Extrusioninzira yekugadzira zvigadzirwa zvirefu zveanogara achiyambuka-chikamu (tsvimbo, mashiti, mapaipi, mafirimu, waya yekuvharisa coating) kumanikidza kupfava.polymerkubudikidza nefa rine buri.
Polymer zvinhu muchimiro chepellets inodyiswa mune extruder kuburikidza hopper.Izvo zvinhu zvinozoendeswa kumberi nechikuro chekudyisa uye kumanikidzwa kuburikidza nekufa, kuchinjika kune inoenderera polymer chigadzirwa.
Zvinhu zvinopisa, zvakaiswa pamusoro pedhiramu, zvinyorove uye zvinyunguduse iyo polymer.Kupisa kwezvinhu zvinotungamirirwa ne thermocouples.
Chigadzirwa chinobuda kunze chinotonhodzwa nemhepo inofefetwa kana mumvura yekugezesa.
Extrusion yema polymers(kusiyana neextrusion yesimbi) inoramba ichienderera kwenguva yakareba sekunge mapeteti mbishi achipihwa.
