Metal jakisoni akamaumba MIM ndondomeko

1. Ndi chiyanikuumba jekeseni wachitsulo?

Metal Injection Molding (MIM)ndi ukadaulo watsopano wapafupi-ukonde kupanga m'munda waufa zitsulo. Njira ya MIM ili ndi masitepe asanu ndi limodzi:Metal Powder Binder-Kukada-Jekeseni Kumangira-Debinding-kuphatikiza ndi kulimbitsa-positi processing.

Ufa:Theufa wachitsulochofunika kwa MIM ali ndi tinthu kakang'ono kwambiri kukula, zambiri mu osiyanasiyana 0 mpaka 30 microns, ndipo amapangidwa ndi apamwamba kwambiri kuthamanga madzi atomization njira kapena mpweya atomization njira;

Mixed powder ndi binder:ufa wachitsulo ndi binder organic zimasakanizidwa kuti zipange tinthu tating'onoting'ono, ndipo tinthu tating'onoting'ono tating'onoting'ono timatenthedwa ndi pulasitiki;

Kuumba jekeseni: The osakaniza ndi extruded mu nkhungu patsekeke kudzera jekeseni akamaumba makina kupanga akhakula gawo;

Kuchotsa mafuta ndi kumanga wothandizira:Binder mu gawo lopanda kanthu amachotsedwa kupyolera mu mankhwala kapena kuwonongeka kwa kutentha kuti apeze gawo lopanda kanthu ndi chitsulo chokha kapena chotsalira chochepa chotsalira;

Kusamalira ndi kuchiza:Tumizani mbalizo mu ng'anjo ya sintering kuti ikhale yolimba kuti mupitirize kuchotsa zotsalira zotsalira;

Pambuyo pokonza:Gwiritsani ntchito kuzimitsa kutentha kutentha, mankhwala kutentha mankhwala, mankhwala nthunzi ndi njira zina kuchepetsa pores mkati mwa gawo, kusintha kachulukidwe gawo, kulimbitsa mphamvu ya gawo, kukana dzimbiri ndi kuvala kukana, etc., kupanga gawo lomaliza.

2. Kodi kuumba jekeseni wachitsulo kuli koyenera pa nthawi ziti?

Panopa,Njira ya MIM imagwiritsidwa ntchito kwambiri pazinthu zamagetsi, mawotchi, zida zazing'ono zamankhwala, mbali za injini zamagalimoto, zida zamasewera, zida zopepuka, ndi zina zambiri.Poyerekeza ndi makina achikhalidwe, ukadaulo wa MIM utha kugwiritsa ntchito bwino zida ndikupanga magawo okhala ndi zovuta. Ndi imodzi mwazothandiza njira zowonjezera ku processing chikhalidwe.

Kukonzekera komwe kumagwiritsidwa ntchito paukadaulo wa MIM kumatha kugawidwa m'mikhalidwe iyi:

1. 1. Mwachizoloŵezi chodula kapena chopera, kutaya kwakuthupi ndi kwakukulu kwambiri, ndipo magawo omwe ali ndi nthawi yayitali yokonza ndi oyenera kuchepetsa ndalama pogwiritsa ntchito luso la MIM.

1. 2. MIM ikhoza kupangidwa mochuluka. Magawo omwe amakwaniritsa zinthu zina zopangira zinthu zambiri koma amakhala ndi kufunikira kochepa poyerekeza ndi mtengo wotsegulira nkhungu ndi oyenera ukadaulo wa MIM.

1. 3. Zitsulo zomwe zimakhala zovuta kudula, monga titaniyamu, nickel alloys, ndi zina zotero, zikhoza kupangidwa kudzera muukadaulo wa MIM. Kulondola kwa mankhwalawa kudzakhala bwino poyerekeza ndi kukonza kwachikhalidwe, ndipo zida zidzapulumutsidwa kwambiri.

1. 4. Zigawo zokhala ndi ma geometries ovuta, monga zigawo zokhala ndi ulusi pamwamba, knurling, njira zopingasa, ndi zina zotero. Zigawo zotere zimakhala zovuta kukwaniritsa muzitsulo zachitsulo. Magawo a Multi-axis kapena ma multi-datum omwe amafunikira kusintha kangapo kwa malo opangirako panthawi yodula. Magawo oyenera kukonzedwa kudzera muukadaulo wa MIM.

1. 5. Zigawo zomwe zimayenera kukonzedwa ndi kuphatikiza kwa zinthu zosiyanasiyana, monga zida zokonzedwa ndi zitsulo ndi zida za ceramic, kapena zida zopangidwa ndi zinthu zosiyanasiyana, monga hard magnetic-soft magnetic, magnetic-non-magnetic, conductive-insulating materials.

3. Ndi zipangizo ziti zomwe zili zoyenera teknoloji yopangira jekeseni yachitsulo?

Mitundu yosiyanasiyana ya zida zomwe zimagwiritsidwa ntchito popanga jekeseni wachitsulo ndizochuluka. M'malo mwake, magawo amatha kupangidwa kudzera mu MIM bola zinthu za ufa zili ndi malo osungunuka pamwamba pa kutentha kwa sintering. Poganizira za chuma, zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapozitsulo zopangidwa ndi chitsulo, nickel-based, ndi low alloys. Carbide, Titaniyamu aloyi, ceramic etc.
