I-Extrusionkuyinqubo yokukhiqiza imikhiqizo emide ye-cross-section engaguquki (izinduku, amashidi, amapayipi, amafilimu, i-wire insulation coating) ukuphoqa ukuthambisai-polymerngefa elinesimbobo.
Izinto ze-polymer ngendlela yama-pellets zifakwa ku-extruder nge-hopper.Izinto ezisetshenziswayo zibe sezidluliswa phambili ngesikulufu sokuphakelayo futhi ziphoqelelwe ngedayizi, ziguqulelwa kumkhiqizo we-polymer oqhubekayo.
Izakhi zokushisa, ezibekwe phezu komgqomo, zithambe futhi zincibilike i-polymer.Ukushisa kwezinto ezibonakalayo kulawulwa yi-thermocouples.
Umkhiqizo ophuma edayizini upholiswa ngomoya oshaywayo noma okugeza ngamanzi.
Ukukhishwa kwama-polymers(ngokungafani nokukhishwa kwezinsimbi) inqubo eqhubekayo ehlala njalo inqobo nje uma ama-pellets aluhlaza ehlinzekwa.
I-Extrusion isetshenziselwa ikakhulukaziI-Thermoplastics,kodwaAma-elastomersfuthiAma-thermosetsnazo zingase zikhishwe.Esimweni esinjaloukuxhumanisaamafomu ngesikhathi sokushisa nokuncibilika kwezinto ku-extruder.
Imikhiqizo ye-thermoplastic extruded ingase iphinde yakhiwe yi-I-Thermoformingindlela.
