Kana mainjiniya achida yakakwirira-chaiyo simbi zvikamu zvinoshingirira 30,000 psi hydraulic pressure, kuramba galling mudzimba pombi yemvura yemunyu, kana kuchengetedza dimensional kugadzikana mushure me800°C kupisa kwekupisa-standard machining or die casting kazhinji inodonha. Apa ndipo pane chokwadi simbi jekiseni kuumba muitiro fekitari inowana nzvimbo yayo: kwete semutengesi wegeneric, asi semubatsiri wehunyanzvi ane ruzivo mufizikisi yeakatsetseka-grained microstructures, binder burnout kinetics, uye sintering shrinkage muripo.
Isu takaona vatengi vachitumira maMIM prototypes ane ± 0.3% mutsara kushivirira-kungoona panguva yekuyedzwa kwekushanda kuti cobalt alloy nozzles yakamonyoroka pasi pekumhanyisa bhasikoro. Chikonzero chikuru? Kusadzora kwakaringana pa debinding ramp rates uye sintering atmosphere dova point. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mijenya yega yega yeMIM inotanga neAMS 5387 kana T800 poda yakawanda certification-kwete chete tensile data, asi okisijeni zvirimo, particle size distribution (D50 ≤ 8.2 µm), uye tap density verification. Isu tinoramba mabhechi kunze kwe4.2–4.4 g/cm³. Uku hakusi kunyanyisa. Ndiwo mabatiro atinoita ± 0.05 mm pa 12-mm-diameter piston pombi silinda yedzimba mabhore mushure mekunyungudika.
Mafekitari mazhinji anobata MIM se "hupfu + mold + moto." Isu tinozvitora sezvitatu zvakabatanidzwa chirango: rheology-inodzorwa feedstock kuumbwa, chaiyo mold dhizaini dhizaini yakarongedzerwa anisotropic shrinkage, uye mhepo-inodzorwa sintering ine chaiyo-nguva okisijeni partial pressure monitoring. Semuenzaniso, yedu cobalt-nickel alloy plugs inoda mbiri-nhanho sintering mbiri: 60 maminetsi pa1150 ° C mu5% H₂-95% N₂ kubvisa yakasara kabhoni, ipapo 90 maminetsi pa1320 ° C mune yakachena hydrogen kuti iwane> 99.2% density. Svetuka chero nhanho, uye kuoma kunodonha kubva pa42 HRC kuenda pa36 HRC-zvakakwana kuita kuti nguva isati yakwana ipfeke muzvigaro zvevharuvhu yakakwirira. Isu tinonyora ese parameter. Batch yega yega inotakura kuteedzera kuzere: poda yakawanda, binder mujenya, mold cavity ID, sintering choto nzvimbo, uye CMM yekuongorora rondedzero.
Vertical integration inotiparadzanisa kubva kumabroker. Isu hatisi outsource sintering. Isu hatisi kurima kunze kwekupedzisira machining. Yedu ISO-inoenderana nzvimbo inomhanyisa MIM padivi peshanu-axis CNC machining, kuisa mari, uye vacuum kupisa kurapwa-zvese pasi pedenga rimwe. Kana mutengi achitumira dhirowa yeGD&T yechikamu chepombi cheAMS 5387 chine mapombi echokwadi pamaburi masere Ø3.2 mm ane hukama neØ25 mm datum, isu hatikumbiri kujekeswa. Isu tinotevedzera nzira yeturusi-induced kutsaudzira, kugadzirisa post-sintering kukanganisa tichishandisa ekare shrinkage mepu, uye kushandisa chiedza chekupedza-kutendeuka chete apo pakakosha chisimbiso panoda Ra ≤ 0.4 µm. Hapana rework. Hapana zvinoshamisa. Chekutanga-pass kutevedzera.
Real-world delivery inotsamira pane zvinoitika pamberi pekutanga kupfura. Takaongorora pamusoro pe1,200 MIM-yakagadzirira dhizaini kubva 2020-uye takawana matatu anodzokororwa mapoinzi ekutadza: undercuts inoda EDM sink electrode pachinzvimbo cheyakajairwa mold simbi, madziro ukobvu shanduko inodarika 3: 1 chiyero (zvichikonzera shrinkage) uye maburi mapofu akadzika kupfuura 4 × dhayamita (trapping binder). Chikwata chedu cheinjiniya chinoratidzira izvi mu pre-kugadzirwa ongororo-yemahara-uye inokurudzira geometry tweaks iyo inoderedza mutengo ne22% paavhareji. Mumwe mutengi wemidziyo yemafuta ekuNorth America akadzikisa nguva yekutungamira kubva pamavhiki gumi nemana kusvika pamavhiki matanhatu neshanu mushure mekutora yedu DFM mhinduro loop.
Kana chikumbiro chako chichida kudzokororwa mumayuniti zviuru zvishanu, kuenderana kwesimbi mumabhechi makumi maviri, kana kusimbiswa kwekushanda kupfuura ASTM B962, unoda zvinopfuura fekitori yesimbi jekiseni rekuumba. Unoda mumwe wako anobata magiramu ese ecobalt alloy senge calibrated instrumentation-uye anoyera kubudirira kwete mumabhokisi akatumirwa, asi mu zero kukundikana kwemunda mushure me10,000 maawa ekushanda. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inovaka chokwadi ichocho mudanho rega rega rekuita. Kwete sedzidziso. Sekuita kwezuva nezuva.
