1. Cov Khoom Siv Thauj Khoom: Yas granules yog pub rau hauv lub thoob los ntawm lub hopper. Raws li cov ntsia hlau tig, lawv raug thawb rau pem hauv ntej raws cov ntsia hlau channel. Qhov sib sib zog nqus ntsia hlau channel nyob rau hauv seem pub mis compacts xoob granules, uas ua rau cov khoom ruaj khov ntws.
2. Compression thiab Plasticization: Nyob rau hauv seem compression, cov ntsia hlau channel yuav ntiav, ua rau cov tsis kam ntawm lub taub hau tuag thiab ntxiv compacting cov khoom. Cua sov nyob rau hauv lub thoob, ua ke nrog kev sib txhuam thiab shearing, softens cov yas mus rau hauv lub viscous ntws xeev. Thaum kawg ntawm qhov compression seem, cov khoom yog softened kiag li.
3. Homogenization thiab Extrusion: Cov seem homogenization kom huv si sib tov cov yaj, tswj qhov kub tsis sib xws. Cov ntsia hlau ces extrudes lub yaj ntawm tus tswj tus nqi thiab siab rau hauv lub taub hau tuag. Tom qab tsim los ntawm kev tuag, txias, shaping, thiab traction txiav ua tiav cov txheej txheem, ua rau cov khoom tiav.
