Inqubo yokukhiqiza yeshidi le-PC iwukubumba i-extrusion, futhi imishini eyinhloko edingekayo i-extruder. Ngenxa yokuthi ukucubungula kwe-PC resin kunzima, izidingo zemishini yokukhiqiza ziphezulu. Imishini eminingi yokukhiqiza yasekhaya yamabhodi e-PC ingenisiwe, iningi layo livela e-Italy, eJalimane naseJapan. Iningi lama-resin asetshenziswayo angeniswa kwa-GE e-USA nase-Baver eJalimane. Ngaphambi kwe-extrusion, impahla kufanele yomiswe ngokuqinile ukuze umswakama wayo ube ngaphansi kuka-0.02% (ingxenyana yobuningi). Imishini ye-extrusion kufanele ifakwe i-vacuum drying hoppers, ngezinye izikhathi eziningana ziyadingeka ochungechungeni. Ukushisa komzimba we-extruder kufanele kulawulwe ku-230-350 ° C, kancane kancane kukhuphuke ukusuka emuva kuya phambili. Ikhanda elisetshenzisiwe yikhanda lohlobo lwe-slit eliyisicaba. I-extrusion bese ipholiswa nge-calendering. Eminyakeni yamuva, ukuze kuhlangatshezwane nezidingo zokusebenza kwebhodi le-PC lokulwa ne-UV, ngokuvamile endaweni yebhodi le-PC embozwe ungqimba oluncane lwezithasiselo ze-anti-UV (UV), okudinga inqubo yokukhishwa kwe-co-extrusion enezingqimba ezimbili, okungukuthi, ungqimba olungaphezulu luqukethe izithasiselo ze-UV futhi ungqimba olungezansi aluqukethe izithasiselo ze-UV. Lezi zingqimba ezimbili zi-laminated ekhanda futhi zikhishwe zibe munye. Lolu hlobo lomklamo wekhanda luyinkimbinkimbi kakhulu. Ezinye izinkampani zithole ubuchwepheshe obusha, njengesistimu ye-Bayer's co-extrusion enepompo encibilikayo eklanywe ngokukhethekile kanye nedivayisi yokuhlanganisa nobunye ubuchwepheshe. Ngaphezu kwalokho, kunezikhathi ezithile ezidinga ukuthi amabhodi e-PC angaconsi, ngakho-ke kufanele kube khona okokulwa nokuconsa kolunye uhlangothi. Kukhona namabhodi e-PC adinga ukuba nongqimba lwe-anti-UV ezinhlangothini zombili, futhi inqubo yokukhiqiza amabhodi anjalo e-PC iyinkimbinkimbi kakhulu.
