Chii chinonzi powder metallurgy tekinoroji?

Powder metallurgy tekinoroji yakatanga kushandiswa muUnited States muna 1870. Yakashandisa hupfu hwesimbi sechinhu chakabikwa, ndokutsimbirira copper-lead alloy mabearings kuti ione tekinoroji yekuzvizora yekutakura, uye yakagadzira zvikamu zvakasiyana-siyana nezvikamu kuburikidza nekutsikirira. uye kuimba.Iyo poda metallurgy tekinoroji nzira inonzwika isingazivikanwe kune wese munhu, asi kana mushure mekutsanangura kwangu, zvichava nyore kwauri kuti unzwisise.

Iyo yakakosha maitiro ehupfu metallurgy tekinoroji
Nyaya huru ipfu yakaisvonaka yesimbi, ipapo poda inowedzerwa kune inodiwa mold, uye ipapo muenzaniso unoumbwa ne (jekiseni) kana kumanikidzika, uye pakupedzisira chikamu chinodiwa uye mhedzisiro inogona kuwanikwa ne sintering.Zvimwe zvikamu zvinoda post-processing.

Ndeupi musiyano weMIM uye PM poda metallurgy zvikamu?
1: Powder metallurgy injection molding
Powder metallurgy jekiseni molding akaberekerwa muCalifornia muna 1973, inonzi MIM.Irwo rudzi rutsva rwepoda metallurgy molding tekinoroji yakagadzirwa nekubatanidza epurasitiki jekiseni rekugadzira tekinoroji nemunda wepoda metallurgy.Iyo poda metallurgy jekiseni kuumba maitiro iri padyo neupfu simbi tekinoroji.Kutanga, hupfu hwakasimba uye organic binder zvakasanganiswa zvakafanana, uye zvino zvinopisa uye zvepurasitiki pakupisa kukuru kwe150 degrees.Iyo jekiseni yekuumba midziyo inoshandiswa kupinza mold mugomba, uye wobva waomesa uye kuumbwa.Iyo nzira yekuora inobvisa binder mune yakaumbwa isina chinhu, uye pakupedzisira, seupfu simbi, zvikamu zvehunyanzvi zvinogadzirwa kuburikidza nekunyungudika.

2: Powder metallurgy kudzvanya
Powder metallurgy compression molding ndeyekuzadza mold nehupfu negiravhiti, uye kuiburitsa nekumanikidza kwemuchina.Iyo ndeimwe yeanonyanya kushandiswa mune inoshanda maindasitiri maapplication.Cold-yakavharwa simbi mold kudzvanya, inotonhora isostatic kudzvanya, inopisa isostatic kudzvanya, uye inodziya kudzvanya zvese zvinogadzira.Nekudaro, nekuti inogona chete kudzvanywa kumusoro nekudzika mumativi ese, mamwe maumbirwo akaomarara haagone kugadzirwa kana anogona kungoitwa ma blanks.

Zvikamu zvakawanda zvinoshandisa jekiseni kuumba kana compression molding, uye chikamu chekupedzisira kuita kuchave kwakasiyana.Kana uchiri kutadza kusiyanisa zvakanaka, usazeze kutibata isu Jingshi New Materials kuti tibvunze.
