Kupanga ndondomeko ya MIM

Kuti makasitomala amvetse mozama zaukadaulo wathu wa Metal Injection Molding, tidzakambirana padera za njira iliyonse ya MIM, tiyeni tiyambire kupanga lero.

Ukadaulo wopangira ufa ndi njira yodzaza ufa wosakanizidwa usanakhazikitsidwe m'chibowo chopangidwa, kugwiritsa ntchito kukakamiza kwina kudzera pa makina osindikizira kuti apange chinthu chopangidwa ndi mawonekedwe, kenako ndikuchotsa mankhwalawo pabowo ndi atolankhani.
Kupanga ndi njira yoyambira zitsulo zopangira ufa zomwe kufunikira kwake ndi kwachiwiri kwa sintering.Ndizoletsa kwambiri ndipo zimatsimikizira njira yonse yopangira ufa wazitsulo kuposa njira zina.
1. Kaya njira yopangirayo ndi yololera kapena ayi, zimadalira mwachindunji ngati ingayende bwino.
2. Zimakhudza njira zotsatila (kuphatikizapo njira zothandizira) ndi ubwino wa mankhwala omaliza.
3. Kukhudza kupanga zokha, zokolola ndi zopangira.

Kupanga makina osindikizira
1. Pali mitundu iwiri ya ma die surface mu makina osindikizira:
a) Pakatikati pa nkhungu yoyandama (ambiri mwamakampani athu ali ndi izi)
b) Kukhazikika nkhungu pamwamba
2. Pali mitundu iwiri ya nkhungu yoyandama pamwamba pa makina osindikizira:
a) Malo opangira amakhazikika, ndipo malo opangira amatha kusinthidwa
b) Malo opangira amakhazikika, ndipo malo owonetsera akhoza kusinthidwa
Nthawi zambiri, mtundu wokhazikika wapakati pakufa umatengera matani ang'onoang'ono, ndipo gawo lapakati limayandama pamlingo wokulirapo.

Njira Zitatu Zopangira
1. Gawo lodzaza: kuchokera kumapeto kwa kugwetsa mpaka kumapeto kwa nkhungu yapakatikati ikukwera mpaka pamtunda wapamwamba kwambiri, makina osindikizira amayambira kuchokera ku 270 mpaka madigiri 360;
2. Siteji ya Pressurization: Ndi siteji yomwe ufa umakanizidwa ndikupangidwa m'mimba.Nthawi zambiri pali chapamwamba kufa pressurization ndi pakati kufa pamwamba kutsika (ie m'munsi atolankhani) pressurization, nthawi zina pamakhala pressurization komaliza, ndiko kuti, chapamwamba nkhonya pressurizes kachiwiri pambuyo mapeto a atolankhani, ntchito ngodya atolankhani akuyamba kuchokera pafupifupi 120 madigiri. mpaka madigiri 180;
3. Demolding siteji: Njira imeneyi ndi njira imene mankhwala ejected kuchokera nkhungu patsekeke.Kugwira ntchito kwa makina osindikizira kumayambira pa madigiri 180 ndipo kumathera pa madigiri 270.

Kachulukidwe kachulukidwe wa ufa compacts

1. Kuponderezedwa kwa njira imodzi

Panthawi yokakamiza, nkhungu yachikazi sichisuntha, nkhonya yapansi yakufa (nkhonya yapamwamba) sisuntha, ndipo kukanikiza kumangogwiritsidwa ntchito ku thupi la ufa kupyolera mu nkhonya yakufa (yotsika nkhonya).
a) Kachulukidwe kachulukidwe kosiyana;
b) Malo osalowerera ndale: kumapeto kwa compact;
c) Pamene H, H / D ikuwonjezeka, kusiyana kwa kachulukidwe kumawonjezeka;
d) Mapangidwe osavuta a nkhungu ndi zokolola zambiri;
e) Oyenera ma compact okhala ndi kutalika kochepa komanso makulidwe akulu akulu

2. Kuponderezedwa kwa njira ziwiri
Panthawi yokakamiza, nkhungu yachikazi sichisuntha, ndipo nkhonya zapamwamba ndi zapansi zimakhala ndi mphamvu pa ufa.
a) Ndilofanana ndi kuponderezedwa kwa njira ziwiri;
b) Shaft yosalowerera ndale siili kumapeto kwa compact;
c) Pansi pa kukakamiza komweko, kusiyana kwa kachulukidwe ndikocheperako kuposa kukanikiza kwapadziko lonse;
d) Angagwiritsidwe ntchito kukanikiza ndi zazikulu H/D compacts
