1. txheej txheem ntws
Extrude roj hmab
Extruding roj hmab yog ib txoj kev ua uas siv cov extruder los extrude cov roj hmab sib tov mus rau hauv ib tug nruam sawb nrog ib tug tshwj xeeb cross-sectional duab. Cov txheej txheem no suav nrog cov kauj ruam hauv qab no:
Mixing: Sib tov roj hmab raw cov ntaub ntawv nrog additives los tsim ib tug roj hmab sib tov.
Pub: Pub cov roj hmab sib tov rau hauv qhov chaw pub noj ntawm lub extruder.
Cov cua sov: cua sov cov roj hmab sib tov los ntawm lub tshuab cua sov kom nws cov yas.
Extrusion: Extrude cov rhuab roj hmab sib tov los ntawm cov neeg kho tshuab lub taub hau los tsim ib tug nruam roj hmab nrog rau qhov xav tau cross-sectional duab.
Moulded Roj Hmab
Moulded roj hmab yog ib txoj kev ua uas yuav tsum tau muab cov roj hmab sib tov rau hauv pwm thiab shaping nws los ntawm lub siab thiab kub. Cov kauj ruam tseem ceeb suav nrog:
Npaj pwm: Tsim thiab npaj pwm nrog cov duab uas xav tau.
Mixing: Sib tov roj hmab raw cov ntaub ntawv nrog additives los tsim ib tug roj hmab sib tov.
Filling pwm: Sau cov roj hmab sib tov rau hauv pwm.
Cua sov thiab siab: Siv cov cua sov thiab siab kom ntws cov roj hmab sib tov thiab sau cov pwm, ua tiav cov txheej txheem molding.
Txias: Txias cov roj hmab hauv cov pwm kom khov rau hauv cov duab uas xav tau.
