(1) Txhim kho tus deformability ntawm cov ntaub ntawv raw. Cov khoom siv hlau yog nyob rau hauv ib qho kev muaj zog rau peb lub hauv paus uas muaj kev nyuab siab nyob rau hauv cheeb tsam lub plaster, thiab cov khoom muaj peev xwm ua tau kom muaj peev xwm loj heev.
(2) Cov zoo ntawm cov khoom muaj siab. Extrusion yuav ua kom cov qauv ntawm cov ntaub ntawv raw thiab txhim kho nws cov khoom siv dag zog. Cov longitudinal mechanical cov khoom ntawm cov khoom extruded tom qab quenching thiab kev laus muaj ntau dua lwm txoj kev. Piv nrog dov, forging thiab cov zoo li, cov extruded khoom muaj siab dimensional thiab zoo nto zoo.
(3) Zoo kawg nkaus. Extrusion muaj zoo yooj. Nws tuaj yeem hloov pauv, qhov loj thiab ntau yam rau tib yam khoom los ntawm hloov pwm. Cov hloov ntawm cov pwm yooj yim, yooj yim, lub sijhawm-siv thiab ua haujlwm.
(4) Tus txheej txheem yog qhov yooj yim thiab cov cuab yeej tsawg. Piv rau cov yeeb nkab thiab cov ntaub ntawv profile xws li tho thiab dov, thiab dhau-dov, extrusion muaj qhov zoo ntawm cov txheej txheem luv luv.
