Inkqubo yokuvelisa iphepha le-PC kukubumba i-extrusion, kunye nezixhobo eziphambili ezifunekayo yi-extruder. Ngenxa yokuba ukusetyenzwa kwe-PC resin kunzima, iimfuno zezixhobo zokuvelisa ziphezulu. Uninzi lwezixhobo zemveliso yasekhaya yeebhodi zePC zingeniswa ngaphandle, uninzi lwazo zivela eItali, eJamani naseJapan. Uninzi lweeresin ezisetyenzisiweyo zithunyelwa kwi-GE e-USA naseBaver eJamani. Ngaphambi kwe-extrusion, izinto eziphathekayo kufuneka zomiswe ngokungqongqo ukwenzela ukuba umswakama wayo ube ngaphantsi kwe-0.02% (iqhekeza lobuninzi). Izixhobo zokukhupha kufuneka zixhotyiswe nge-vacuum drying hoppers, ngamanye amaxesha ezininzi ziyafuneka kuthotho. Ukushisa komzimba we-extruder kufuneka kulawulwe kwi-230-350 ° C, ngokunyuka ngokuthe ngcembe ukusuka ngasemva ukuya phambili. Intloko esetyenzisiweyo yintloko yohlobo lwe-slit ethe tyaba. I-extrusion ke ipholiswe nge-calendering. Kwiminyaka yakutshanje, ukuze kuhlangatyezwane neemfuno zebhodi yePC yokusebenza kwe-anti-UV, ngokufuthi kumphezulu webhodi yePC egqunywe ngocweyo olucekethekileyo lwezongezo ezichasene ne-UV (UV), ezifuna inkqubo yoqhagamshelwano lwamaleko amabini, oko kukuthi, umaleko womphezulu uqulethe izongezo ze-UV kwaye umaleko ongezantsi awunazo izongezo ze-UV. Ezi maleko zimbini zine-laminated entloko kwaye zikhutshelwe kwenye. Olu hlobo loyilo lwentloko lunzima ngakumbi. Ezinye iinkampani zamkele itekhnoloji entsha, njengenkqubo ye-Bayer's co-extrusion enempompo enyibilikayo eyilelwe ngokukodwa kunye nesixhobo sokudibanisa kunye nobunye ubugcisa. Ukongeza, kukho amaxesha afuna ukuba iibhodi zePC zingathontsi, ngoko ke kufuneka kubekho i-anti-drip coating kwelinye icala. Kukho neebhodi zePC ezifuna ukuba ne-anti-UV umaleko kumacala omabini, kwaye inkqubo yokuvelisa iibhodi zePC ezinjalo inzima kakhulu.
