Umgaqo-siseko we-MIM wokudibanisa-A

1. Inkcazo yokubumba

Gxininisa ipowder kwi-compacts eluhlaza kunye nesimo esithile, ubukhulu, i-porosity kunye namandla, inkqubo yi-MIM eyenza.

2. Ukubaluleka kokubumba

I-1) Yinkqubo yesiseko somgubo we-metallurgy okubaluleka kwayo okwesibini kuphela kwi-sintering.
I-2) Ikhawulela ngakumbi kwaye imisela yonke inkqubo yokuvelisa i-powder metallurgy kunezinye iinkqubo.
a) Ukuba indlela yokuyila ifanelekile okanye ayikho imisela ngokuthe ngqo ukuba ingaqhuba kakuhle na.
b) Ukuchaphazela iinkqubo ezilandelayo (kubandakanywa iinkqubo ezincedisayo) kunye nomgangatho wemveliso yokugqibela.
c) Ukuchaphazela imveliso ezenzekelayo, imveliso kunye neendleko zemveliso.

Ukubumba ukunyanzeliswakukulayisha umgubo wesinyithi okanye umxube we-powder kwi-mold press press (i-female mold), cinezela i-powder ngokusebenzisa i-punch ye-die, kwaye emva kokuba uxinzelelo lukhululiwe, i-compact ikhutshwe kwi-mold ye-female ukugqiba inkqubo yokubumba.

Imisebenzi ephambili yoxinzelelo lokubumba yile:

1. Yenza umgubo ube yimo efunekayo;
2. Nika i-compact kunye nemilinganiselo yejometri echanekileyo;
3. Nika i-porosity efunekayo kunye nemodeli ye-pore kwi-compact;
4. Nika ii-compacts amandla afanelekileyo ukuze kube lula ukuphatha.

Iziganeko ezenzeka ngexesha lokuxutywa komgubo:

1. Emva kokucinezela, i-porosity ye-powder body iyancitshiswa, kwaye ubuninzi be-compact compact buphezulu kakhulu kunomzimba we powder.
Ukunyanzeliswa kunciphisa ukuphakama kwe-stacking yomgubo, ngokubanzi ukuxinwa kudlula i-50%

2. Uxinzelelo lwe-Axial (uxinzelelo oluhle) lusetyenziswa kumzimba we powder.Umzimba ongumgubo uziphatha njengolwelo ukuya kumlinganiselo othile.Xa i-force isetyenziswe kudonga lokubumba lobufazi, i-reaction force-lateral pressure iyenziwa.

3. Njengoko i-powder idibene, ukuxinwa kwe-compact kwandisa, kwaye amandla e-compact nawo ayanda.

4. Ngenxa yokuxhatshazwa phakathi kweengqungquthela zepowder, ukuhanjiswa koxinzelelo akulingani, kwaye ukuxinwa kwamacandelo ahlukeneyo kwi-compact ayilingani.Ubuninzi obungalinganiyo be-compact eluhlaza bunempembelelo ebaluleke kakhulu ekusebenzeni kwe-compact eluhlaza kunye nemveliso.

5. Emva kokuba uxinzelelo lukhululiwe kwaye ludilizwe, ubukhulu be-compact eluhlaza buya kwandisa-ukuvelisa i-elastic after-effect.I-Elastic aftereffect sesinye sezizathu eziphambili zokuguqulwa kunye nokuqhekeka kwe-compact.
