Cold extrusion mea he metala hakahaka i ke anu extrusion mold lua, ma ka lumi wela ma ka noi ana i ke kaomi i ka blank ma ka paʻa punch kaomi, plastic deformation o ke metala blank machining kaʻina hana i hoʻomākaukau 'āpana.I kēia manawa, ua hiki iā Kina ke alakaʻi, tin, aluminika, keleawe, zinc a me kāna mau mea hoʻohui, haʻahaʻa kalapona kila, kalapona kila, mea hana kila, haʻahaʻa haʻahaʻa kila a me nā kila kila a me nā mea hoʻoheheʻe anuanu ʻē aʻe. alumini alumini kila kila, kiʻekiʻe wikiwiki kila, etc., hiki no hoi i kekahi nui o ka deformation o ke anu extrusion.I loko o nā lako extrusion, hiki iā Kina ke hoʻolālā a hana i nā mīkini paʻi kiʻekiʻe tonnage.Ma waho aʻe o ka hoʻohana ʻana i nā mīkini mīkini maʻamau, nā kaomi hydraulic, nā kaomi extrusion anu, akā ua hoʻohana maikaʻi ʻia nā kaomi friction a me nā mea hana kiʻekiʻe kiʻekiʻe no ka extrusion anu.

Extrusion ua koi plastically gula lepo agglomerates kahe ma waena o ke kuʻi a me ka make aiʻole ka make puka, ka hana 'ana o ka hollow kea pauku a i ole kea pauku liʻiliʻi ma mua o ka paʻakikī kaʻina no ka hapa.Inā ʻomi ʻia ka ʻōpala me ka ʻole o ka wela, ua kapa ʻia ʻo cold extrusion.ʻAʻohe o nā ʻāpana ʻāpana liʻiliʻi i ka extrusion, hoʻokahi ʻenehana hana ʻāpana ʻāpana liʻiliʻi, pēlā pū ka ʻenehana hoʻoheheʻe ʻili gula, kahi ala holomua.Inā wela ka blank i kahi mahana ma lalo o ka extrusion wela o ka recrystallization, ua kapa ʻia ka extrusion mahana.Loaʻa i ka Warm Extrusion ka maikaʻi o nā ʻāpana liʻiliʻi.

ʻO ke kaomi ʻana, ma ka ʻaoʻao hoʻokahi a me ke ala kahe o ka neʻe ʻana o ka punch metala, hiki ke hana ʻia i nā ʻano like ʻole i extruded paʻa a me nā ʻāpana.

Anti-extrusion, ka ʻaoʻao ʻē aʻe o ke ala kahe o ka punch metala.Hiki ke loaʻa ke kīʻaha anti-extrusion o nā ʻano like ʻole.

Composite extrusion, blank hapa o ka metala kahe kuhikuhi a me ke kuhikuhi o ka neʻeʻana o ka like punch, a me ka 'ē aʻe o ka metala kahe ma ke ala kū'ē i ke kuhikuhi o ka neʻe o ka punch.Hiki ke hoʻomākaukau ʻia e ka coextrusion o nā kīʻaha like ʻole, nā koʻokoʻo, nā ʻāpana paipu.

Radial extrusion, kahe ala a me ke kuhikuhi o ka metala punch neʻe perpendicular.Hiki ke hoʻokaʻawale ʻia ka Extrusion i ka radial centripetal a me ka extrusion extrusion extrusion, extrusion e hana i nā radial helical gears, nā kīʻaha pua a me nā ʻāpana ʻē aʻe.

I ka hana ʻana, e kahe ana ka metala i waho.Hoʻohana ʻia ka forging i ka hana ʻana i nā ʻāpana a i ʻole flanged shaft flange ʻāpana kīʻaha kīʻaha.
