Amashumi alithoba epesenti yamalungu achanekileyo emoto enziwa ngomgubo wesinyithi.Inkqubo ye-metallurgy yomgubo iquka iteknoloji yokwenza i-PM press kunye ne-MIM yokubumba iteknoloji yokubumba.Iigiya zeemoto, iibheringi zeemoto, iinxalenye ze-automotive tailgate, kunye neendawo zokucima i-automotive ngokusisiseko zicinezelekile nge-PM Ukuvelisa iteknoloji.

Inqaku Ⅰ: iimpembelelo zokubumba ushicilelo

Ukubaluleka kwesikhunta kwi-teknoloji yokwenza i-press kuyabonakala.Kucetyiswa ukuba usebenzise i-mold female okanye i-mandrel eyenziwe nge-samente ye-carbide, i-powdered high-speed steel kunye nezinye izinto.I-mold isebenza kunye ne-surface roughness incinci kangangoko kunokwenzeka ukunciphisa iinqununu ze powder kunye ne-mold I-friction factor phakathi kweendonga.

I-Factor Ⅱ: impembelelo ye-lubricant

Ukongeza i-lubricant kwi-metal exutywe ngumgubo kunokunciphisa ngokufanelekileyo ukungqubana phakathi komgubo kunye naphakathi komgubo kunye nodonga lokubumba, kwaye wenze ukusabalalisa kobuninzi be-compact ngaphezulu ngokufanayo.I-lubricant esetyenziswa ngokuqhelekileyo yi-zinc fatty acid.Nangona inokuphucula iimeko zokwenza i-press, ngenxa yobuninzi bayo obuphantsi, ulwahlulo lulula ukwenzeka emva kokuxuba, kwaye iindawo ezixubileyo zixhomekeke kwi-pitting kunye nezinye iingxaki.

Umba Ⅲ: Iimpembelelo zoxinzelelo lweeparamitha

1: Isantya soxinzelelo

Ukuba isantya esicinezelayo sikhawuleza kakhulu, siya kuchaphazela ukufana kwe-compact compact density eluhlaza kwaye kuya kubangela ukuqhekeka.Kungcono ukusebenzisa umatshini wokwenza umgubo wehydraulic ukuwuvelisa.

I-2: Ukubamba ixesha loxinzelelo

Ngaphantsi koxinzelelo oluphezulu loxinzelelo kunye nokubamba uxinzelelo lwexesha elifanelekileyo, ukuxinana kwe-compact ye-powder metallurgy ecinezela iinxalenye zemoto kunokunyuswa kakhulu.

I-3: Ubume beebhuthi zokutyisa umgubo

Ukuba i-powder feeding shoe yendalo yonke isetyenziselwa ukugcwalisa umgubo, ukuzaliswa kwepowder engalinganiyo kuya kwenzeka phezulu nangaphantsi okanye ngaphambi nangemva komgodi, oya kuchaphazela umgangatho we-compact.Ukuphucula okanye ukuhlaziya isicathulo sokutya umgubo kunokuphucula ukufana kokuzaliswa komgubo.
