Kev tsim kho tshuab extrusion yog qhov kev lag luam tshuab uas muab los rau kev tsim kho tshuab plastic nrog daim duab sib npaug hauv txhua lub sijhawm. Nws sib koom nrog ib qhov chav tshuab tshwj tsis uas ua haujlwm tib si thaum muaj kev coj cai nyob hauv zos. Kev tsim kho pib nrog kev tshuab thiab sau tshuab polymer resin, feem ntau siv cov dej saum toj kom tshem tawm cov dej uas tuaj yeem tsim tau cov nqaij. Lub tshuab tom qab ntawv rov mus rau hauv tshuab extruder, thaum twg nws raug hlau, sib puag ncig, thiab muab ntxuav nrog qhov ntxuav. Lub thawj hlau uas muaj zos raug sau tshuab los ntawm qhov chaw tshuab tshwj tsis uas tsim tau qhov chaw tshuab tseemceeb. Lub teb chaws thiaj li tshwm sim yog qhov tseemceeb: lub thawj hlau kub thiab yooj yooj raug sau tshuab los ntawm qhov chaw tshuab calibration uas siv qhov ntxuav, qhov ntxuav, thiab kev sov kom dhau qhov chaw tshuab tseemceeb thiab qhov loj. Tom qab ntawv nws tig mus rau hauv qhov chaw tshuab sov kom sov tas li. Qhov caterpillar haul-off muab qhov tshuab tshwv dav, thiab qhov siab ntawm nws yuav tsum sib cuag zoo nrog qhov tshuab extruder kom tso tseg kev tshuab lossis kev tshuab. Lub tshuab tom qab ntawv yog qhov sawv cev los ntawm qhov chaw tshuab sau lossis qhov chaw tshuab coiling, xws li qhov sawv cev lossis qhov chaw tshuab spooling, uas muab tshuab tshuab. Qhov kev sib txawv ntawm qhov tshuab extrusion nyob rau hauv qhov kev tshuab automation thiab kev coj cai, nrog rau cov sensors thiab computers uas coj cai cov ntsiab lus tseemceeb xws li teperature, pressure, thiab dimensions kom paub meej tias muaj kev tshuab zoo tshaj plaws thiab tsawg kev tshuab.
