Xa abathengi bebuza 'ngexabiso lokubumba inaliti yentsimbi', badla ngokuthemba inani elilula lenxalenye nganye. Leyo yimbono yokuqala ephosakeleyo. Ixabiso asiloxabiso lesincamathelisi; yincoko eqala ngemodeli yeCAD ize iphele ngengxelo yokugqibela yohlolo. Kumalunga nexabiso lilonke lobunini becandelo elisebenzayo, hayi nje umyalelo wokuthenga. Ndibone iiprojekthi ezininzi ziphazamisekile ngenxa yokuba isicatshulwa sokuqala sasibukeka kakuhle, kodwa iindleko ezifihliweyo zemisebenzi yesibini, imiba yomgangatho, kunye nokulibaziseka kwexesha elikhokelayo azizange zifakwe kuyo.
Iqala ngeFeedstock kunye neJiyometri
Ixabiso lempahla ekrwada ye-MIM feedstock-loo ntsimbi engumgubo ixutywe ne-binder-litikiti nje lokungena. Kodwa ukhetho lwe-alloy ngokukhawuleza lwahlula indlela. Uya kumgangatho we-17-4PH ongenasici? Kuyaqikelelwa ngokufanelekileyo. Kodwa xa isicelo sibiza i-nickel-based okanye i-cobalt-based alloy Ukumelana nobushushu obuphezulu, njengakumanye amacandelo einjini yomoya, ixabiso lomgubo linokutsiba umlinganiselo wesihlanu nangaphezulu. Le asiyondawo ekunokutshipha ngayo ukuba inxalenye ifuna ukusebenza.
Emva koko kukho inxalenye yoyilo. Ijometri entsonkothileyo, edibeneyo enemicu yangaphakathi, iindonga ezibhityileyo, kunye ne-undercuts kulapho iMIM ikhanya khona. Kodwa 'intsonkothile' inezidanga. Isixhobo esincinci, esintsokothileyo sesixhobo sotyando sinokusebenzisa kuphela i-5 grams yemathiriyeli, kodwa ukuba ifuna iinkcukacha zesixhobo esiethe-ethe kunye ne-99.5% yoxinzelelo, ixabiso lokubumba inaliti yesinyithi ilawulwa kukuchaneka kwezixhobo kunye nolawulo lwenkqubo, hayi iigram ekrwada. Izixhobo zaloo malungu luhlobo lobugcisa ngokwalo.
Ndikhumbula iprojekthi yendlu yesivamvo efuna ukuba yi-hermetic. Uyilo lwaluneqokobhe eliqhubekayo, elinodonga olucekethekileyo. Ngokwethiyori, ifanelekile kwiMIM. Kodwa ukubaleka kokuqala kubonise i-microscopic porosity kumacandelo athile, ukungaphumeleli kuvavanyo loxinzelelo. Kwafuneka silungise uyilo lwesango kunye neprofayili ye-sintering, eyongeze imijikelo emininzi yolingo kunye neendleko. Isicatshulwa soqobo somthengi ngokwenxalenye nganye sasingenantsingiselo ngelo xesha. Iindleko zokwenene zibandakanya olo phuhliso luphindaphindayo.
ISinkhole Esifihlakeleyo: Imisebenzi yesibini
Kulapho uhlahlo lwabiwo-mali luhlala luvuthuza. Iphupha liyi-net-shape, kodwa inyani kumacandelo amaninzi ibandakanya umsebenzi othile wangemva kwe-sintering. Ukuba ufuna umphezulu owenziwe ngomatshini we-CNC wokwenyani kubuso obutywiniweyo, okanye umngxuma ochanekileyo ogrunjiweyo onokunyamezelwa okungqongqo kunokuba inkqubo yokucoca inokubambelela ngokuthembekileyo, wongeza amanyathelo. Inkampani ephethe zombini iMIM kunye CNC Machining endlwini, njengeQingdao Qiangsenyuan Technology Co., Ltd. (QSY), inenzuzo apha. Bangakwazi ukulungelelanisa ukuhamba komsebenzi ukusuka kwi-sintered blank ukuya kwinxalenye egqityiweyo phantsi kophahla olunye, oluhlala lulawula iindleko ezingcono kuneendawo zokuthumela kwivenkile yomatshini wesithathu.
Cinga ngomzimba wevalvu owenziwe nge-MIM. Ifom ephambili kunye nemijelo yangaphakathi iyabunjwa, kodwa ubuso be-flange bunokufuna ukucola kunye nemicu yezibuko idinga ukucofa. Ukuba umthengisi we-MIM kufuneka athathe ikontraka engaphantsi komatshini, ufumana uphawu kunye ne-logistics lag. Umthengisi odibeneyo unokwandisa ulandelelwano lwenkqubo-ngamanye amaxesha nokwenza umatshini ngaphambi kokuba i-sintering shrink yokugqibela ibalwe ngokupheleleyo-ukunciphisa inkunkuma kunye nokuphatha. Imbali yabo ende yokuphosa kunye noomatshini, njengoko kuphawuliwe kwindawo yabo tsngtaocnc.com, icebisa ukuba baqonde ezi ntlobo zeendleko zokwenza umxube.
Imijikelo yokubophelela kunye ne-sintering ngokwayo ziihagu zamandla. Ukuqhuba isithando somlilo kwi-alloy yobushushu obuphezulu njengomxube we-cobalt-chrome ayifani nentsimbi eqhelekileyo. Ixesha lomjikelo lide, i-atmospheric ilawula kubaluleke ngakumbi, kwaye ukunxiba kwesithando somlilo kuphezulu. Olu ncedo kunye neendleko zokuhla kwexabiso lezixhobo ezinkulu zifakwa kwinxalenye yexabiso, ngakumbi kwimithamo ephantsi.
Umthamo ligophe, hayi uTshintsho
Umgca weklasikhi yiMIM yeyomthamo ophezulu. Yinyani leyo. Yeyomthamo owaneleyo wokunciphisa ixabiso lezixhobo zokusebenza, elihlala liphezulu kunelokuphoswa kwefa elilula kodwa lisezantsi kunotyalo-mali oluchanekileyo. Indawo emnandi ihlala iqala malunga ne-10,000 lamacandelo ngonyaka, kodwa ndiyibonile ukuba iyavakala kumacandelo angama-5,000 ukuba ijometri isusa i-20 yeedola ze-CNC yokwenza kwiqhekeza ngalinye.
Ukwehliswa kweendleko ukusuka kwivolumu ye-10k ukuya kwi-100k ayihambelani. Uninzi lwemali eyongiwe ibanjwa yi-50k yokuqala. Emva koko, ucinezela imida kwaye ulungiselela ukuthengwa kwe-feedstock. Inzuzo yomthamo wangempela ikwinkqubo yokuzinza. Ekuqhubeni okuphezulu, abaqhubi bacofa iiparamitha, isixhobo sihlala, kwaye izinga lesiphako liyehla. Esi sivuno singaguqukiyo sisikhulu, esisoloko singenakulinganiswa, ukonga iindleko. I-Scrap kunye nokusebenza kwakhona kunokubulala inzuzo yecandelo eliphantsi kwexabiso eliphantsi.
Ukusilela esikufunde kuyo: isibiyeli sesixhobo somthengi. Sifumene i-quote ye-volume ye-100k yamaqhekeza, axhotyiswe, kwaye aqala imveliso. Inxalenye isebenzile, kodwa i-cosmetic spec ibiqina kunokuba besinombulelo ngokupheleleyo. Ukwahluka okuncinci kokutshintsha kombala kwiibhetshi, okwamkelekileyo kwinxalenye yeshishini, kwaba sisizathu sokwaliwa. Siye sagqiba ukongeza inyathelo lokugqibezela lokungcangcazela ebesingakhange silibize, sicima umda oqikelelweyo. I ixabiso lokubumba inaliti yesinyithi imodeli ayiphumelelanga ukunika ingxelo ngemfuno engasebenziyo.
UKhetho loMboneleli: Ukukwazi ngaphezulu kweNtengo
Ukukhetha umthengisi kwelona xabiso liphantsi ngokwenxalenye nganye yeyona ndlela ikhawulezayo yokulahlekelwa yimali. Kufuneka uphicothe ulawulo lwenkqubo yabo. Bakubeka esweni kwaye babuyekeze njani ukwahluka kwemfuyo yesondlo? Luthini ulawulo lwabo lwenkqubo yobalo (SPC) kwimilinganiselo ebalulekileyo? Kwifemu efana ne-QSY, engaphezulu kweminyaka engama-30 yokuphosa kunye noomatshini, umbuzo ngowokuba ulwazi lolawulo lwetsimbi kunye nobukhulu lugqithisela njani kwimisebenzi yabo ye-MIM. Loo mava kwi utyalo mali kwaye iqokobhe ngundo ukuphosa yee-alloys ezikhethekileyo zihambelana ngqo nokuqonda ukuziphatha kwe-sintering kunye neempawu zokugqibela zezinto eziphathekayo.
Ixesha elikhokelayo liyindleko, nayo. Umthengisi oneshedyuli yesithando somlilo unokubonelela ngeebhetshi eziphuthumayo okanye iimvavanyo zobunjineli ngaphandle kwentlawulo ye-50%. Le agility igcina iiprojekthi. Ndingathanda ukuhlawula ipremiyamu ye-10% kumboneleli onokujika ibhetshi yoyilo-yovavanyo kwiiveki ezimbini kunokulinda iiveki ezisibhozo kwivenkile efikelelekayo.
Buza ngeprothokholi yabo ye-scrap. Ngaba baphinda basebenzise i-sintered scrap njengemathiriyeli yomgangatho ophantsi, okanye ngaba banokuphinda bayibuyisele kumjelo we-feedstock phantsi komlinganiselo olawulwayo? Oku kuchaphazela ixabiso lakho lezinto eziphathekayo ekuhambeni kwexesha. Ukucaca apha kwahlula iivenkile zemisebenzi kumahlakani ezobugcisa.
Iyonke iNdleko Equation: Ukuyibuyisela
Ke, xa sijikeleza sibuyela kwixabiso lokubumba inaliti yesinyithi, sithetha ngenyani malunga nesimbuku: I-Amortization ye-Tooling + (Ixabiso le-Feedstock ngoShot + Ixabiso leNkqubo ngoMjikelo) / Ixabiso leSivuno + Iindleko zokuSebenza kweSekondari + uLogistics/Umphezulu. Uphoswa utshintsho olunye, kwaye imeko yeshishini lakho iyagungqa.
Ezona projekthi zeMIM zinexabiso eliphantsi zezo ziyilelwe inkqubo ukusuka kusuku lokuqala, kunye nenjineli esebenza ecaleni komenzi onamava. Kumalunga nokucacisa i-alloy efanelekileyo yomsebenzi, ukunyamezela kuphela iimpawu ezibalulekileyo, kunye nokuqonda ukurhweba. Umthengisi obonelela nge-suite epheleleyo-ukusuka kwingcebiso yezinto eziphathekayo ukuya ekubumbeni, ukuhlamba, kunye neyokugqibela CNC Machining-isoloko ifumana impumelelo ikhonkco lonikezelo eliqhekezayo elingenako.
Ekugqibeleni, iindleko zingqinelwa ngokusebenza kwenxalenye kunye nokonga kokuhlanganiswa. Ukuba utshintsha indibano yamalungu amahlanu ngoomatshini kunye necandelo le-MIM elinye, i ixabiso lokubumba inaliti yesinyithi iphantse ingabinamsebenzi xa ithelekiswa nendibano yabasebenzi, i-inventri, kunye neenzuzo zokuthembeka. Nantso inguqu yembono. Asinto ithengwayo; yintsebenziswano yobunjineli bexabiso. Inani lokugqibela kwi-invoyisi linqaku elinye nje ledatha kwelo balo likhulu kakhulu.
