo thuku le-metallurgical lixabiseke kakhulu. Ungajonga indlela yabo yokuthembeka kwezinto kwindawo yabo, https://www.tsingtaocnc.com. Kwiinxalenye ezincinci, ukuqala kumthengisi ofumana isiseko sesayensi yezixhobo sisiqingatha sedabi.
Isixhobo: Apho Ukuchaneka Kudibana nePragmatism
Umngundo yinto yonke. Ngamacandelwana amancinci, uhlala usebenzisa izixhobo eziqinileyo okanye i-tungsten carbide efakwe. Ipolishi, uyilo lokungenisa umoya, iziteshi zokupholisa-zonke zenziwe kwisikali esifuna i-EDM kunye ne-ultra-precision milling. Kodwa nantsi intloko esebenzayo: ukugcinwa. Intwana yothuli, intwana encinci ye-carbonized binder buildup kwi-micro-cavity, kwaye isivuno sakho siyehla. Siphumeze irejimeni yokucoca i-ultrasonic ye-high-frequency yezixhobo phakathi kwee-run, ezivakala zicacile, kodwa ukufumana i-frequency echanekileyo kunye nesisombululo esicocayo ngaphandle kokugungqa indawo epholileyo yayiyinkqubo yokulinga kunye nephutha.
Esinye isifundo esifundwe kabuhlungu: musa ukwenza nzima kakhulu isixhobo ngenxa yaso. Kwangoko, siye sayila i-multi-cavity mold enemingxuma engama-64 yegiya encinci. Umbono yayikukunyusa imveliso. Kodwa ukuzalisa ukungaguquguquki kuyo yonke imingxunya yayiliphupha elibi; utshintsho oluncinci kubude bembaleki lube lukhulu. Sibuyele kuyilo lwe-16-cavity kunye nenkqubo yembaleki elinganayo, elinganayo. Isiphumo sesixhobo ngasinye besisezantsi, kodwa isivuno kunye nokungaguquguquki kwenxalenye kunyuke, okwenza uqoqosho luphela lubengcono. Ngamanye amaxesha, kwi-MIM encinci, ngaphantsi kungaphezulu.
Ukukhupha umoya kobunye ubugcisa obuchuliweyo. Ngomthamo omncinci womoya oza kushenxiswa, ukuphuma komoya okungonelanga akusoloko kubangela izithonga ezicacileyo ezimfutshane. Inokubangela ukutshiswa okuncinci kwe-binder (ukudala iziphene ezibonakalayo kuphela emva kokucwiliswa) okanye iimpawu ezincinci zokungabaza ezichaphazela ukugqitywa komphezulu. Saqalisa ukusebenzisa iintsimbi ezinentunja ukuze kungene umoya kwiindawo ezibalulekileyo, nto leyo eyayitshintsha-tshintsha iindawo ezineembambo ezibhityileyo.
Ibhulorho ukuya kwiMisebenzi yeSekondari
Kunqabile ukuba inxalenye yeMIM encinci iphume kwisikhitshane esishushu esilungele ukuthunyelwa ngenqanawa. Phantse rhoqo, kukho umsebenzi wesibini. Le yingongoma ephambili edla ngokujongelwa phantsi kucwangciso lweprojekthi. Inkampani efana QSY, kunye nokuhlanganiswa kwayo CNC Machining ukukwazi, kunenzuzo eyahlukileyo apha. Yiba nomfanekiso-ngqondweni wenxalenye ye-MIM encinci efuna ibhore ebaluleke kakhulu ukuba inyamezeleke +/- 0.005mm, okanye ubuso obufuna ukugqitywa komphezulu ocolekileyo kakhulu. Inkqubo ye-sintering iyodwa ayiyi kuphumeza loo nto.
Sasinecandelo lesixhobo soluvo esincinci apho indawo edibeneyo idinga i-flatness spec engaphaya kwamandla enkqubo. Ukuzama ukuyiphumeza ngokwenza sintering kuphela kukhokelele kumaxabiso amakhulu enkunkuma. Isisombululo yayikukuyila inxalenye yeMIM kunye nesibonelelo somatshini esincinci kobo buso kwaye emva koko usebenzise inkqubo echanekileyo yokugaya i-post-sintering. Ukuba nobuchule bomatshini ngaphakathi kwindlu, njengoko i-QSY isenza, ilungelelanisa le ncoko. I-MIM kunye namaqela omatshini anokusebenzisana ukusuka kwinqanaba loyilo, ethatha isigqibo sokuba zeziphi iimpawu emaziqulunqwe nge-MIM kwaye zeziphi zigqitywe ngomatshini, ukulungiselela iindleko kunye nokuchaneka.
Le ntsebenziswano ibalulekile. Ithintela ukukhombana ngeminwe okwenzekayo xa iMIM isenziwa kwivenkile enye kunye nomatshini ochanekileyo kwenye. Inxalenye yakho igqwethiwe ngexesha le-sintering, ngoko ke asinakukwazi ukubamba ukunyamezela. Hayi, isixhobo sakho soomatshini sisebenzisa uxinzelelo oluninzi. Umthengisi odibeneyo unqumla loo ngxolo. Kwixabiso eliphezulu, amacandelo amancinci achanekileyo, olu lawulo lokuphela kokuphela aluyinto enqabileyo; yimfuneko.
Iintsilelo zokwenyani zeHlabathi kunye neePivots
Ayingawo onke amabali ayimpumelelo, kwaye lawo ngawona ufunda kuwo amaninzi. Sakhe sacaphula kwiprojekthi ye-micro-latch mechanism kwi-17-4PH engenasici. Le ndawo yayineendonga ezinqamlezileyo ezinqamlezileyo kunye nencinci, eethe-ethe yehenjisi ephilayo. Sasizithembile. Sifumene iprototype evunyiweyo, kodwa kwimveliso yokulinga, indawo yehinge ibonise ubuqhophololo obuphakathi. Oyena nobangela? Landela umkhondo we-oksijini ngexesha lokuntywila, ebethelele loo jiyometri ibhityileyo. Umgangatho we-sintering ubungacocekanga ngokwaneleyo kolu phawu kweso sikali.
Ukulungiswa kwakubiza kakhulu: ukuya kwisithando somlilo kunye noxinzelelo oluyinxenye lwe-hydrogen ecocwe kakhulu yelo nyathelo lithile lokutshisa. Yabulala umda weprojekthi, kodwa yagcina inxalenye. Ngoku, kulo naluphi na uyilo olune-ultra-thin, iimpawu ezithwele umthwalo, senza uhlalutyo oluqatha ngakumbi lomoya we-sintering kunye nokusebenzisana kwayo kunye nekhemistri yealloy ethile. Yindawo yokukhangela eye yongezwa kuluhlu lwethu lwe-DFM (uYilo lokuVeliswa) ngenxa yokusilela.
Olunye ukusilela yayikukusebenzisa kakubi ngokwenene. Umxhasi wayefuna i-MIM encinci ye-pin elula, encinci. Yayiyimilo esisiseko ye-cylindrical. Senze njalo, kodwa kwi-post-mortem, kwacaca ukuba ukujika okuncinci okanye ukugaya ngokuchanekileyo bekuya kuba neendleko eziphezulu kwijometri. Amandla kaMicro MIM anzima, hayi ubungakanani nje. Sifunde ukutyhala ngasemva ngakumbi, ukukhokela abathengi kwinkqubo elungileyo, nokuba oko kuthetha ukulahlekelwa sisicaphulo. Yakha ukuthembeka kwexesha elide.
Ukukhangela Phambili: Ingqondo yokuHlanganisa
Ibhekisa phi yonke le nto? Ikamva, ndicinga ukuba, lilele kwinkqubo enzulu yokudibanisa kunye noyilo olukrelekrele. Sibona umdla ongakumbi wokudibanisa i-MIM encinci kunye nezinye iindlela zokwenza izinto ezincinci okanye indibano yokubumba. Kodwa isiseko sihlala sisixhobo kunye nenkqubo yokulawula. Kumalunga nokuba nomfanekiso opheleleyo, ukusuka kumgubo ukuya kugqitywa, inxalenye edibeneyo.
Kungenxa yoko le nto imodeli yomenzi odibeneyo othe nkqo unyanzelekile. Inkampani eqondayo utyalo mali kwaye iqokobhe ngundo ukuphosa iindawo ezinkulu, ezintsonkothileyo zizisa ukuqonda okupheleleyo kokuhamba kwesinyithi kunye nokuqiniswa kwetafile. Xa zikwasebenza kwi-MIM encinci kunye nokuchaneka CNC Machining, njengemisebenzi echazwe yi-QSY, banokucebisa ngokungakhethiyo eyona nkqubo ilungileyo yecandelo elinikiweyo. Ngaba le nxalenye ifanelekele ngcono utyalo-mali oluncinci okanye iMIM encinci? Ukuba nezakhono zozibini phantsi kophahla olunye kuthetha ukuba impendulo iqhutywa kukufaneleka kobugcisa, hayi ngenkqubo enye enikezelwa yivenkile ethile.
Nabani na ontywila ekubumbeni inaliti yentsimbi encinci, ingcebiso yam engacelwanga yile: jonga ngaphaya komatshini kunye nokungunda. Jonga kuyo yonke i-ecosystem-inkxaso yesayensi yezinto, isakhono sesibini sokusebenza, kwaye okona kubaluleke kakhulu, imbali yokusombulula iingxaki yeqela osebenza nalo.
