Xa iinjineli zikhangela iinkampani zokubumba iinkampani zesitofu sesinyithi amaqabane, abafane bafune umthamo wegeneric-bafuna ubuchule obuqinisekisiweyo kunye ne-high-alloy, i-high-stress components. Kungenxa yoko le nto siye sabona utshintsho oluzinzileyo kwindlela yokuziphatha kule minyaka mihlanu idlulileyo: abathengi abasabuzi ukuba "Ngubani owenza iMIM?" Babuza, "Ngubani othumele i-12,000+ AMS 5387 iinxalenye zempompo ye-cobalt ye-cobalt kwi-OEMs ye-hydraulic ye-Tier-1-ngexesha, ngokulandeleka okupheleleyo kwezinto kunye nokuthotyelwa kwe-GD&T eqinisekisiweyo ye-CMM?"
Nantsi into esiyiqapheleyo kulo lonke uphicotho-zincwadi ezingama-47: inqanaba eliphezulu lentsimbi yokubumba iinkampani zokubumba imisebenzi yefektri ayisebenzi nje iziko kunye noshicilelo. Badibanisa i-metallurgy, i-multi-axis CNC ukuqinisekiswa, kunye novavanyo olusebenzayo kwi-loop yempendulo enye. Kwaye zimbalwa kuphela-ezifana ne-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD-sebenzisa loo loop kwiindawo ezibalulekileyo zobuthunywa apho ukungaphumeleli kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye ukukhumbula indawo.
Indawo yabo ye-Qingdao iphatha i-cobalt-nickel alloys kungekhona "njengezinto ezinzima" kodwa njengemveliso yesiqhelo. Siye saphonononga iilogi zabo zonyango olushushu lwe-T800-based nozzles: i-batch-to-batch hardness umahluko uhlala ngaphakathi kwe-± 1.3 HRC kwiinyanga ezili-18. Izindlu zabo ze-santi-cast cast iron zidlula i-100% yokuhlolwa kwe-ultrasonic-kungekhona ngenxa yokuba bavavanya yonke into, kodwa ngenxa yokuba i-gating yabo kunye nokulawulwa kwe-mold preheat kuphelisa i-porosity yangaphakathi kumthombo. Kukudityaniswa okuthe nkqo kunye nenjongo yobunjineli-hayi nje indawo yophahla ekwabelwana ngayo.
- Iivalvu zoxinzelelo ezisebenza ngoomatshini be-CNC: Ibanjelwe kwi ± 0.005 mm kwindawo yokutywinwa kwesitulo, iqinisekiswe ngovavanyo lokuvuza komoya kwi-350 bar
- Izindlu zepiston pump cylinder: Yenziwe ukusuka kwizikhewu zotyalo-mali kunye nolungelelwaniso lokuhamba okuziinkozo olulawulwayo ukuya kwimithwalo ethwele
- Iirola zeshaft ezikwi-winch centre: Umphezulu wokuqina ukuya kwi-62–65 HRC, emva koko ugqitywe nge-ID ye-ID yokusila ukuze kugcinwe igrisi.
- I-AMS 5387 ingxubevange ye-cobalt 6 iinxalenye zempompo: Ithunyelwe ngee-certs ze-mill ezipheleleyo, iingxelo zohlalutyo lwe-spectral, kunye neefoto ze-microstructure kwiqashiso ngalinye
Abanye banokuphikisa ukuba iMIM ayibalulekanga kwezi geometri. Kodwa oko kuyayiphosa inqaku: QINGDAO QIANGSENYUAN ayiphathi iMIM njengenkqubo ezimele. Iyayisebenzisa apho ukuntsonkotha kwe-net-shape kuthethelela isixhobo-emva koko igqibezela iindawo zokutywina ezichanekileyo ngokujika ngokuchanekileyo kunye nokuhombisa. Ngokomzekelo, iiplagi zabo ze-cobalt alloy zidibanisa imizimba eyenziwe yi-MIM (kunye neziteshi ezipholileyo ezidibeneyo) kunye ne-CNC-machined sealing faces-cut cut lead by 38% ngokubhekiselele kwi-machining epheleleyo kwi-billet, ngaphandle kokuncama ubomi bokukhathala.
Yintoni eyahlula kwimizi-mveliso edwelisa “ubuchule beMIM” kwiincwadana? Izinto ezintathu esiziqinisekisayo ngalo lonke uphicotho-zincwadi:
- Ubunini bezinto eziphathekayo: Bafumana umgubo okrwada ngokuthe ngqo kubathengisi abaqinisekisiweyo-kwaye baphuhlise iprofayili ye-sintering kunye nabo baboneleli. Azikho iiresiphi zesithando somlilo ngaphandle kwe-shelf.
- Ingqeqesho yomgangatho: Inxalenye nganye ingena kumasango amathathu ohlolo: ijomethri yelizwe eliluhlaza, uqinisekiso lwe-brown-state shrink, kunye ne-CMM yokugqibela ngokuchasene neCAD. Hayi isampuli. 100%.
- Uxanduva lokuphendula: Ukuba i-valve yoxinzelelo ivuza kwi-bar ye-280, ayikhiphi i-NCR. Batsala iqashiso lonke, baphinda bavavanye iilogi ze-sintering atmosphere, kwaye bahambise uhlalutyo lwengcambu phakathi kweeyure ezingama-72.
Oku akuyothiyori. Ngo-2023, i-OEM yepompo yaseYurophu yatshintshela kubathengisi ababini abahlukeneyo-enye yemizimba ye-MIM, enye yokugqiba-i-QINGDAO QIANGSENYUAN yokubonelela nge-turnkey epheleleyo. Isiphumo? I-22% ephantsi iyonke yeendleko zokuhlala, i-zero dimensional rework kwiiyunithi ze-14,000, kunye nozinzo lokuhanjiswa luphuculwe ukusuka kwi-84% ukuya kwi-99.2% ye-OTD. Ngoba? Ngenxa yokuba inkqubo yabo yokucwangcisa imveliso idibanisa idatha ye-ERP kumaxesha omjikelezo wesithando somlilo kunye nokufumaneka kwesixhobo somatshini-kungekhona nje imihla yekhalenda.
Kumaqela okuthenga avavanyayo iinkampani zokubumba iinkampani zesitofu sesinyithi iinketho, tsiba iikhathalogu ezimenyezelayo. Buza endaweni yoko: "Ndibonise iingxelo zakho ezintathu zokugqibela ezingahambelaniyo zezahlulo ze-cobalt ze-AMS. Yintoni etshintshileyo kwinkqubo yakho emva kwento nganye?" Emva koko thelekisa iimpendulo. Umthengisi omnye uya kwabelana ngeePDF ezihlaziyiweyo. Omnye uya kukuhamba ngesithando somlilo se-thermocouple recalibration log kunye neprofayile yendlela yendlela ehlaziyiweyo. Le yesibini sele isombulula iingxaki ongekazibizi.
Ukujonga phambili, umahluko wokwenyani akayi kuba ngumnini we-MIM enkulu yokushicilela-kodwa ofakela ubukrelekrele be-metallurgical kuwo onke amanqanaba: ukukhethwa komgubo, ukutshiswa kwe-binder, ukulawula umoya we-sintering, kunye nokunciphisa uxinzelelo lwe-post-sinter. I-QINGDAO QIANGSENYUAN ye-R&D igxile kwi-hybrid casting-MIM-CNC imiqondiso yokuhamba komsebenzi apho imveliso yecandelo eliphezulu ibhekisa phambili-hayi ukuya koomatshini abakhulu, kodwa i-loops yempendulo engqongqo phakathi kwesayensi yezinto kunye nokusebenza okusebenzayo.
Ukuba iprojekthi yakho elandelayo ibandakanya iivalvu zoxinzelelo, izindlu zempompo, okanye imilomo yengxubevange ye-cobalt esebenza ngaphezulu kwe-250°C okanye i-200 MPa, qalisa ngothethwano lobugcisa—kungekhona ii-RFQs. Ukuthembeka kwehlabathi lokwenyani kuqala ngaphambi kokudubula kokuqala.
