Nzira yekufananidza pakati pekushanda kwemukati sleeve ye extrusion barrel uye mold inofanira kusarudzwa maererano nekugadzirwa kwealuminium alloy products.Pane yakachinjika extruder, nzira mbiri dzekufananidza dzinowanzo shandiswa: nzira yekuisa chisimbiso yakatsetseka, ndiko kuti, yekuisa chisimbiso pakati peiyo silinda yeextrusion uye kumagumo kumeso kwefa iri munzira yekubata ndege.Zvakanakira ndezvokuti zviri nyore kugadzirisa, zviri nyore kushanda, iyo unit inomanikidza pamagumo eforoma uye iyo yemukati lining idiki, uye hazvisi nyore kupwanywa uye kuremara.Izvo zvakashata ndezvekuti kuiswa chisimbiso kwakashata.Kana simba rekusimbisa risina kukwana, kana nzvimbo yekubata isina kuenzana, simbi yakaremara inopfachukira zviri nyore kubva pakubata kumeso kuita "chivharo chikuru".
Edza kuchengetedza tambo ye extrusion cylinder yakasimba, kana kushandisa gasket kuchenesa jira munguva.Kana iyo extrusion chishandiso chakanyatso kupfekwa kana paine tsvina mubhushi reextrusion cylinder, iyo yemukati liner haina kucheneswa nepedhi yekuchenesa nenguva, uye haina kutsiviwa nenguva, inokonzeresa shrinkage (pakupera kweimwe. Extrusion products, mushure mekuderera Kuongorora kaviri, pane nyanga-yakafanana chiitiko pakati pechikamu chemuchinjikwa, iyo inonzi shrinking).
Kana iyo yemukati lining ye extrusion cylinder yakapfekwa zvakanyanya, mold haigone kusimbiswa zvakasimba, zvichikonzera eccentricity, izvo zvinokonzeresa kusaenzana kwemadziro ukobvu hweiyo extruded profile.
