Ufa zitsulo(PM) ndi mawu ofotokoza njira zosiyanasiyana zomwe zida kapena zigawo zake zimapangidwa kuchokera ku ufa wachitsulo.Njira za PM zimatha kupewa, kapena kuchepetsa kwambiri, kufunikira kogwiritsa ntchito njira zochotsera zitsulo, potero kuchepetsa kutayika kwa zokolola popanga ndipo nthawi zambiri kumabweretsa mtengo wotsika.

Amagwiritsidwa ntchito kwambiri m'makampani opanga zida zamitundu yambiri ndipo padziko lonse lapansi ~ 50,000 tonnes/chaka (t/y) amapangidwa ndi PM.Zogulitsa zina ndi monga zosefera sintered, porous mafuta-impregnated bearings, magetsi kukhudzana ndi zida diamondi.

Chiyambireni kupanga mafakitale-scale metal powder-based additivemanufacturing (AM) m'zaka za m'ma 2010, kusankha laser sintering ndi njira zina zazitsulo za AM ndi gulu latsopano la ntchito zogulitsa zitsulo za ufa.

The powder metallurgy press and sinter process zambiri zimakhala ndi masitepe atatu: ufa blending (pulverization), die compaction, and sintering.Compaction nthawi zambiri imachitika pa kutentha kwa chipinda, ndipo kutentha kwapamwamba kwa sintering nthawi zambiri kumachitika molingana ndi mlengalenga komanso moyendetsedwa bwino ndi mpweya.Kukonzekera kwachiwiri kosankha monga kupangira ndalama kapena kutenthetsa nthawi zambiri kumatsatira kuti mupeze zinthu zapadera kapena kuwongolera bwino (kuchokera ku WIKIPEDIA)
