Metal Powder Injection Molding Technology (MIM) ndiukadaulo watsopano wopangira zitsulo pafupi ndi ukonde wopangidwa poyambitsa ukadaulo wamakono wopangira jakisoni wa pulasitiki pagawo la zitsulo za ufa.
Chiyambi chaukadaulo
Ukadaulo wopangira jakisoni wa Metal ufa umaphatikiza ukadaulo wosiyanasiyana monga ukadaulo wopangira pulasitiki, chemistry ya polima, ukadaulo wazitsulo wa ufa, ndi sayansi yazinthu zachitsulo. Amagwiritsa ntchito nkhungu pojambulira zosokonekera za nkhungu ndipo mwachangu amapanga mawonekedwe owoneka bwino kwambiri, olondola kwambiri, amitundu itatu kudzera mu sintering. Zigawo zamapangidwe. Choyamba, ufa wolimba ndi organic binder amapindika mofanana, ndipo pambuyo pa granulation, amabayidwa mu nkhungu ndi makina opangira jekeseni mu kutentha ndi pulasitiki (~ 150 ° C) kuti awonongeke, ndiyeno tchalitchicho chimapangidwa ndi kuwonongeka kwa mankhwala kapena kutentha. Chomangiracho chimachotsedwa, ndipo chomaliza chimapezedwa ndi sintering ndi densification.
Njira luso luso osati ubwino wa njira ochiritsira ufa zitsulo monga masitepe ochepa, palibe kapena zochepa kudula, ndi ubwino mkulu zachuma, komanso kugonjetsa zofooka za miyambo ufa zitsulo mankhwala monga zipangizo m`manja, katundu otsika makina, ndi kuvutika kupanga makoma woonda ndi nyumba zovuta. Ndizoyenera kwambiri kupanga zitsulo zazing'ono, zovuta komanso zofunikira zapadera. Ili ndi mawonekedwe olondola kwambiri, mawonekedwe ofanana, magwiridwe antchito abwino komanso mtengo wotsika wopanga.
Njira kuyenda
Njira yoyenda: binder → kusakaniza → jekeseni → kupukuta → sintering → post-processing.
Mineral powder
The tinthu kukula zitsulo ufa ntchito MIM ndondomeko zambiri 0.5 ~ 20μm; Theoretically, ndi bwino particles, ndi yaikulu yeniyeni pamwamba m'dera, kupangitsa kukhala kosavuta kuumba ndi sinter. Njira yachikhalidwe yopangira zitsulo za ufa imagwiritsa ntchito ufa wokulirapo kuposa 40μm.
Zomatira organic
Ntchito ya organic zomatira ndi kumangiriza zitsulo ufa particles kuti osakaniza ndi rheology ndi lubricity pamene kutentha mu mbiya ya jekeseni makina, ndiko kuti, ndi chonyamulira chimene chimayendetsa ufa kuyenda. Choncho, binder amasankhidwa kukhala chonyamulira ufa wonse. Choncho, kusankha kukoka zomata ndiye chinsinsi cha jekeseni yonse ya ufa.
Zofunikira pazomatira organic:
1.Kugwiritsa ntchito zomatira pang'ono kumatha kupanga rheology yabwino ya osakaniza;
2.Palibe chochita, palibe mankhwala opangidwa ndi ufa wachitsulo panthawi yochotsa zomatira;
3.Easy kuchotsa, palibe mpweya wotsalira mu mankhwala.
Kusakaniza
Ufa wachitsulo ndi binder organic zimasakanizidwa pamodzi kuti zipange zida zosiyanasiyana kukhala zosakaniza za jekeseni. Kufanana kwa osakaniza kumakhudza mwachindunji fluidity ake, motero zimakhudza jekeseni akamaumba ndondomeko magawo, komanso kachulukidwe ndi zina katundu wa zinthu zomaliza. Gawo ili la jekeseni akamaumba ndondomeko n'zogwirizana mfundo ndi ndondomeko jekeseni pulasitiki akamaumba, ndi zipangizo zake zinthu ndi chimodzimodzi. Panthawi yopangira jekeseni, zinthu zosakanizika zimatenthedwa mumtsuko wa makina ojambulira muzinthu zapulasitiki zomwe zimakhala ndi rheological properties, ndipo zimayikidwa mu nkhungu pansi pa jekeseni yoyenera kuti ipange chopanda kanthu. Jakisoni wowumbidwa wopanda kanthu uyenera kukhala wofananira pang'ono kuti mankhwalawo achepetse mofanana panthawi ya sintering.
M'zigawo
The organic binder ili mu owumbidwa akusowekapo ayenera kuchotsedwa pamaso sintering. Njira imeneyi imatchedwa kuchotsa. The m'zigawo ndondomeko ayenera kuonetsetsa kuti zomatira pang'onopang'ono kumasulidwa ku mbali zosiyanasiyana za chosoweka pamodzi ting'onoting'ono ngalande pakati pa particles popanda kuchepetsa mphamvu akusowekapo. Mlingo wochotsa zomangira nthawi zambiri umatsata equation ya diffusion. Sintering imatha kufota ndikuchulukitsa porous degreased blank kukhala zinthu zomwe zili ndi kapangidwe kake ndi katundu. Ngakhale kuti ntchito ya mankhwala okhudzana ndi zinthu zambiri ndondomeko pamaso sintering, nthawi zambiri, ndondomeko sintering ali ndi zimakhudza kwambiri kapena wotsimikiza dongosolo metallographic ndi katundu wa mankhwala chomaliza.
Pambuyo pokonza
Kwa magawo omwe ali ndi kukula kolondola kwambiri, kukonzanso koyenera kumafunika. Njirayi ndi yofanana ndi njira yochizira kutentha kwazinthu zachitsulo.
Ubwino wa ndondomeko
MIM amagwiritsa ntchito makhalidwe luso zitsulo ufa sinter mawotchi mbali ndi kachulukidwe mkulu, katundu wabwino makina ndi pamwamba khalidwe; nthawi yomweyo, amagwiritsa ntchito mikhalidwe ya jekeseni pulasitiki akamaumba kupanga mbali ndi akalumikidzidwa zovuta mu zedi ndi efficiently.
1.Zigawo zamagulu okhala ndi zovuta kwambiri zimatha kupangidwa.
Kukonza zitsulo zachikhalidwe kumaphatikizapo kukonza mbale zachitsulo kukhala zinthu mwa kutembenuza, mphero, planing, kugaya, kubowola, kubowola, ndi zina zotero. MIM imagwiritsa ntchito makina ojambulira jekeseni wopanda kanthu kuti atsimikizire kuti zinthuzo zimadzaza ndi nkhungu, motero zimatsimikizira kukwaniritsidwa kwa gawo lovuta kwambiri la gawolo.
2.The mankhwala ali yunifolomu microstructure, kachulukidwe mkulu ndi ntchito zabwino.
Munthawi yanthawi zonse, kachulukidwe wazinthu zopanikizidwa amatha kufikira 85% ya kachulukidwe kamalingaliro; kachulukidwe wazinthu zomwe zidapezedwa ndiukadaulo wa MIM zitha kufika kupitilira 96%.
3.Kupambana kwakukulu, kosavuta kukwaniritsa misa ndi kupanga kwakukulu.
Chikombole chachitsulo chomwe chimagwiritsidwa ntchito muukadaulo wa MIM chimakhala ndi moyo wofanana ndi wa uinjiniya wa jekeseni wa pulasitiki. Chifukwa chogwiritsa ntchito nkhungu zachitsulo, MIM ndiyoyenera kupanga magawo ambiri.
4.Kusiyanasiyana kwazinthu zogwiritsidwa ntchito komanso magawo ogwiritsira ntchito.
MIM ingagwiritse ntchito pafupifupi zipangizo zambiri zachitsulo, ndipo poganizira chuma, zipangizo zazikulu zogwiritsira ntchito zikuphatikizapo chitsulo, nickel-based, low alloy, copper-based, high-speed zitsulo, zitsulo zosapanga dzimbiri, gram valve alloy, cemented carbide, ndi titaniyamu zitsulo.
5.Significantly kusunga zopangira
Nthawi zambiri, kugwiritsa ntchito zitsulo pokonza ndi kupanga zitsulo kumakhala kochepa. MIM imatha kupititsa patsogolo kuchuluka kwa kagwiritsidwe ntchito kazinthu zopangira, zomwe zimangogwiritsidwa ntchito 100%.
6.Njira ya MIM imagwiritsa ntchito ufa wabwino wa micron-level.
Iwo sangakhoze kokha imathandizira sintering shrinkage, kuthandiza kusintha makina zimatha zipangizo, kuwonjezera moyo kutopa kwa zipangizo, komanso kusintha kukana kupsinjika dzimbiri ndi maginito katundu.
Malo ofunsira
Zogulitsa zake zimagwiritsidwa ntchito kwambiri m'mafakitale monga engineering yamagetsi, zida zamankhwala, zida zamaofesi, magalimoto, makina, zida, zida zamasewera, makampani owonera, zida ndi ndege.
1.Makompyuta ndi zida zawo zothandizira: monga zida zosindikizira, maginito cores, mapini owombera, ndi zida zoyendetsera;
