Makina omangira jekeseni amagwiritsidwa ntchito popanga jekeseni ndi nkhungu yachitsulo, momwe nkhungu inati imakhala ndi ming'oma yomwe ili mu nkhungu yapansi ndi nkhungu yapamwamba, momwe njira imapangidwira pamalo okonzedweratu m'kati mwa nkhungu yapansi pafupi ndi nkhungu. polowera kubaya utomoni wosungunuka (P) m'bowo.Kutsegula kwa ngalandeko kumakutidwa kotheratu, kupanga njira yozizirirapo yozizirirapo kotero kuti sing'anga yozizira (monga mpweya wozizirira) imalowetsedwa munjirayo, imadutsa munjira ndikutuluka munjira.Zomwe zimapangidwira m'munsi ndi zam'mwamba zimapangidwa ndi aluminiyamu kapena aluminiyumu alloy.Malo osankhidwa a patsekeke, omwe amalumikizana mwachindunji ndi utomoni wosungunuka, amapangidwa ndi mchenga kapena amathiridwa ndi mankhwala kuti apange tinthu tating'onoting'ono.
Metal Powder Injection Molding (MIM) ndi njira yatsopano yopangira zitsulo pafupi ndi net-shape yomwe ikuyambitsa jekeseni wamakono wa pulasitiki kukhala zitsulo za ufa.
Metal nkhungu zikuwonetsedwa pansipa:
Njirayi ndi iyi: Poyamba, ufa wolimba ndi binder organic zimasakanizidwa mofanana, ndiyeno jekeseni mu nkhungu pogwiritsa ntchito makina opangira jekeseni pansi pa kutentha kwa pulasitiki (~ 150 ℃), ndiyeno binder yomwe ilibe kanthu imachotsedwa. mankhwala kapena matenthedwe njira kuwola, ndipo potsiriza mankhwala omaliza amapezedwa sintering ndi densification.Njira: zomangira → kusakaniza → kupanga jakisoni → kuchotsa mafuta → sintering → mutatha chithandizo.
Jekeseni nkhungu ndi chida chopangira zinthu zapulasitiki ndipo ndi chitsimikizo cha mawonekedwe awo athunthu ndi miyeso yolondola.Kumangira jekeseni ndi njira yopangira yomwe imagwiritsidwa ntchito popanga magawo ena ovuta.Imatanthawuza makamaka jekeseni wa zinthu zosungunuka kutentha (kuthamanga kwambiri mu nkhungu, pambuyo pozizira ndi kuchiritsa, kupeza chinthu chopangidwa." Makina ojambulira ufa wa Metal ufa wa zitsulo zopangira jekeseni wazitsulo. Zakhala zosiyana.Kuyanika kwa zinthu zopangira madzi - mu hopper - jekeseni - jekeseni wothamanga (wothamanga wotentha) - mankhwala osakaniza.
