Zithunzi za MIM
Zida zopangira jekeseni wachitsulo
Ndondomeko ya MIM ikugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zitsulo zotsika, zitsulo zosapanga dzimbiri, zitsulo zachitsulo, faifi tambala aloyi, tungsten aloyi, aloyi olimba, titaniyamu aloyi, maginito zipangizo, Kovar aloyi, ziwiya zadothi zabwino, etc.
Ndizitsulo ziti zomwe zili zoyenera panjira ya MIM:
1. Kulemera kwa zigawo za MIM nthawi zambiri kumakhala 0.2g - 200g.
2. Malo omwe akuyembekezeredwa ndi 100 square centimeters.
3. Kukula kwa magawo a MIM kupitirira 10MM ndi ± 0.5%.
4. The MIM mbali pazipita khoma makulidwe ndi 10MM.
5. Kukula kochepa 0.2MM.

Kumangira zitsulo zachitsulo ndikwatsopanoufa zitsulo ndondomeko, imatha kutulutsa kachulukidwe kwambiri komanso mawonekedwe ovutazigawo za sinteredpopanda makina. Ndi mawonekedwe apadera a zida za MIM, MIM imatha kupanga zida zachitsulo zolondola pazinthu zosiyanasiyana, kuphatikiza magalimoto, mafoni am'manja, zida zamanja, zida zamano, zida za pneumatic, zida zamagetsi zamagetsi, zida zopangira opaleshoni, katundu wamasewera ndi makompyuta apakompyuta. Zida zachitsulo zomwe zimagwiritsidwa ntchito kwambiri mu njira ya MIM ndi chitsulo chosapanga dzimbiri, chitsulo cha alloy ndi zida zofewa za maginito.
