Xa iinjineli kunye nabaphathi beentengo befuna a Metal Injection Molding factory, abafuni nje ukukhangela umthamo-bafuna ukuthembeka kwe-dimensional, ukuhambelana kwezinto eziphathekayo, kunye nokusebenza okuqinisekisiweyo kwizicelo zoxinzelelo oluphezulu. Kodwa nantsi into efunyanwa ngabaninzi emva kwexesha: uninzi lweevenkile "ezinamandla e-MIM" ziphatha kuphela iijometri ezilula kwi-316L okanye i-17-4PH. Bambalwa abathembekileyo abaqhuba i-cobalt-nickel superalloys, bagcine ukulandeleka okupheleleyo kwiibhetshi eziphathwe ubushushu, okanye badibanise ukuphosa ngokucokisekileyo ukugqitywa kwe-CNC-konke kuphantsi kophahla olunye.
Kutheni Ukhetho Lwezinto eziphathekayo Luyalele Iqabane Lakho le-MIM—hayi nje Ukukwazi ukwenza inkqubo
Siye sabona abathengi bebuyela kathathu kumzobo ofanayo: okokuqala kwi-porosity kwi-AMS 5387 yezindlu zepompo, okwesibini kwi-microcracking emva konyango lobushushu, okwesithathu kwi-GD & T yokungahambelani kwi-interfaces yesitulo sevalvu. Ukungaphumeleli ngakunye kulandelelwe kunobangela omnye-hayi isixhobo esingalunganga, kodwa ulawulo lwetsimbi olungonelanga phezulu. Ukugqwesa kwe-MIM yokwenyani kuqala ngaphambi kokutofa: ukufunwa kwepowder eluhlaza eqinisekisiweyo, i-oxygen-controlled debinding, i-vacuum sintering kunye neeprofayili ezichanekileyo ze-ramp / soak, kunye ne-post-sinter HIP apho ifuneka khona.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza indawo ehambelana ne-ISO apho yonke i-cobalt alloy batch-ukusuka kwi-T800-based nozzles ukuya kwi-AMS 5387 i-piston components pump-ifumana uhlalutyo lwepowder engenayo (umxholo we-O / N / H, ukusabalalisa ubungakanani be-particle), ukuqinisekiswa kwe-green part density, kunye nokuqinisekiswa kwe-sintered density nge-Archimedes indlela. Akukho ngqikelelo. Akukho batch waivers. Oku akusiyo i-theater yokuthotyelwa-yindlela okhusela ngayo i-12% ye-shrinkage ye-shrinkage kwi-0.05 mm yokunyamezela ukunyamezela.
Udibaniso oluthe nkqo olunikezela ngozinzo-hayi nje amabango okuthengisa
Abanye ababoneleli bangaphandle benza i-sintering. Abanye balima oomatshini bokugqibela. Oko kuqhekeka kubulala ukuphinda-phinda kwe-dimensional. Silinganise iimpazamo eziqokelelweyo eziqokelelweyo ezingaphezulu kwe-±0.08 mm kubathengisi abathathu abaphethe indawo enye: ukuphosa → ukuthoba → ukucola → ukuqinisekiswa kweCMM.
EQINGDAO QIANGSENYUAN, utyalo-mali, iMIM, CNC machining, kunye nokugqiba umphezulu kwenzeka kwindawo enye elawulwayo. Umzimba wevalvu yoxinzelelo uyashukuma ukusuka kulungiselelo lwe-feedstock ukuya kwi-passivation yokugqibela ngaphandle kokuwela idokhi yokuthumela. Oko kuthetha ukuba ulawulo lwembali yobushushu obungqongqo, inkqubo ye-CMM yeelophu zengxelo, kunye ne-zero-induced micro-scratches ekutywineni. Umatshini wabo weeseli ze-CNC we-multi-axis ngokuthe ngqo kwiimilo ze-sintered ezikufutshane-akukho ukulungiswa kwesibini-kwaye basebenzise unyango lobushushu lwasekhaya kuphela apho ukuxhathisa ukudinwa kubaluleke kakhulu.
Oku kudityaniswa kunika iziphumo zokwenyani: I-92% inqanaba lokuphumelela inqaku lokuqala kwi-GD & T-impawu ezibalulekileyo; ukungaguquguquki kwe-Rockwell C58–62 kuzo zonke iirola zeshaft ze-T800; kunye nomphezulu ophindaphindwayo ugqiba ukuhla ukuya kwi-Ra 0.4 µm kwiindlela zokuqukuqela ze-cobalt ialloy-ingqinwe nge-optical profilometry, hayi uthelekiso olubonakalayo.
Apho uninzi lweefektri ze-MIM zisilela khona-kwaye iNdibaniselwano yobuNjineli iyilungisa njani
"Ungayenza lonto?" ngumbuzo wokuqala ongalunganga. Elona lifanelekileyo: "Lenza ntoni eli candelo * ekusebenzeni kwenqanaba lenkqubo?" I-winch center shaft roller ayikho nje i-cylinder ejikelezayo-yinto ejongene nomthwalo wokuhamba ngebhayisikile phakathi komthwalo wokuthuthumela kunye nokubonakaliswa kwamanzi etyuwa. Ijometri yayo kufuneka ilungelelanise ukugxininiswa koxinzelelo, ukugcinwa kwe-lubricant, kunye nokumelana nokubola.
I-QINGDAO QIANGSENYUAN ifakela uphononongo lobunjineli *phambi kokuba* kuqale isixhobo. Iqela labo libonisa imingcipheko yokwenziwa kwangaphambili: ukuguquguquka kodonga olumema i-warpage, ii-undercuts ezifuna i-electrode ye-EDM ebiza kakhulu, okanye i-radii eqinile kakhulu ukuhamba komgubo ngexesha lokutofa. Abavele bathi "ewe" -bacebisa ezinye iindlela ezixhaswa yi-FEA-eqinisekisiweyo yokulinganisa i-sintering. Impompo enye yaseMntla Melika i-OEM yanciphisa ixesha lokukhokela nge-40% emva kokutshintsha ukusuka kwi-"design-for-machining" ukuya kwi-MIM-friendly geometry edibeneyo.
Baphinde bagcine intsebenziswano yobugcisa kunye nabanikezeli bezinto eziqinisekisiweyo-kungekhona nje amaphepha, kodwa uphicotho oludibeneyo lwe-metallurgical. Xa umthengi echaza i-AMS 5387 ene-≤12 ppm sulphur yokuphucula ukumelana nokubola, i-QINGDAO QIANGSENYUAN ilungelelanise uvavanyo lwesiqinisekiso semathiriyeli ekrwada kunye nelebhu yomthengisi-emva koko yaqinisekiswa inxalenye yokugqibela yekhemistri nge-OES spectroscopy kwiqashiso ngalinye.
Ukukhetha i-Metal Injection Molding Factory yakho-Jonga iZatifikethi ezidlulileyo, Jonga izakhono
I-ISO 9001 ikuxelela ukuba ivenkile inomgangatho *wenkqubo*. Ayikuxeleli ukuba abaqhubi babo banokubamba i-± 0.015 mm kwi-120 mm ye-cobalt alloy housing ene-bores ezintandathu ezinqumlanayo. Buza endaweni yoko:
- Ngaba uyayenza inkqubo yokujonga ingxinano kuyo yonke i-sintered lot-hayi nje inqaku lokuqala?
- Ngaba unokubonelela ngokulandeleka okugcweleyo kwemathiriyeli ukusuka kwisatifikethi somgubo ukuya kwi-ID yecandelo eligqityiweyo, kubandakanya nezigodo zomjikelo we-sintering?
- Yiyiphi imveliso yakho ende kakhulu eqhutywe kwi-AMS 5387 okanye i-T800-kwaye yintoni i-CPK yee-diameters ezibalulekileyo kulolo hambo?
- Ngaba umatshini ususa ngokuthe ngqo iinxalenye ezifakwe emanzini-okanye ufuna ukulungiswa kwakhona kumgca we-CNC owahlukileyo?
I-QINGDAO QIANGSENYUAN TECHNOLOGY idibana nganye kwezi-kungekhona ngaphandle, kodwa njengesiqhelo. Ugxininiso lwabo luhlala luncinci: amacandelo esinyithi achanekileyo apho ukungaphumeleli akusiyo inketho-iivalve ze-hydraulic, izindlu zempompo, izixhobo ze-offshore. Abaleqi umthamo. Benza ukuphinda-phinda.
Iinjineli ezichaza iindawo ezingaphantsi koxinzelelo lwebar ezingama-300, kumaqondo obushushu angaphezu kwama-450°C, okanye atyhileke kudaka olurhabaxa—akho. Metal Injection Molding factory kufuneka wenze ngaphezu kokutofa umgubo wentsimbi. Kufuneka iqinisekise ubume, uzinzo, kunye nomsebenzi wenqanaba lenkqubo. Oko akufumaneki kwiincwadana. Ingqinwe kuyo yonke imibhobho ye-cobalt ene-sintered, yonke indlu yepiston eyenziwe ngoomatshini, yonke i-winch shaft ezisiwe-ngexesha, ukucacisa, kunye nokulandeleka okupheleleyo.
