Ɔl tu di MIM ɛn PIM de yuz injɛkshɔn moldin mashin dɛn fɔ fos matirial insay wan mold kaviti ɔnda ay prɛshɔn. Di matirial, ilɛksɛf na mɛtal fidstɔk ɔ plastic pɛlɛt, dɛn kin wam am te i rich wan stet we dɔn rɔtin ɛn afta dat dɛn kin put am insay di mol. Di mold kin mek di matirial kol kwik kwik wan, ɛn dis kin mek i strɔng ɛn tek di shep we di say we di bɔdi de gɛt.

Difrɛns pan di post-prɔsɛsin .
Di ki difrɛns bitwin MIM ɛn PIM de na di post-prɔsɛsin stɛp dɛn. Insay PIM, wans di pat dɔn kɔmɔt na di mol, i essentially kɔmplit. I kin nid sɔm smɔl smɔl trim ɔ finish, bɔt di matirial prɔpati dɛn dɔn ɔlrɛdi establish. Bɔt MIM nid tu ɔda step dɛn afta dɛn dɔn mol:
Debinding : Dis involv fɔ pul di binder matirial frɔm di pat we dɛn dɔn mol, lɛf biɛn wan porous mɛtal strɔkchɔ.
Sintering : Dɛn kin ɔt di pat we dɛn dɔn dibayn to wan ay tɛmpracha, we kin mek di mɛtal patikyula dɛn kin fuz togɛda ɛn densify, we kin mek dɛn gɛt strɔng, sɔlid kɔmpɔnɛnt.
Dɛn ɛkstra stɛp ya de mek MIM bi mɔ kɔmpleks ɛn tɛm-kɔnsum prɔses pas PIM, bɔt dɛn impɔtant fɔ ajɔst di matirial prɔpati dɛn we dɛn want ɛn dimɛnshɔnal akkuracy.
