I-cold extrusion iyinsimbi engenalutho endaweni ebandayo yesikhunta se-extrusion, ekamelweni lokushisa ngokufaka ingcindezi ku-blank on a fixed punch press, deformation yepulasitiki ye-metal blank machining method yalungiswa izingxenye.Njengamanje, i-China isikwazile ukuhola, ithini, i-aluminium, ithusi, i-zinc kanye nama-alloys ayo, insimbi ephansi ye-carbon steel, i-carbon steel, insimbi yamathuluzi, insimbi ephansi ye-alloy nensimbi engagqwali kanye nezinye i-extrusion yensimbi ebandayo, ngisho nokuthwala insimbi, i-carbon high insimbi yensimbi ye-aluminium alloy, insimbi enesivinini esikhulu, njll., ingase futhi ibe inani elithile lokuguqulwa kwe-extrusion ebandayo.Emishinini ye-extrusion, iShayina inamandla okuklama nokwenza imishini yokunyathelisa ye-tonnage extrusion.Ngaphezu kokusebenzisa imishini yokunyathelisa evamile, imishini yokunyathelisa ye-hydraulic, i-extrusion presses ebandayo, kodwa futhi isetshenziswe ngempumelelo imishini yokunyathelisa ye-friction kanye nemishini ye-high-speed high-energy for extrusion ebandayo.

I-Extrusion iphoqeleka ukuba ama-agglomerate othuli lwegolide ageleze ngegebe phakathi kwe-punch kanye ne-die noma i-outlet yokufa, ukwakhiwa kwesigaba esiphambanayo esingenalutho noma ingxenye encane encane kunenqubo enzima yengxenye.Uma ukukhama okumahhadlahhadla ngaphandle kokuwushisisa, kubizwa ngokuthi yi-cold extrusion.I-Cold extrusion ayinawo ama-chips, ubuchwepheshe obuncane bokucubungula izingxenye ze-chip, kunjalo nobuchwepheshe bokucubungula ipulasitiki yegolide, indlela ethuthukisiwe.Uma okungenalutho kushisiswe ekushiseni okungaphansi kwe-extrusion ye-recrystallization lokushisa, kubizwa ngokuthi i-extrusion efudumele.I-Warm Extrusion isenayo inzuzo yama-chips angekho ngaphansi.

Ukucindezela, ohlangothini olufanayo kanye nesiqondiso sokugeleza kokunyakaza kwe-punch yensimbi, okungakhiqizwa ngezindlela ezihlukahlukene kukhishwe izingxenye eziqinile nezingenalutho.

I-Anti-extrusion, isiqondiso esiphambene nesiqondiso sokugeleza kwe-punch yensimbi.Anti-extrusion of bobunjwa ehlukahlukene ingatholakala inkomishi.

I-extrusion eyinhlanganisela, ingxenye engenalutho yesiqondiso sokugeleza kwensimbi kanye nesiqondiso sokunyakaza kwe-punch efanayo, kuyilapho enye ingxenye yensimbi igeleza ibheke ohlangothini oluphambene nokuqondisa kokunyakaza kwe-punch.Kungenziwa uzilungiselele by coextrusion of the ezihlukahlukene izinkomishi, izinduku, tube izingxenye.

I-Radial extrusion, isiqondiso sokugeleza kanye nesiqondiso sokunyakaza kwe-punch yensimbi perpendicular.I-Extrusion ingahlukaniswa ibe yi-radial centripetal kanye ne-centrifugal extrusion extrusion, i-extrusion yokwenza amagiya e-radial helical, amakhibhodi ezimbali nezinye izingxenye.

Lapho kukhiwa, insimbi engenalutho igeleza ibheke ngaphandle.I-Forging esetshenziswa ekwenzeni izingxenye noma izingxenye ezimise okwenkomishi shaft flange.
