I-high-precision metal injection molding (MIM) ifuna okungaphezulu nje komatshini-ifuna umzi-mveliso ocinga njengenjineli, uvavanyo olunjengomphicothi-zincwadi osemgangathweni, kwaye uhambise njengomthengisi obalulekileyo. Nangona kunjalo abathengi abaninzi bafuna i umatshini wokubumba umatshini wokubumba wesinyithi betha udonga olufanayo: abathengisi abathengisa i-hardware kodwa bengenalo ulawulo lwe-metallurgical olunzulu, ukulandelwa kwenkqubo, okanye ukuqinisekiswa okucacileyo kwesicelo-ingakumbi kwiindawo ezisebenza phantsi koxinzelelo oluphezulu, ukunxiba okugqithisileyo, okanye indawo enobungozi.
Sizibonele mathupha: impompo yaseMntla yaseMelika i-OEM ilibazisekile ukuqaliswa kweeveki ze-11 kuba iqabane labo le-MIM alikwazanga ukubamba ± 0.02 mm kwi-AMS 5387 cobalt alloy nozzles. Omnye umxhasi ulahle i-63% yemveliso yokuqala eqhutywe emva kokuba i-microcracks yomphezulu ibonakala emva kwe-sintering-ilandelwa kwimijikelezo yokutshisa i-binder engaguqukiyo kunye nemephu engaqinisekanga yobuninzi obuluhlaza. Ezi ayingomngcipheko wethiyori. Zizintsilelo eziphinda-phindayo ezimiliselwe kubuchule obuqhekekayo: ukuthengisa iivenkile ezithengisa ngaphandle, izindlu ezisebenza ngomatshini ezinamava esinyithi engumgubo, okanye ababoneleli “benkonzo epheleleyo” abanikezela ngamanyathelo angundoqo e-MIM ngaphandle kobunini benkqubo ekwabelwanayo ngayo.
Inyaniso ye-MIM yokwenyani iqala ixesha elide phambi kokuba ushicilelo luvale
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha ukubumba inaliti yesinyithi njengenkqubo evaliweyo-kungekhona inyathelo elinye. Indawo yethu ethobela i-ISO e-Qingdao idibanisa uphuhliso lwe-feedstock, uyilo lwesixhobo sokutofa, ukuxilonga iprofayili ye-kinetics, i-vacuum sintering kunye nemilinganiselo ye-ramp ye-atmospheric elawulwayo, kunye nokugqitywa kwe-CNC yokugqibela-konke phantsi kophahla olunye kunye neprotocol yomgangatho omnye. Oko kuthetha ukuba akukho handoffs, akukho batch-to-batch guesswork, kwaye akukho kuyekelela kuzinzo lwedimensional kumalungu afana nezindlu zepiston pump cylinder okanye imizimba yevalvu yoxinzelelo apho ukutenxa nge-0.015 mm kubangela ukusilela kokusebenza.
Siqinisekisa yonke into eninzi yemathiriyeli-hayi ngokuchasene namaphepha athile, kodwa ngokuchasene nokuxinana kwe-sintered yokwenyani, ukuhanjiswa kobungakanani beenkozo, kunye nesivuno esiqinileyo kubushushu benkonzo. Kwii-alloys ezisekelwe kwi-cobalt ye-T800, sibeka iliso kwi-carbon pickup ngexesha lokuthunga sisebenzisa i-oxygen probes e-intanethi kunye nokujonga nge-post-process EPMA mapping. Ukuba umgubo okrwada ubonisa nokuba ngu-0.003% umahluko kumxholo we-nickel, siyawuvalela wedwa phambi kokuba sondle umxhubi. Oku akukho overkill. Yindlela esiqinisekisa ngayo i-99.4% isivuno sokuqala sokupasa kwiimpompo ze-AMS 5387-nangona kwiiyunithi ze-120 + kwibhetshi nganye.
Ukudityaniswa ngokuthe nkqo akusiyo i-buzzword-luhlahlo lwabiwo-mali lwakho lokunyamezela
Uninzi lweefektri ze-MIM zimisa kwindawo yokuhanjiswa kwe-sintered. Asazi. Kuba sikwasebenza ngoomatshini, siphatha ubushushu, kwaye sigqibezela ngaphakathi, sakha ulawulo lwejometri kulo lonke umlambo wexabiso:
- CNC Machining ye-sintered blanks ene-multi-axis contouring-ebambe ii-callouts ze-GD & T njengendawo eyinyani Ø0.05 mm kwiimpawu ezibalulekileyo zedatum;
- I-post-sinter stress relief zibekwe ixesha ngokuchanekileyo ukuphepha ukugqwetheka kwizindlu zesilinda ezibhityileyo;
- Ukugqitywa komphezulu ehambelana nomsebenzi-hayi ubuhle-njengeRa 0.2 µm ipolishi yesipili yobuso obumanzi okanye ukuthungwa kwegrit-blast elawulwayo yokuncamathelisa kokutshiza kwe-thermal;
- Ukulandeleka ngokupheleleyo: Inxalenye nganye iphethe i-ID ye-laser-etched edityaniswe nesatifikethi sayo sempuphu ekrwada, i-sintering log, ingxelo ye-CMM, kunye nedatha yokugqibela yovavanyo olusebenzayo.
Oku kuphelisa ukupakishwa kokunyamezela okubulala ukusebenza kwiinkqubo ze-hydraulic. Xa i-winch center shaft roller kufuneka ijikeleze kwi-1,800 RPM ngelixa ithwele i-42 kN axial load, awukwazi ukufikelela ± 0.03 mm drift phakathi kwe-sintered OD kunye nejenali yokuzala egqityiweyo. Udinga iqela elinye elingumnini wemicron nganye.
Ukuqinisekiswa kwehlabathi lokwenyani koyisa i-lab specs ngalo lonke ixesha
Abathengi bayabuza: “Ngaba eyakho umatshini wokubumba umatshini wokubumba wesinyithi Uphathe i-cobalt-nickel alloys ngaphandle kwe-micro-porosity? Impendulo yethu ayisiyiyo i-database-yingxelo yovavanyo evela kwisicelo se-oilfield ephilayo. Kwi-Q3 2023, sazisa iiplagi ze-cobalt alloy ezingama-217 kwikontraka yokomba ekude nonxweme. Emva kweenyanga ze-14 zokuvezwa ngokuqhubekayo kudaka lwe-H₂S-saturated kwi-150 ° C kunye ne-10,000 psi, iiyunithi zero zibonise ukugoba okanye ukulahlekelwa kwamandla okutywinwa. Imfihlelo? Ayisiyiyo nje ibakala le-alloy-yayiyiprofayile yethu yokubophelela, eye yanciphisa intsalela yekhabhoni nge-41% xa kuthelekiswa nemijikelo yeendlela ezisezantsi, kunye nexesha lethu lokuhlala elilungelelaniselwe ukuxinana kwefestile ye-cobalt.
Siphinde silungise izinto ezingahoywayo ngabanye. Iinkqubo zeMIM ezisemgangathweni zihlala zisilela kwiijiyometri ezingekho mgangathweni-njengemisonto yangaphakathi enzulu kune-3 × ubukhulu okanye iimpawu ezisezantsi ezifuna inkxaso yesiko leceramic. Siphuhlise indlela ye-hybrid: i-sinter kufuphi ne-net shape, emva koko sebenzisa i-wire-EDM yokunyaniseka kwentambo kunye ne-micro-polish yokulawula i-root radius. Isiphumo? Imisonto egqithisa i-100% yokuvavanya i-torque esebenzayo, kungekhona nje ukuhamba / akukho-ukuhlola i-gage.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayithengisi oomatshini. Sihambisa izinto zentsimbi ezichanekileyo ezenzelwe isiphumo. Nokuba ulinganisa umbhobho we-AMS 5387 okanye ulinganisa ukuya kwiiyunithi ezingama-5,000/ngenyanga yeziseko zempompo yentsimbi, amandla ethu alele ekwenzeni izinto ezimbalwa-kodwa ukuzenza ngokuphindaphindwa okubhaliweyo, uqeqesho lwesinyithi, kunye nokunyamezela iingqikelelo. Ukuchaneka ayisosetingi kumatshini. Sisambuku saso sonke isigqibo esenziweyo-kwaye saqinisekiswa-phambi kwenxalenye yokuqala yeenqanawa.
