Xa iinjineli kunye nabaphathi bokuthengwa kwempahla befuna metal naliti yokubumba abathengisi ifektri, abafane bafune uluhlu lwamandla egeneric okanye iincwadana ezinemibala eqaqambileyo. Bafuna ubungqina-ubungqina bokuba iqabane lingakwazi ukubamba ukunyamezela kwe-± 0.01 mm kwisihlalo sevalve ye-cobalt-nickel, ukuhambisa izindlu zepompo ze-AMS 5387 kunye ne-microstructure traceability epheleleyo, kunye nokusombulula iingxabano ze-GD & T ngaphambi kokusikwa kwesixhobo sokuqala. Ayingobuchule bethiyori leyo. Leyo yinkqubo yokusebenza.
Kutheni "Ukubunjwa kwesitofu sesinyithi" Yedwa sisigama sokukhangela esiLahlekisayo
Abathengi abaninzi bachwetheza "ifektri yokubumba isitofu sesinyithi" kuGoogle-kunye nomhlaba kubathengisi abakhupha i-sintering, ukutsiba isatifikethi semathiriyeli, okanye ukunqongophala kwe-metrology yangaphakathi. Kodwa nantsi into efundiswa kukuthunyelwa kwehlabathi lokwenyani: I-MIM inokuthenjwa kuphela njengolawulo lwealloyi, ukuchaneka konyango lobushushu, kunye nokuqinisekiswa komda emva kwayo. Inxalenye eyenziwe kwi-T800 ye-cobalt-based alloy ayiphumeleli kwi-ejection-kodwa xa ibhayisikili ye-thermal ibonisa ukusabalalisa okungahambelaniyo komda we-carbide. Siye sabona iibhetshi ezintathu ezingaphumeleliyo kumboneleli omnye kuba ii-certs zemathiriyeli ekrwada zamkelwa ngaphandle kokuqinisekisa i-AMS 5387 ye-tensile ye-tensile isasazeka kuwo wonke ubushushu. Ukuthembeka kokwenyani kuqala ngaphambi kokuba i-feedstock ingene kwi-hopper.
Izakhono ezine ezingaxoxisiyo kufuneka uziqinisekise
Sukubuza "Ngaba uyayenza iMIM?" Buza endaweni yoko:
- Ngaba unokuqinisekisa ikhemistri yealloy nge-ASTM E353 *phambi kokuba * idibaniswe? Hayi nje ii-certs ze-mill-eyokwenene ze-OES okanye i-ICP-MS iingxelo ezibotshelelwe kwinombolo yakho yeqashiso.
- Ngaba udibanisa i-HIP (i-Hot Isostatic Pressing) kunye nonyango lobushushu be-post-sinter kumjikelo omnye olawulwayo we-atmosphere? Ukutsiba eli nyathelo kushiya i-porosity eshiyekileyo kuxinzelelo oluphezulu lwempompo-nokuba i-CMM ithi imilinganiselo "icacisiwe."
- Ngaba yonke indawo ilinganiswa nge-CMM *kunye* nesithelekisi esibonakalayo ngokuchasene neefowuni zakho ze-GD&T-hayi nje imilinganiselo yomgca? Sakhe safumana impazamo yendawo eyi-0.04 mm kubuso obunyusela umbhobho obugqithise iitshekhi zecaliper kodwa yabangela ukuvuza kwetywina phantsi kwebha ye-350.
- Ungabonelela ngokulandeleka okugcweleyo: ubushushu obuninzi → igophe le-sinter → iiparamitha ze-HIP → imephu yobulukhuni bokugqibela? Hayi nje isitampu sePDF. Iifayile zedatha ekrwada, zifakwe isitampu sexesha, zigcinwe iminyaka eyi-10+.
Ezi ayizo "izinto ezintle zokufumana." Zizithintelo zokuthintela ukusilela.
Apho ukuDityaniswa kwe-Casting-Machining iba nguMgangatho wakho woMgangatho
Nantsi into engayi kukuxelela iivenkile ezininzi ze-MIM kuphela: imizimba entsonkothileyo yevalvu yehydraulic ihlala ifuna ukwenziwa komxube. Ijometri yangaphandle? Ilungiselelwe iMIM. Umhlaba obalulekileyo wokutywina kunye nemiphetho yamazibuko? I-CNC-igqitywe emva kokuba i-sintering iqinisekisa i-Ra ≤ 0.4 µm kunye ne-zero burr. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngolu hlobo-kungekhona njengebango lokuthengisa, kodwa njengesiqhelo semihla ngemihla. Indawo yabo ethobela i-ISO iqhuba ukuphosa utyalo-mali, ukuphosa isanti, umatshini we-multi-axis, kunye ne-MIM-derived near-net-shape processing phantsi kophahla olunye. Kutheni ibalulekile nje loo nto? Ngenxa yokuba ukwanda kwe-thermal ukungahambelani phakathi kweendawo ezishiyiweyo kunye nezingoomatshini ziyanyamalala xa zombini imisebenzi yabelana ngolawulo olufanayo lokusingqongileyo, ishedyuli efanayo yokulinganisa i-CMM, kunye ne-metallurgist efanayo ephonononga iimicrographs.
Sikuvavanye oku ngendlu yepiston yepompo yesilinda efuna i-0.015 mm cylindricity kwibhore eyi-120 mm. Abakhuphisana bacaphune izisombululo ze-MIM kuphela kunye nokugaya okwesibini-ukongeza iiveki ze-3 ixesha lokuhamba kunye nomngcipheko wokuphazamiseka. Indlela ye-QINGDAO yasebenzisa i-MIM kwiqokobhe, emva koko yagqiba-yadikwa kwaye yalola i-bore kwiseti enye yokubambelela kwileyile ye-CNC ezinzileyo. Isiphumo: I-98% isivuno sokuqala sokupasa, akukho msebenzi kwakhona, amaxwebhu apheleleyo okuthotyelwa kwe-ASME B16.34 afakiwe.
Jonga Ngaphaya Kwecatshulo-Hlola Inkqubo Engqongqo
Ixabiso elikhuphisanayo alithethi nto ukuba iplagi yakho ye-AMS 5387 cobalt alloy ifika kunye nomxholo ongaxelwanga we-delta ferrite ngaphezu kwe-3%. Okanye ukuba ukugqitywa komphezulu kuyahluka kwi-batch-to-batch kuba iiparamitha zokugqiba ukungcangcazela azilogwanga okanye zilungelelaniselwe inxalenye yejometri. Ukuthembeka kokwenene kubonisa kwindlela yophicotho-kungekhona i-invoyisi.
Iiprothokholi zokuhlola ezibhaliweyo ze-QINGDAO QIANGSENYUAN zifuna: ukuqinisekiswa kwezinto ezingenayo (i-OES + ubulukhuni), ukuhlolwa kwe-sinter density in-process (indlela ye-Archimedes), i-post-HIP ultrasonic scanning for subsurface voids, kunye novavanyo lokugqibela olusebenzayo-njengeemvavanyo zokubola koxinzelelo kwi-1.5 × ingcinezelo yokusebenza kuzo zonke iindibano zevalve. Ingxelo nganye iphethe isazisi sobuchwephesha, inombolo yesiriyali yesixhobo, kunye nomhla omiselweyo wokulinganisa. Akukho ngaphandle.
Oku akusiyo i-bureaucracy. Yindlela othintela ngayo ukusilela kwi-oyile kunye nezixhobo zokuthoba igesi apho ukutshintshwa kuthetha i-2M / imini yokuphumla.
Inyathelo lakho elilandelayo ayisiyiyo enye i-RFQ-luPhononongo lobuGcisa
Phambi kokuba uthumele imizobo, cela zabo iphakheji yengxelo yokwenziwa: Amanqaku okutolika kwe-GD & T, ii-angles ezicetyisiweyo ze-MIM ejection, enye i-alloy trade-offs (umzekelo, i-T800 vs. IN718 yokumelana nokunxiba vs. machinability), kunye nokukhethwa kokulandelelana kwonyango lokushisa. Yinyani metal naliti yokubumba abathengisi ifektri iphatha uyilo lwakho njengomngeni wobunjineli odibeneyo-kungekhona umyalelo wemveliso olindele ukuqhutyelwa phambili.
Ndwendwela https://www.tsingtaocnc.com ukufikelela kwithala leencwadi labo lobugcisa: izikhokelo zonyamezelo ezikhutshelwayo kwi-cobalt alloys, iitshathi ezibangela isiphene sengcambu, kunye nesampulu yokulandela umkhondo. Akukho login efunekayo. Akukho ndawo yokuthengisa. Idatha esebenzayo nje-kuba iindawo ezichanekileyo azakhelwanga kwizithembiso. Zakhelwe phezu kokuphindaphindwayo, okuqinisekisiweyo, inkqubo enokuphicothwa.
