Isitofu sesinyithi sokubumba inkqubo yeMIM

1. Yintoniukubumba inaliti yentsimbi?

Ukubunjwa kwesitofu sesinyithi (MIM)yiteknoloji entsha yokwenza i-net-net kwinkalo yeumgubo wesinyithi. Inkqubo yeMIM ibandakanya amanyathelo amathandathu:Metal Powder Binder-Ukuxova-Isitofu sokubumba-Ukubophelela-ukungenelela kunye nokuqinisa-ukusetyenzwa kweposi.

Ukwenza umgubo:Iumgubo wentsimbiefunekayo kwi-MIM inomlinganiselo omncinci kakhulu we-particle, ngokuqhelekileyo kuluhlu lwe-0 ukuya kwi-30 microns, kwaye iveliswa yindlela ephezulu kakhulu yoxinzelelo lwe-atomization yamanzi okanye indlela ye-atomization yegesi;

Umgubo oxutywe kunye ne-binder:I-powder yensimbi kunye ne-organic binder ixutywe ngokupheleleyo ukwenza amaqhekeza, kwaye i-particle mix particles ifudunyezwa kwimeko yeplastiki;

Ukubumba ukutofa: Umxube ukhutshelwa kumgodi wokungunda ngomatshini wokubumba inaliti ukuze wenze inxalenye erhabaxa;

Ukususa amafutha kunye nokususwa kwe-arhente ebophelelayo:I-binder kwinxalenye engenanto isuswe ngokusebenzisa ikhemikhali okanye ukubola kwe-thermal ukufumana inxalenye engenanto kunye nesinyithi kuphela okanye isixa esincinci se-binder esiseleyo;

Ukuhlamba kunye nokunyanga:Thumela iindawo kwiziko lokutshisa ukuze ziqiniswe ukususa ngakumbi isibophelelo esishiyekileyo;

Emva kokulungiswa:Sebenzisa ukucima unyango lobushushu, unyango lobushushu beekhemikhali, unyango lomphunga kunye nezinye iindlela zokunciphisa i-pores yangaphakathi yecandelo, ukuphucula ukuxinwa kwenxalenye, ukuphucula amandla enxalenye, ukuxhathisa ukubola kunye nokuxhatshazwa kokugqoka, njl., ukwenza inxalenye yokugqibela.

2. Kweziphi iimeko apho ukubunjwa kwenaliti yentsimbi kufanelekile?

Ngoku,Inkqubo ye-MIM isetyenziswa ngokubanzi kwiimveliso zombane, iiwotshi, izixhobo zonyango ezincinci, iinxalenye zenjini yemoto, izixhobo zemidlalo, izixhobo ezilula, njl.Xa kuthelekiswa nokucutshungulwa koomatshini bemveli, itekhnoloji ye-MIM inokusebenzisa ngokufanelekileyo izixhobo kunye nokwenza iinxalenye ezinezakhiwo ezinzima. Yenye yeendlela ezisebenzayo zokongeza kwiprosesa yemveli.

Ukusetyenzwa okusebenzayo kwitekhnoloji yeMIM kungahlelwa kwezi meko zilandelayo:

1. 1. Kwiinkqubo zendabuko zokusika okanye ukugaya, ukulahlekelwa kwezinto eziphathekayo kukhulu kakhulu, kwaye iinxalenye ezinexesha elide lokucutshungulwa zifanelekile ukunciphisa iindleko ngeteknoloji yeMIM.

1. 2. I-MIM inokuveliswa ngobuninzi. Amacandelo ahlangabezana neemeko ezithile zokuvelisa ubuninzi kodwa anemfuno ephantsi ngokumalunga neendleko zokuvula umngundo zifanelekile kwitekhnoloji yeMIM.

1. 3. Iintsimbi ekunzima ukuzisika, ezifana ne-titanium, i-nickel alloys, njl., zingenziwa ngobuchwepheshe beMIM. Ukuchaneka kwemveliso kuya kuphuculwa xa kuthelekiswa nokucutshungulwa kwendabuko, kwaye izinto ziya kugcinwa kakhulu.

1. 4. Amalungu anejiyometri entsonkothileyo, njengeenxalenye ezinemisonto yomphezulu, i-knurling, iitshaneli ezinqamlezayo, njl. Iinxalenye ezininzi ze-axis okanye iinxalenye ezininzi ze-datum ezifuna utshintsho oluninzi lwezikhululo zokucubungula ngexesha lokusika. Amacandelo alungele ukusetyenzwa ngeteknoloji yeMIM.

1. 5. Amalungu adinga ukucutshungulwa ngokudityaniswa kwezinto ezahlukeneyo, njengamacandelo acutshungulwe ngokudityaniswa kwesinyithi kunye nezixhobo ze-ceramic, okanye iinxalenye ezenziwe ngezinto ezahlukeneyo, ezifana nemagnethi enzima-ethambileyo yamagnetic, imagnetic-non-magnetic, i-conductive-insulating-insulating parts.

3. Ziziphi izinto ezifanelekileyo kwiteknoloji yokubumba inaliti yesinyithi?

Uluhlu lwezixhobo ezisebenzayo kwi-injection yensimbi yokubumba ibanzi. Ngokomgaqo, iinxalenye zinokwenziwa nge-MIM ukuba nje umgubo unendawo yokunyibilika ngaphezu kobushushu bokutshisa. Ukuqwalasela uqoqosho, izixhobo ezisetyenziswa ngoku ngokuqhelekileyo ziqukai-iron-based, i-nickel-based, kunye ne-alloys ephantsi. I-Carbide, i-Titanium alloy, i-ceramic njl.
