(1) Cov khoom siv hlau txeem tuaj yeem tau txais qhov kev siv zog ntau tshaj li qhov sib txawv thiab kev tsis tsim nyob rau hauv lub cheeb tsam deformation dua ntawm lub nruas forging, uas tuaj yeem siv lub koob meej ntawm cov hlau kom tiav.
(2) Extrusion tsis tuaj yeem tsim tau cov rods, cov hlua, profiles, thiab hlau zoo li cov khoom ua haujlwm uas yooj yim cross-section nrhiav, tab sis kuj tsim cov ntawv sau thiab cov hlua khiab ntawm cov duab khej.
(3) Extrusion moulding yooj, tsuas xav hloov cov cuab yeej extrusion xws li molds, muaj peev xwm tsim cov khoom ntawm ntau daim thiab ntau yam ntawm ib qho khoom, kev khiav hauj lwm ntawm kev hloov lub extrusion tuag yog yooj yim, ceev, lub sij hawm txuag thiab npaum.
(4) Lub precuding ntawm cov khoom extruded yog siab, qhov zoo ntawm qhov khoom zoo zoo, thiab kev siv tus nqi thiab cov paib ntawm cov khoom hlau kuj zoo tuaj.
(5) Cov txheej txheem extrusion muaj kev cuam tshuam zoo heev rau cov khoom siv dag zog ntawm cov hlau.
(6) Ib tus tswvcuab tus tswvcuab tshwj xeeb tshaj li qhov uas muaj qhov sibluag los yog sib sau ua ke yuav tau txais los ntawm ib qho kev rho tawm.
