Iigiya ngamalungu angundoqo othutho lwezandla. Ngokuqhelekileyo, iigiya ziphantsi koxinzelelo lwempembelelo ngexesha le-meshing, kunye neencopho zoxinzelelo ezibekwe kufutshane nomphezulu wegiya. Ke ngoko, iigiya zifuna amandla aphezulu kunye nokumelana nokunxiba okuphezulu kwindawo okanye kufutshane nomphezulu. Ijometri yegiya engachanekanga okanye amacandelo anokunciphisa ubomi begiya kunye nomthamo womthwalo, kunye nokwandisa ingxolo. Ke ngoko, iimfuno zomgangatho wezixhobo zothumelo ziphezulu kakhulu, zihlala ziphezulu kune-DIN7. Ukongeza kwiimfuno zamandla kunye nengxolo, iimfuno zokuphucula uqoqosho kunye nokusebenza nazo zongezwa. Imithwalo yegiya luxinzelelo oluphezulu kwindawo okanye kufuphi nomphezulu, ngoko ke ukuxinana okupheleleyo kwenxalenye yonke akufuneki. Uxinaniso olukhethiweyo lomphezulu lufanelekile kule meko yokulayisha, inkqubo inokwenza umaleko oxineneyo kumphezulu wenxalenye, i-porosity yomphezulu isondele kwi-zero, kwaye i-porosity engundoqo ijikeleze i-10%. Kwiminyaka yakutshanje, i-PMG iphuhlise inkqubo ye-DensiForm, ethi inyuse ngokukhethekayo ingxinano yomphezulu wegiya e-sintered ngelixa igcina i-porosity ye-core, ivumela ukwakheka komgangatho oxineneyo ngokupheleleyo kubunzulu be-0.5-1mm. Iveliswe yinkqubo yesinyithi somgubo, ukusebenza kwegiya kusetyenziswa ngokupheleleyo kuthumelo lwangoku.
Amalungu emodyuli yolungelelwaniso yothumelo lwencwadi zizinto zophuhliso lweiindawo zesinyithi somguboishishini. Kule minyaka imbalwa izayo, la macandelo aya kuba negalelo ekukhuleni okukhawulezayo koshishino lwamalungu esinyithi somgubo. Kwiminyaka yakutshanje, iipropathi ezipheleleyo kunye nomphezulu we-powder metallurgy steel kunye nezixhobo zokusebenza ziphuculwe. , le nkqubela phambili iphunyezwa ngokusetyenziswa kwezixhobo zokuvelisa eziphambili kunye neenkqubo, ezifana neziko ezinokusebenzisa i-sinter Cr-alloyed steel okanye inkqubo yeDensiForm ekhethiweyo yoxinaniso. Ukuvunywa kwentshaamacandelo metallurgy umgubo, kubandakanywa imikhono yokutyibilika kunye neegiya zomthwalo, ivula imarike yezicelo ezintsha zeenkqubo zetsimbi yesinyithi ekuhanjisweni.
