Xa iinjineli zifuna imveliso yokubumba ngenaliti yesinyithi inkxaso yeendawo ezimele zibambe ukunyamezela kwe-± 0.01 mm phantsi kwe-300-bar yoxinzelelo lwe-hydraulic-okanye ukusinda kwi-800 ° C ngebhayisikile ye-thermal kwimizimba yevalvu ye-oilfield-ayiqali nge-RFQ eqhelekileyo. Baqala ngokuziphatha kwezinto eziphathekayo, ukusabalalisa uxinzelelo, kunye neendlela zokwenyani zehlabathi. Siyibonile: i-cobalt-nickel nozzle iqhekeziwe ngexesha lovavanyo lwentsimi-kungekhona kwimpazamo yoyilo, kodwa ngenxa yokuba i-microstructure ye-as-sintered yayingenakho ukudibanisa komda wengqolowa. Kulapho "omnye umboneleli weMIM" uyeka ukuba luncedo.
Kutheni i-MIM echaneke kakhulu ifuna ngaphezulu kwePowder + Cinezela
Ukubunjwa kwesitofu sesinyithi ayibobuchwephesha be-CNC. Yi-metallurgy eguqulwe njengemveliso. Uyondla umgubo wesinyithi ocolekileyo (ngokuqhelekileyo <20 µm), yibophe ngewax ye-thermoplastic, igalele kumngxunya, idibaniswe, emva koko i-sinter kumaqondo obushushu aphantse anyibilika. Inyathelo ngalinye litshintsha ukuxinana, ubungakanani bengqolowa, kunye noxinzelelo olushiyekileyo. Ukwahluka kwe-0.3% kumxholo wekhabhoni kwi-AMS 5387 cobalt alloy? Oko kutshintsha ubulukhuni ukusuka kwi-42 HRC ukuya kwi-48 HRC-kwaye ibulala ubomi bokukhathala kwizindlu zempompo zepiston. Sikuqinisekisile oku kwiimveliso ze-17 ezininzi. Iifektri ezininzi zithatha i-MIM “njenge-near-net-shape casting.” Eyona nto ingcono uyiphathe njengolawulo lwenguqu yesigaba sombuso oqinileyo.
Kungenxa yoko le nto ukuchaneka kokwenyani kuqala ngaphambi kokudubula kokuqala. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Iprojekthi nganye yeMIM iqala ngeetshekhi ezintathu ezingaxoxisiyo: isiqinisekiso semathiriyeli ekrwada (i-ASTM F2885 ye-cobalt alloys), i-binder burnout ramp profiling (kungekhona nje ixesha/ubushushu-kodwa izinga lokulahleka kobunzima nge °C), kunye nolawulo lwendawo yomoya we-sintering.<−40°C). Tsiba enye, kwaye uya kufumana amaqoqo e-porosity kwiingcambu zemisonto okanye idimensional drift kwiiflange zempompo zodonga olucekethekileyo. Asilukhupheli ngaphandle olu lawulo. Zakhelwe kwiziko lethu elithobela i-ISO eQingdao-apho iilayini zeMIM zihamba ecaleni kweeseli ze-CNC ezine-axis ezintlanu kunye neziko lokucoca ubushushu.
Apho iifektri zeMIM ezisemgangathweni zibetha udonga lwazo-kunye nendlela esiluwela ngayo
Abanye abathengi bayabuza: "Ngaba ungayenza le T800 cobalt alloy inxalenye ngeMIM?" Impendulo yethu ayinguye ewe okanye hayi. Likho: *Yintoni indlela yomthwalo osebenzayo?* Iplagi engajikiyo? Ewe-i-MIM inikezela ngoxinaniso olupheleleyo kunye namandla e-isotropic. I-high-speed center shaft roller ye-winch yemoto yobunjineli? Hayi-i-MIM iyodwa ayinakuqinisekisa ingqibelelo engaphantsi komhlaba efunekayo kwi-500,000-cycle torsional fatigue. Kulapho inkqubo ye-hybrid iqala khona: i-MIM preform + iijenali ezizele ngoomatshini + ukuqina komphezulu welaser kwiindawo zoqhagamshelwano.
Oku akuyothiyori. Sivelise i-12,400 AMS 5387 iinxalenye zempompo kulo nyaka uphelileyo sisebenzisa kanye olo landelelwano. Isivuno: 98.7%. Unobangela wokwaliwa? Amacandelo amabini asiphumelelanga ukuqinisekiswa kwe-CMM ekugxilweni kwe-bore-hayi ngenxa yokuncipha kwe-sintering, kodwa ngenxa yokuba indawo eluhlaza yonakalisiwe ngexesha lokuphatha ngaphambi kokuba idibaniswe. Ngoko sayila ngokutsha itreyi yenkxaso yeceramic. I-Real-world iteration ibetha izithembiso ze-spec-sheet ngalo lonke ixesha.
- Cobalt-nickel MIM iinxalenye: AMS 5387, T800, L605-eqinisekisiweyo ukulandeleka ukunyibilika ibhetshi
- Ulawulo lomgangatho: ± 0.3% ukunyamezela ukucutheka komda, kuqinisekiswe ngokwe ASME Y14.5 GD&T
- Umphezulu imfezeko: As-sintered Ra ≤ 3.2 µm; i-post-machined Ra ≤ 0.4 µm kwiindawo ezibalulekileyo zokutywina
- Ukuqinisekiswa okusebenzayo: Uvavanyo loxinzelelo kwi-1.5 × uxinzelelo lokusebenza, uvavanyo lokuvuza kwe-helium <1×10⁻⁹ mbar·L/s
Ayizizo Zonke "Isiko" Elithetha "Ukulawulwa"-Nantsi Eyona nto Ishukumisa Inaliti
Igama elithi "isiko" lisetyenziswa kakubi. Umzi-mveliso olungisa indawo yesango okanye otshintsha ixesha le-sintering wenza ngokwezifiso. Umzi-mveliso ophuhlisa iprofayile yakho yokwandisa ubushushu kunye nemvulophu yokusebenza yenkqubo yakho yenza ulawulo. Senza okokugqibela.
Umzekelo: indlu yevalve yoxinzelelo ifuna ukukhula okushushu okungafaniyo phakathi komzimba wentsimbi engatyiwayo kunye nokufakwa kwesitulo se-cobalt alloy. I-MIM eqhelekileyo inokwenza i-7.2 ppm/°C umahluko—okwaneleyo ukubangela ukuvuza kwi-120°C. Isisombululo sethu? I-Gradient sintering-indawo yobushushu esezantsi yojongano lwesihlalo, phezulu kwiindonga zesakhiwo-kunye ne-post-sinter-relief annealing. Isiphumo: ukungahambelani kwehliselwe ku-0.9 ppm/°C. Ingqinwe ngolungelelwaniso lomfanekiso wedijithali (DIC) ubunzima bemephu.
Eli nqanaba lokungenelela lisebenza kuphela ngokudibanisa ngokuthe nkqo. Singabanikazi belebhu yokulinganisa umgubo, iinqanawa zomlilo ezitshisayo, i-CMM metrology suite, kunye nomgca wokugqibela wokudityaniswa. Akukho handoffs. Akukho zithuba zedatha. Iqela elinye lobunjineli elilandela umxholo weoksijini, i-pore morphology, kunye namandla okuqina ukusuka kwi-ID yeqashiso ukuya kwi-manifest yokuthumela.
Ukukhetha iFactory yakho yeMetal yokuBumba iSitofu yeMetal ayikuko malunga nomthamo-Kumalunga noMxholo.
Ukuba inxalenye yakho isebenza kwiinkqubo ze-hydraulic, izixhobo ze-oyile kunye negesi, okanye iindibano zempompo eziphezulu-kwaye zifuna i-cobalt alloys, i-GD & T eqinile, okanye ukuqinisekiswa okusebenzayo ngaphaya kwemilinganiselo yokushicilela-ufuna ngaphezu komthengisi. Udinga iqabane elithetha i-metallurgy ngokutyibilikayo, eliphatha i-sintering njenge-chemical reaction, kunye nokulinganisa impumelelo ngamazinga okusilela ebaleni-hayi nje isivuno sokuqala sokupasa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. wakha loo mandla yonke imihla. Akunjalo njengebango lokuthengisa-kodwa njengamaphepha enkqubo ebhaliweyo, iingxelo zophicotho-zincwadi zeqela lesithathu, kunye ne-237 ithumele amaninzi amacandelo e-MIM angaqhelekanga ukususela kwi-Q1 2023. Isinyathelo esilandelayo asiceli isicatshulwa. Ithumela umzobo wakho we-GD&T ukuze uphonononge ukwenziwa kwakhona-kunye ne-0 ye-NDA yokruthakruthwano, i-zero yentelekelelo yexesha elikhokelayo, kunye nokunyamezelwa kwe-zero kuqikelelo.
Ngenxa yokuba kwi-high-precision metal injection molding, umehluko phakathi "kwemisebenzi" kwaye "ayiyi kuphumelela" ilinganiswa kwii-microns, imizuzu, kunye nesayensi yezinto eziphathekayo-kungekhona iziqulathi zokuthengisa.
