Kunyange zvazvo angangoita ese aruminiyamu alloys ari extrudable mudzidziso, kuongorora extrudability yechimwe chikamu kunoda kufungisisa kwakadzama kwezvinhu zvakaita sezviyero, geometry, alloy type, kushivirira zvinodiwa, scrap rate, extrusion ratio, uye rurimi reshiyo. Pamusoro pezvo, zvakakosha kuti uone kana yakananga kana isina kunanga extrusion ndiyo yakanyanya kukodzera nzira yekuumba.
Yakananga extrusion ndiyo inonyanya kushandiswa maitiro, inoratidzirwa neyakajeka dhizaini uye yakasimba kuchinjika, ichiita kuti ive yakakodzera kune yakafara dhizaini yekugadzira. Nenzira iyi, preheated aluminium billet inosairirwa negondohwe kuburikidza nefa yakamira, uye zvinhu zvinoyerera nenzira imwechete negondohwe. Kukakavadzana pakati pebillet nemudziyo kunowanikwa kune iyi maitiro. Uku kukweshana kunokonzera kupisa kuvakwa uye kuwedzera kushandiswa kwesimba, zvichitungamira mukusiyana kwekushisa uye deformation basa pamwe nehurefu hweextrusion. Nekuda kweizvozvo, misiyano iyi inogona kukanganisa chimiro chezviyo, microstructure, uye dimensional kugadzikana kwechigadzirwa chekupedzisira. Uyezve, sezvo dzvinyiriro ichiita kudzikira mukati menguva yese yeextrusion, zviyero zveprofile zvinogona kusaenderana.
Kusiyana neizvi, indirect extrusion inosanganisira difa rakaiswa pagondohwe reextrusion iro rinoisa kudzvanya kuri mhiri kune stationary aluminium billet, zvichiita kuti zvinhu zviyerere neshure. Nekuti iyo billet inoramba yakamira inoenderana nemudziyo, hapana billet-to-container friction. Izvi zvinoguma nekuwedzera kuwirirana kuumba masimba uye simba rekuisa mukati mekuita. Iyo yunifomu deformation uye mamiriro ekupisa anowanikwa kuburikidza isina kunanga extrusion goho zvigadzirwa zvine yakagadziridzwa dimensional kurongeka, inowirirana microstructure, uye yakagadziridzwa michina zvivakwa. Iyi nzira inonyanya kubatsira kune maapplication anoda kusimba kwakanyanya uye machinability, senge screw machine stock.
Pasinei nemetallurgical mabhenefiti, isina kunanga extrusion ine zvimwe zvisingakwanisi. Chero kusvibiswa kwepamusoro pane billet kunogona kukanganisa zvakananga kupedzwa kwepamusoro kweiyo extrudate, zvichiita kuti zvive zvakakosha kubvisa se-cast surface uye kuchengetedza billet yakachena. Pamusoro pezvo, nekuti iyo inofa inofanirwa kutsigirwa uye kubvumidza iyo extrudate kuti ipfuure, iyo yakanyanya kutenderwa mbiri dhayamita inoderedzwa, ichidzikamisa saizi yeanogona kuwedzeredza maumbirwo.
Nekuda kwekugadzikana kwayo mamiriro ekuita, chimiro chakafanana, uye chepamusoro dimensional kuenderana, isina kunanga extrusion yave nzira yakakosha yekugadzira yakakwira-performance aluminium tsvimbo nemabhawa. Nekudzikisira kusiyanisa kwemaitiro panguva yeextrusion, inowedzera zvakanyanya machinability uye kuvimbika kwekushandisa kwezvakapera zvigadzirwa.
