Cov txheej txheem yas extrusion molding ua los ntawm cov yas extruder feem ntau muaj peb theem: raw khoom plasticization, shaping, thiab txias. Yas extruders yog categorized rau ntau hom; cov uas nruab nrog cov ntsia hlau tau muab cais ua ib qho - ntsia hlau, ntxaib- ntsia hlau, lossis ntau- ntsia hlau extruders, thiab lwm yam. Tsis tas li ntawd, raws li lawv txoj haujlwm ua haujlwm, extruders tuaj yeem muab faib ua ntu ntu thiab ntu. Lub peev xwm tso zis ntawm extruder feem ntau txiav txim siab los ntawm kev sib hloov ceev ntawm nws cov ntsia hlau. Cov ntsia hlau ceev tsis tsuas cuam tshuam lub ntim ntawm cov yas extruded tab sis kuj tseem cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm cov txheej txheem plasticization.
Kev saws me nyuam ntawm kev tsim khoom rau cov yas extruders ua rau cov tuam txhab ua kom haum rau cov kev cai tshwj xeeb thiab tshwj xeeb ntawm cov neeg siv ntau haiv neeg, yog li ua kom luv luv ntawm kev tshawb fawb thiab kev loj hlob mus rau cov khoom tshiab thiab pab txhawb kev ntes ntawm cov lag luam loj. Ib yam li ntawd, cov tswv yim tsim khoom tshwj xeeb tso cai rau kev tsim cov khoom siv tawm sab nraud- lossis txawm tias kev yuav khoom thoob ntiaj teb - ntawm ntau qhov system modules thiab cov khoom uas xav tau rau cov khoom siv extrusion molding. Txoj hauv kev no ua pov thawj muaj txiaj ntsig zoo rau kev ua kom tag nrho cov khoom zoo, txo cov nqi tsim khoom, thiab ua kom cov peev nyiaj nrawm dua.
