Njira yopanga pepala la PC ndi kuumba kwa extrusion, ndipo zida zazikulu zomwe zimafunikira ndi extruder. Chifukwa kukonza kwa utomoni wa PC ndikovuta, zofunikira pazida zopangira ndizokwera. Zida zambiri zopangira ma PC board zimatumizidwa kunja, zomwe zambiri zimachokera ku Italy, Germany ndi Japan. Ma resin ambiri omwe amagwiritsidwa ntchito amatumizidwa kuchokera ku GE ku USA ndi Baver ku Germany. Asanatuluke, zinthuzo ziyenera kuuma mwamphamvu kuti chinyezi chake chikhale pansi pa 0.02% (kagawo kakang'ono). Zida za extrusion ziyenera kukhala ndi ma vacuum drying hoppers, nthawi zina zingapo zimafunikira mndandanda. Kutentha kwa thupi la extruder kuyenera kuyendetsedwa pa 230-350 ° C, pang'onopang'ono kuwonjezeka kuchokera kumbuyo kupita kutsogolo. Mutu ntchito ndi lathyathyathya extruded anatumbula mtundu mutu. The extrusion ndiye utakhazikika ndi calendering. M'zaka zaposachedwapa, pofuna kukwaniritsa zofunika za PC gulu odana UV ntchito, nthawi zambiri pa bolodi PC pamwamba yokutidwa ndi woonda wosanjikiza odana UV (UV) zina, amene amafuna awiri wosanjikiza co-extrusion ndondomeko, ndiko kuti, pamwamba pake imakhala ndi zowonjezera za UV ndipo pansi ilibe zowonjezera za UV. Zigawo ziwirizi ndi laminated m'mutu ndi kutulutsa m'modzi. Mtundu uwu wa mapangidwe amutu ndi ovuta kwambiri. Makampani ena atengera umisiri wina watsopano, monga Bayer's co-extrusion system yokhala ndi pampu yosungunuka yopangidwa mwapadera ndi chipangizo chophatikiza ndi matekinoloje ena. Kuphatikiza apo, pali nthawi zina zomwe zimafuna kuti ma board a PC asakhale opanda dontho, kotero payenera kukhala zokutira zotsutsana ndi kudontha mbali inayo. Palinso ma PC board omwe amafunika kukhala ndi anti-UV wosanjikiza mbali zonse ziwiri, ndipo kupanga ma PC board ndi ovuta kwambiri.
