Umatshini wokubumba wenaliti usetyenziselwa ukubumba ngokubumba ngesinyithi, apho ukungunda kuthe kukho umngxuma obandakanya umngxuma wokungunda ongezantsi kunye nokungunda okuphezulu, apho umjelo wenziwa kwindawo emiselwe kwangaphambili kumngxuma wokungunda ongezantsi indawo yokutofa intlaka etyhidiweyo (P) emngxunyeni.Ukuvuleka kwemijelo kugutyungelwe ngokupheleleyo, okwenza umjelo wokupholisa ophakathi ukuze indawo yokupholisa (umz. umoya opholileyo) ifakwe kwindawo yokungena, iqukuqele kwimijelo kwaye ikhutshwe kwindawo yokuphuma.Iimbumba ezisezantsi neziphezulu zenziwe nge-aluminiyam okanye i-aluminium alloy.Iindawo ezikhethiweyo zombhobho, ezidibana ngokuthe ngqo ne-resin etyhidiweyo, zixutywe ngesanti okanye ziphathwe ngamakhemikhali ukuze zenze ama-bumps amancinci.
I-Metal Powder Injection Molding (MIM) bubuchwephesha obutsha besinyithi somgubo obukufutshane ne-net-shape technology obuzisa ukubumba inaliti yeplastiki yanamhlanje ibe yisinyithi somgubo.
Ukungunda kwesinyithi kuboniswe ngezantsi:
Inkqubo imi ngolu hlobo lulandelayo: Ekuqaleni, umgubo oqinileyo kunye nesibophelelo sezinto eziphilayo zixutywa ngokufanayo, ze emva koko zitofwe kumgodi wokungunda ngomatshini wokubumba ngenaliti phantsi kwemeko eshushu yeplastiki (~ 150 ℃), emva koko isibophelelo kwisithuba esingenanto sisuswa Ikhemikhali okanye indlela yokubola kwe-thermal, kwaye ekugqibeleni imveliso yokugqibela ifunyenwe nge-sintering kunye noxinaniso.Inkqubo: isibophelelo → ukuxuba → ukwenza isitofu → ukukhupha igrisi → sintering → emva konyango.
Isitofu sokungunda sisixhobo sokwenziwa kweemveliso zeplastiki kwaye sisiqinisekiso sesakhiwo sabo esipheleleyo kunye nemilinganiselo echanekileyo.Isitofu sokubumba yindlela yokucubungula esetyenziswa kwimveliso yobuninzi yamacandelo athile anzima.Ibhekisa ngokukodwa ekutofweni kwezinto ezinyibilikiswe bubushushu (ngoxinzelelo oluphezulu kumgodi wokungunda, emva kokupholisa nokuphiliswa, ukufumana imveliso eyenziweyo. Ukusetyenziswa komatshini wenaliti yomgubo wesinyithi wesixhobo sokubumba ubuchwephesha benaliti yomgubo. Inkqubo yokudibanisa i-process binder yomiswa - kwi-hopper - isitofu sokubumba - imbaleki ebandayo (imbaleki eshushu) - unyango oluluhlaza.
