Uma amaklayenti ebuza 'ngezindleko zokubumba umjovo wensimbi', ngokuvamile asuke ethemba inombolo elula yengxenye ngayinye. Lowo umbono oyiphutha wokuqala. Izindleko akuyona intengo yesitikha; yingxoxo eqala ngemodeli ye-CAD bese iphetha ngombiko wokugcina wokuhlola. Imayelana nezindleko eziphelele zobunikazi bengxenye esebenzayo, hhayi nje i-oda lokuthenga. Ngibone amaphrojekthi amaningi efa ngenxa yokuthi isilinganiso sokuqala sasibukeka sisihle, kodwa izindleko ezifihliwe zokusebenza kwesibili, izinkinga zekhwalithi, nokulibaziseka kwesikhathi sokuhola akuzange kufakwe phakathi. Ake sihlukanise ukuthi yini ngempela ehambisa inaliti.
Iqala nge-Feedstock ne-Geometry
Izindleko zempahla eluhlaza ye-MIM feedstock—leyo nsimbi eyimpushana exutshwe nesibophezelo—kuyithikithi lokungena. Kodwa ukukhetha kwe-alloy ngokushesha kuhlukanisa indlela. Ufuna i-17-4PH ejwayelekile? Kuyabikezelwa. Kodwa lapho isicelo sidinga i-nickel-based noma ingxubevange esekelwe cobalt ukumelana nezinga lokushisa eliphezulu, njengakwezinye izingxenye ze-turbine, izindleko zempushana zingagxuma ngesilinganiso esiyisihlanu noma ngaphezulu. Lena akuyona indawo eshibhile uma ingxenye idinga ukusebenza.
Bese kuba nomklamo wengxenye. Ijiyomethri eyinkimbinkimbi, ehlangene enezintambo zangaphakathi, izindonga ezincane, nama-undercuts yilapho i-MIM ikhanya khona. Kodwa 'inkimbinkimbi' ineziqu. Ingxenye yethuluzi lokuhlinza elincane, eliyinkimbinkimbi ingase isebenzise kuphela amagremu angu-5, kodwa uma idinga imininingwane yamathuluzi entekenteke kanye nokuminyana okungu-99.5%, Izindleko zokubumba umjovo wensimbi ibuswa ukunemba kwamathuluzi nokulawula inqubo, hhayi amagremu aluhlaza. Ithuluzi lezingxenye ezinjalo liyifomu lobuciko ngokwalo.
Ngikhumbula iphrojekthi yendlu yezinzwa eyayidinga ukuba i-hermetic. Umklamo wawunegobolondo eliqhubekayo, elinezindonga ezincane. Ngokombono, ilungele i-MIM. Kodwa ukugijima kokuqala kubonise i-microscopic porosity ezigabeni ezithile, yehluleka ukuhlolwa kwengcindezi. Kwadingeka silungise ukwakheka kwesango kanye nephrofayili ye-sintering, engeze imijikelezo eminingana yokuzama kanye nezindleko. Ukucaphuna kwangempela kweklayenti ngengxenye ngayinye kwakungasho lutho ngaleso sikhathi. Izindleko zangempela zazihlanganisa lokho kuthuthukiswa okuphindaphindiwe.
I-Sinkhole Efihliwe: Imisebenzi Yesibili
Kulapho-ke izabelomali zivame ukushaywa umoya. Iphupho liyi-net-shape, kodwa iqiniso lezingxenye eziningi lihilela umsebenzi othile we-post-sintering. Uma udinga indawo engaphezulu eyenziwe ngomshini we-CNC ebusweni obuvalekayo, noma imbobo eqondile embozwe ngokuqinile kunokuba inqubo ye-sintering ingabambelela ngayo, wengeza izinyathelo. Inkampani ephethe kokubili i-MIM kanye CNC imishini endlini, njenge-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunenzuzo lapha. Bangakwazi ukuqondisa ukuhamba komsebenzi kusukela kokungenalutho okuhlanganisiwe kuya engxenyeni eqediwe ngaphansi kophahla olulodwa, okuvamise ukulawula izindleko kangcono kunokuthumela izingxenye esitolo semishini yenkampani yangaphandle.
Cabanga ngomzimba we-valve owenziwe nge-MIM. Ifomu eliyinhloko namashaneli angaphakathi kuyabunjwa, kodwa ubuso be-flange bungase budinge ukugaywa futhi imicu yembobo idinga ukuthepha. Uma umthengisi we-MIM kufanele akhiphe inkontileka encane yomshini, uthola i-markup kanye ne-logistics lag. Umphakeli ohlanganisiwe angakwazi ukuthuthukisa ukulandelana kwenqubo—ngezinye izikhathi aze enze imishini ngaphambi kokuba i-sintering shrink ibalwe ngokugcwele—ukuze kuncishiswe imfucuza nokubamba. Umlando wabo omude ekulingiseni nasekukhiqizeni imishini, njengoba kuphawulwe esizeni sabo tsngtaocnc.com, iphakamisa ukuthi baqonde lezi zindleko zokukhiqiza ezixubile.
Imijikelezo ye-debinding kanye ne-sintering ngokwayo izingulube zamandla. Ukusebenzisa isithando somlilo sengxubevange yokushisa okuphezulu njengengxube ye-cobalt-chrome akufani nensimbi evamile. Isikhathi somjikelezo side, umkhathi ulawula okubaluleke kakhulu, futhi ukugqokwa kwesithando somlilo kuphakeme. Lezi zindleko ezisetshenziswayo kanye nezindleko zokwehla kwentengo zifakwa enanini lengxenye, ikakhulukazi kumavolumu aphansi.
Ivolumu iyijika, ayishintshi
Umugqa wakudala uthi i-MIM owevolumu ephezulu. Lokho kuyiqiniso ngokwengxenye. Owevolumu eyanele ukuze kuncishiswe izindleko zamathuluzi angaphambili, ngokuvamile aphezulu kunokusakaza okufayo okulula kodwa okuphansi kunokunemba kokusakazwa kokutshalwa kwezimali. Indawo emnandi imvamisa iqala cishe izingxenye eziyi-10,000 ngonyaka, kodwa ngibone kunengqondo ngezingxenye eziyi-5,000 uma ijometri isusa umshini we-CNC ongabiza u-$20 esiqeshini ngasinye.
Ukwehliswa kwezindleko ukusuka kuvolumu engu-10k kuye ku-100k akukona umugqa. Ukonga okuningi kubanjwa ngo-50k wokuqala. Ngemuva kwalokho, ucindezela kakhulu amamajini futhi uthuthukisa ukuthengwa kwe-feedstock. Inzuzo yevolumu yangempela isekuzinzeni kwenqubo. Ekugijimeni okuphezulu, opharetha badayela amapharamitha, ithuluzi liyahlala, futhi izinga lokungasebenzi liyehla. Lesi sivuno esingaguquguquki singonga izindleko ezinkulu, ngokuvamile ezingenakulinganiswa. I-Scrap kanye nokusebenza kabusha kungabulala inzuzo yengxenye ebiza kancane.
Ukwehluleka esikufunde kukho: kubakaki bedivayisi yomthengi. Sithole isilinganiso sevolumu yezingcezu eziyi-100k, sahlanganiswa, futhi saqala ukukhiqiza. Ingxenye isebenzile, kepha i-cosmetic spec ibiqinile kunalokho ebesikuthokozela ngokugcwele. Ukushintshashintsha okuncane kombala kumaqoqo, okwamukelekayo engxenyeni yezimboni, kube isizathu sokwenqaba. Sigcine ngokungeza isinyathelo sokuqeda sokudlidliza ebesingasibizanga, sisula umkhawulo ohlongozwayo. I Izindleko zokubumba umjovo wensimbi imodeli yehlulekile ukuphendula ngemfuneko engasebenzi.
Ukukhethwa Komhlinzeki: Ikhono Ngaphezu Kwekhwothi
Ukukhetha umdayisi ngentengo ephansi kakhulu yengxenye ngayinye kuyindlela eshesha kakhulu yokulahlekelwa yimali. Udinga ukuhlola ukulawulwa kwenqubo yabo. Bagada futhi bakunxephezele kanjani ukwehluka kwe-feedstock lot? Iyini i-statistical process control (SPC) yabo kubukhulu obubalulekile? Enkampanini efana ne-QSY, eneminyaka engaphezu kwengu-30 ekulingeni nasekukhiqizeni imishini, umbuzo uwukuthi lolo lwazi lokulawula okusansimbi nobukhulu ludlulisela kanjani emisebenzini yabo ye-MIM. Lokho okuhlangenwe nakho ku ukutshala imali futhi ukubunjwa kwegobolondo Ama-alloys akhethekile afaneleka ngokuqondile ekuqondeni ukuziphatha kwe-sintering kanye nezakhiwo zokugcina ezibonakalayo.
Isikhathi sokuhola siyisici sezindleko, futhi. Umhlinzeki onohlelo lwesithando somlilo angakwazi ukuthwala amaqoqo aphuthumayo noma ukuhlolwa kobunjiniyela ngaphandle kwenkokhiso engu-50%. Lokhu kushesha kusindisa amaphrojekthi. Ngincamela ukukhokha iprimiyamu engu-10% kumphakeli ongakwazi ukushintsha iqoqo le-design-of-experiment emasontweni amabili kunokulinda amaviki ayisishiyagalombili ukuze athole isitolo esishibhile.
Buza ngephrothokholi yabo ye-scrap. Ingabe bavele basebenzise kabusha izinsalela ze-sintered njengento yezinga eliphansi, noma bangaphinde balethe emfudlaneni wesitoko ngaphansi kwezilinganiso ezilawulwayo? Lokhu kuthinta izindleko zakho zempahla ngokuhamba kwesikhathi. Ukungafihli lapha kwehlukanisa izitolo zemisebenzi kozakwethu bezobuchwepheshe.
Isamba Sesibalo Sezindleko: Ukuyibuyisela
Ngakho-ke, lapho sijikeleza sibuyela ezindlekweni zokubumba umjovo wensimbi, sikhuluma ngempela ngesamba: I-Tooling Amortization + (Izindleko ze-Feedstock Ngokudutshulwa ngakunye + Izindleko Zenqubo Ngomjikelezo ngamunye) / Izinga Lokukhiqiza + Izindleko Zokusebenza Kwesibili + Logistics/Okuphezulu. Uphuthelwa okuhlukile okukodwa, futhi icala lakho lebhizinisi liyantengantenga.
Amaphrojekthi e-MIM angabizi kakhulu yileyo eklanyelwe inqubo kusukela ngosuku lokuqala, lapho unjiniyela esebenza eceleni komkhiqizi osemnkantshubomvu. Imayelana nokucacisa ingxubevange efanele yomsebenzi, ukubekezelela izici ezibalulekile kuphela, nokuqonda ukuhwebelana. Umhlinzeki ohlinzeka nge-suite ephelele-kusuka ngezeluleko zezinto ezibonakalayo ukuya ekubumbeni, ekusikeni, nasekugcineni CNC imishini-ivame ukuthola ukusebenza kahle uchungechunge lokuhlinzeka oluhlukene olungakwazi.
Ekugcineni, izindleko zivunyelwa ukusebenza kwengxenye nokonga kokuhlanganiswa. Uma ushintsha ukuhlanganiswa kwezingxenye ezinhlanu zomshini ngengxenye eyodwa ye-MIM, i Izindleko zokubumba umjovo wensimbi cishe ayibalulekile uma iqhathaniswa nezinzuzo zabasebenzi bomhlangano, i-inventory, kanye nokwethembeka. Yilokho ukushintsha kombono. Akukona ukuthengwa kwempahla; wubambiswano lonjiniyela. Inombolo yokugcina ku-invoyisi iyiphuzu elilodwa nje ledatha kuleso sibalo esikhulu kakhulu.
