Raws li kev xav tau tshwj xeeb ntawm cov neeg siv khoom, peb tuaj yeem muab 2-txheej / 3-txheej / 5-txheej thiab multilayer khoom phab ntsa yeeb nkab kab. Ntau lub extruders tuaj yeem ua ke, thiab ntau lub ntsuas qhov hnyav tuaj yeem xaiv tau. tuaj yeem ua haujlwm hauv nruab nrab tswj hauv lub ntsiab PLC kom ua tiav qhov tseeb thiab ntau yam ntawm txhua tus extruder. Raws li ntau txheej kauv pwm tsim nrog cov txheej txheem sib txawv thiab cov tuab tuab, kev faib cov pwm kab noj hniavraws yog tsim nyog los xyuas kom meej tias lub raj txheej thickness yog uniform thiab cov nyhuv plasticization ntawm txhua txheej yog zoo dua.
