2.Technical Overview
Metal Ente Molding (MIM):
- Tlhaloso: MIM ke mokhoa oa ho etsa lihlahisoa o kopanyang phofo ea tšepe le polymer binder ho etsa lijo. Sehlahisoa sena sa phepelo se kenngoa ka har'a hlobo, se etsa sebopeho se lakatsehang. Karolo e bōpiloeng e kena ts'ebetsong ea ho kopanya ho tlosa binder, e lateloa ke sintering ho finyella ts'ebetso e feletseng ea tšepe.
- Mehato ea Ts'ebetso:
- Tokisetso ea Feedstock: Ho kopanya phofo ea tšepe le se tlamang ho etsa lijo tse nang le homogeneous feedstock.
- Ho Bopa ka Ente: Lijo tsa lijo li kenngoa ka har'a hlobo tlas'a khatello e phahameng le mocheso ho theha "karolo e tala."
- Debinding: The binder e tlosoa, ho theha karolo ea tšepe e nang le porous.
- Sintering: Karolo ea porous e futhumetse mocheso o ka tlase ho ntlha ea ho qhibiliha, e leng se etsang hore likaroloana tsa tšepe li kopane le ho teteana, e leng se hlahisang karolo ea tšepe e teteaneng ka ho feletseng.
