Piula kila extruded welahoʻohana ʻia i ka hana ʻana i ke kaʻina extrusion wela e hana i nā paipu kila seamless.

Hoʻohana nui ʻia ka extrusion wela i ka hana ʻana o ka aluminika, ke keleawe a me nā paipu metala nonferrous ʻē aʻe.ʻO ka extrusion wela o ke kila no ka hana ʻana i nā paipu kūikawā a me nā profiles, paʻakikī ke hoʻohana no ka hana ʻana i ka extrusion anu a i ʻole extrusion o ke kikowaena paʻa a me ka mahana o ka lua (ma o ka puka a i ʻole ka puka makapō) ke kila kila a me nā ʻāpana kila. e like me ke koʻokoʻo me ka mānoanoa poʻo, barela, ipu, etc. Hot extrusion o ka dimensional pololei a me ka ili hoʻopau 'oi aʻe ma mua o wela forging 'āpana, akā naʻe pono e hele me ka hapa o ka laulā hoʻopau a machining.

Hot extrusion 'enehana he 'ano o ka metala ma luna o ka recrystallization mahana o extrusion, ka paipu billet mai ka make extrusion, i mea e loaa make shape kea pauku paipu metala hana 'ano.I ka wela extrusion kaʻina (mai ka paipu i arakawa tube), ka paipu billet he deformation ma lalo o ekolu i compressive stress moku'āina.ʻAʻole hiki i kēia ke hoʻoponopono wale i ka pilikia o ka hoʻoheheʻe ʻia ʻana o ka paipu kila liʻiliʻi, akā hiki ke pale aku i nā paipu i loko a i waho o nā hemahema o ka ʻili i hoʻokumu ʻia e ke koʻikoʻi tensile.No laila, kūpono loa ke ʻano hana hoʻoheheʻe wela no nā ʻano kila kila a pau, kuhili
