Cold extrusion ndi chitsulo akusowekapo ozizira extrusion nkhungu patsekeke, firiji pogwiritsa ntchito kukakamiza akusowekapo pa okhazikika nkhonya osindikizira, pulasitiki mapindikidwe a zitsulo akusoweka Machining njira unakonzedwa mbali.Pakali pano, China watha kutsogolera, malata, zotayidwa, mkuwa, nthaka ndi aloyi ake, otsika mpweya zitsulo, mpweya zitsulo, chida zitsulo, otsika aloyi zitsulo ndi zitsulo zosapanga dzimbiri ndi zina zitsulo ozizira extrusion, ngakhale kubala zitsulo, mkulu mpweya mkulu. Aluminiyamu aloyi chida zitsulo, liwiro zitsulo, etc., angakhalenso kuchuluka kwa mapindikidwe ozizira extrusion.Mu zida extrusion, China ali ndi luso kupanga ndi kupanga milingo matani osindikizira extrusion.Kuwonjezera ntchito makina osindikizira wamba, makina osindikizira hayidiroliki, ozizira extrusion osindikizira, komanso bwinobwino ntchito makina osindikizira mikangano ndi mkulu-liwiro mkulu-mphamvu zida ozizira extrusion.

Extrusion amakakamizika plastically golide fumbi agglomerates kuyenda mwa kusiyana pakati pa nkhonya ndi kufa kapena kufa kubwereketsa, kupanga dzenje mtanda gawo kapena mtanda gawo ang'onoang'ono kuposa ndondomeko akhakula kwa gawo.Ngati kufinya kwaukali popanda kutenthetsa, kumatchedwa ozizira extrusion.Cold extrusion alibe tchipisi, imodzi yaing'ono chip mbali processing luso, chomwechonso golide zidutswa pulasitiki processing luso, njira zapamwamba.Ngati opanda kanthu ndi usavutike mtima ndi kutentha m'munsimu recrystallization kutentha extrusion, amatchedwa ofunda extrusion.Warm Extrusion akadali ndi mwayi wa tchipisi tating'ono.

Kufinya, mu njira yomweyo ndi otaya malangizo a kayendedwe ka nkhonya zitsulo, amene angathe kupangidwa akalumikidzidwa zosiyanasiyana ndi extruded olimba ndi dzenje mbali.

Anti-extrusion, mbali yotsutsana ndi kayendedwe ka nkhonya yachitsulo.Anti-extrusion zosiyanasiyana akalumikidzidwa angapezeke chikho.

Composite extrusion, akusowekapo mbali ya zitsulo otaya malangizo ndi malangizo a kayendedwe ka nkhonya yemweyo, pamene mbali ina ya zitsulo zimayenda molunjika moyang'anizana ndi kayendedwe ka nkhonya.Akhoza kukonzekera ndi coextrusion zosiyanasiyana makapu, ndodo, chubu mbali.

Radial extrusion, kayendedwe ka kayendedwe kazitsulo ndi kayendetsedwe kazitsulo zachitsulo.Extrusion akhoza kugawidwa mu radial centripetal ndi centrifugal extrusion extrusion, extrusion kupanga magiya ozungulira helical, maluwa kiyibodi ndi mbali zina.

Popanga, zitsulo zopanda kanthu zimatuluka kunja.Forging ntchito kupanga mbali kapena flanged shaft flange woboola pakati kapu mbali.
