Cold extrusion ke tšepe sekoa ka a batang extrusion hlobo hlobo cavity, ka mocheso kamoreng ka ho sebelisa khatello ea ho se nang letho ka e tsitsitseng litebele tsa khatiso, polasetiki deformation ea tšepe se nang letho machining mokhoa ne ho lokiselitsoe likarolo.Hona joale, China e khonne ho etella pele, thini, aluminium, koporo, zinki le lisebelisoa tsa eona, tšepe e tlaase ea carbon, carbon steel, sesebelisoa sa tšepe, tšepe e tlaase ea alloy le tšepe e sa hloekang le tse ling tsa tšepe tse batang, esita le ho jara tšepe, k'habone e phahameng. aluminium alloy tool steel, high speed steel, joalo-joalo, e ka boela ea e-ba palo e itseng ea deformation ea extrusion e batang.Lisebelisoa tsa extrusion, China e na le bokhoni ba ho rala le ho etsa mechine ea khatiso ea extrusion ea maemo a tonnage.Ntle le ho sebelisa mechine e tloaelehileng ea khatiso, mechine ea hydraulic presses, e batang ea extrusion presses, empa hape e atlehile ho sebelisa mechine ea ho ferekanngoa le lisebelisoa tse phahameng tsa matla a matla bakeng sa extrusion e batang.

Extrusion e qobelloa plastically khauta lerōle agglomerates phallang ka lekhalo pakeng tsa punch le die kapa die outlet, tlhahiso ea sekoti sefapano karolo kapa sefapano karolo e nyenyane ho feta tshebetso kaba bakeng sa karolo.Haeba e petetsa ka thata ntle le ho e futhumatsa, e bitsoa cold extrusion.Cold extrusion ha e na lichifi, theknoloji e le 'ngoe e nyane e sebetsanang le likarolo tsa chip, ho joalo le ka theknoloji ea ho lokisa polasetiki ea khauta, mokhoa o tsoetseng pele.Haeba sekheo se futhumetse ho mocheso o ka tlase ho mocheso oa mocheso oa recrystallization, o bitsoa extrusion e futhumetseng.Mofuthu Extrusion e ntse e na le monyetla oa ho se be le li-chips tse nyane.

Ho penya, ka tataiso e tšoanang le tataiso ea phallo ea motsamao oa tšepe ea tšepe, e ka hlahisoang ka libopeho tse fapaneng li entsoe ka likarolo tse tiileng le tse sekoti.

Anti-extrusion, tsela e fapaneng le tataiso ea phallo ea punch ea tšepe.Anti-extrusion ea libopeho tse sa tšoaneng e ka fumanoa senoelo.

Composite extrusion, karolo e se nang letho ea tataiso ea phallo ea tšepe le tataiso ea motsamao oa punch e tšoanang, ha karolo e 'ngoe ea tšepe e phalla ka tsela e fapaneng le tataiso ea motsamao oa punch.E ka lokisoa ka coextrusion ea linoelo tse fapaneng, melamu, likarolo tsa tube.

Radial extrusion, tataiso ea phallo le tataiso ea motsamao oa tšepe oa tšepe perpendicular.Extrusion e ka aroloa ka radial centripetal le centrifugal extrusion extrusion, extrusion ho etsa radial helical gears, lipalesa keyboards le likarolo tse ling.

Ha ho etsoa, ​​​​tšepe e se nang letho e phalla ka ntle.Forging e sebelisoang ha ho etsoa likarolo kapa likarolo tse bōpehileng joaloka komiki ea flanged shaft.
