Txhawm rau ua tiav cov khoom siv lub cev ntawm txhuas rods, nws yog ib qho tsim nyog kom ua tiav cov khoom siv lub cev ntawm cov hlau: xaiv qhov tsim nyog aluminium alloy thiab nws hom, xaiv qhov tsim nyog quenching (txias) txoj kev, siv qhov tsim nyog aging kub thiab tswj lub sij hawm laus. Yield Yield yog lwm qhov tseem ceeb hauv kev tsim khoom. Qhov taw qhia tseem ceeb: 100% tawm los yog theoretically tsis yooj yim sua kom ua tiav vim hais tias lub extrusion txiav lub taub hau (Butts) thiab cov khoom txiav tawm vim lub clamping cim ntawm lub tsheb laij teb thiab lub tshuab ncab yog inevitable.
Ntxiv nrog rau cov khoom seem, bruises, kuaj ua ntej, pwm hloov cov tshuab kuaj, thiab lwm yam uas tshwm sim thaum lub sij hawm txhuas bar extrusion, cov txiaj ntsig dav dav tuaj yeem ncav cuag li 85%. Cov nroj tsuag extrusion hauv Suav teb feem ntau tsuas yog ncav cuag 70% - 75% tawm los.
Aluminium pas nrig ntau lawm efficiency. Cov txiaj ntsig tseem ceeb ntawm kev siv extrusion muaj xws li: Extrusion xovxwm siv tus nqi: qhov sib piv ntawm qhov tseeb tso zis ntawm extrusion xovxwm rau lub peev xwm tsim, extrusion xovxwm tawm los, per capita tso zis ib chav tsev lub sij hawm, sab hauv seem tus nqi, rov qab tus nqi, Number. thiab lub sijhawm downtime.
