Amagiya ayizingxenye ezibalulekile zesakhiwo sikagesi oshintshwayo. Imvamisa, amagiya angaphansi kwengcindezi yomfutho ngesikhathi sokuhlangana, ngeziqongo zengcindezi ezitholakala eduze kwendawo yegiya. Ngakho-ke, amagiya ikakhulukazi adinga amandla aphezulu kanye nokumelana nokugqokwa okuphezulu endaweni noma eduze kwayo. Ijiyomethri yegiya engalungile noma izingxenye zinganciphisa impilo yegiya nomthamo wokulayisha, futhi kwenyuse umsindo. Ngakho-ke, izidingo zekhwalithi zamagiya okudlulisela ngokuvamile ziphezulu kakhulu, ngokuvamile ziphakeme kune-DIN7. Ngaphezu kwezidingo zamandla nomsindo, izidingo zokuthuthukisa umnotho nokusebenza nazo zengezwa. Imithwalo yamagiya izingcindezi eziphezulu endaweni noma eduze kwayo, ngakho-ke ukuminyana okugcwele kwayo yonke ingxenye akudingekile. Ukuminyana kwendawo okukhethiwe kusilungele lesi simo sokulayisha, inqubo ingenza ungqimba oluminyene phezu kwengxenye, i-porosity yangaphezulu isondele ku-zero, kanti i-core porosity ngokuvamile iba ngu-10%. Eminyakeni yamuva nje, i-PMG ithuthukise inqubo ye-DensiForm, ekhetha ngokukhetha ukuminyana kobuso begiya le-sintered ngenkathi igcina i-porosity yomnyombo, okuvumela ukwakheka kongqimba lwangaphezulu oluminyene ngokuphelele ekujuleni kuka-0.5-1mm. Ikhiqizwe inqubo ye-powder metallurgy, ukusebenza kwegiya kusetshenziswa ngokugcwele ekudluliselweni kwamanje.
Izingxenye zemojula yokuvumelanisa yokuhambisa ngesandla ziyizinto zokuthuthukiswa kweizingxenye ze-powder metallurgyimboni. Eminyakeni embalwa ezayo, lezi zingxenye zizofaka isandla ekukhuleni ngokushesha kwemboni yezingxenye ze-powder metallurgy. Eminyakeni yamuva, izakhiwo eziphelele nezingaphezulu zensimbi ye-powder metallurgy kanye nezinto zokusebenza ziye zathuthukiswa. , lokhu kuthuthuka kufinyelelwa ngokusetshenziswa kwezinto ezithuthukisiwe zokukhiqiza nezinqubo, njengezithando zomlilo ezingafaka insimbi ye-Cr-alloyed noma inqubo ekhethiwe ye-DensiForm yokuhlanganisa. Ukugunyazwa okushaizingxenye ze-powder metallurgy, okuhlanganisa imikhono eshelelayo namagiya okulayisha, kuvula imakethe yezinhlelo zokusebenza ezintsha zezinqubo ze-powder metallurgy ekudluliseni.
