1. Lub extrusion chim ntawm aluminium extrusion tshuab yuav tsum muaj peev xwm txav tau. Txhawm rau kom ntseeg tau tias cov khoom siv tau zoo thaum lub sijhawm rov qab extrusion, stroke ntawm extrusion chim yuav tsum me ntsis loj dua qhov ntev ntawm extrusion chim. Yog li ntawd, tsis yog txhua tus extruder yog tsim rau thim rov qab extrusion.
2. Lub sijhawm sib txawv ntawm kev thim rov qab extrusion yog qhov ntev, yog li nws yog qhov nyuaj rau kev tswj xyuas qhov zoo ntawm cov khoom siv aluminium thaum lub sij hawm rov qab extrusion, thiab qhov zoo ntawm cov ntaub ntawv aluminium extruded yog tsawg.
3. Kev ua haujlwm ntawm kev thim rov qab extrusion tshuab yog qhov nyuaj dua, thiab lub sijhawm sib txawv yog ntev dua li ntawm kev xa mus rau extrusion. Lub voj voog extrusion feem ntau ntev dua li ntawm kev xa mus rau pem hauv ntej. Txawm li cas los xij, vim tias qhov loj thiab qhov zoo ntawm cov ingot tuaj yeem nce ntxiv, qhov seem ntawm qhov poob siab me me, thiab cov extrusion ceev yog siab, qhov nce hauv lub sijhawm pabcuam yog them rau qee yam, ua rau rov qab extrusion ntau dua.
4. Qhov siab tshaj plaws circumscribed lub voj voog txoj kab uas hla ntawm extruded txhuas yog txwv los ntawm lub zog ntawm hollow extruded pas nrig
