Gawo loyamba la kusakaniza ndikuwongolera zomwe zili muzitsulo zonse ndi kutentha kwa kuphika, kotero kuti kuuma ndi zosakaniza zikhale zokhazikika.Pambuyo kusakaniza, chifukwa colloid ikadali ndi zonyansa ndipo si yunifolomu, iyenera kusefedwa.Kuphatikiza pa kuonetsetsa kuti colloid ilibe zonyansa, fyulutayo iyeneranso kuonetsetsa kuti mphira wa rabara ukhoza kutsindika mofanana panthawi ya ntchito.Gawo la kupanga ma roller a rabara ndi kusefa ndikofunikira makamaka pamakina osindikizira othamanga kwambiri, kuti apewe kukulitsa kapena kutsika komwe kumachitika chifukwa chazifukwa zosiyanasiyana.
Kenako mphira wa rabara wa mafakitale amatenthedwa, kukakamizidwa ndi kutenthedwa kuti akhazikitse pulasitiki, kotero kuti pamene mphira umachepa panthawi yogwiritsira ntchito, shrinkage ikhoza kuchepetsedwa kukhala yochepa.Njira yochiritsira imatha kupangitsa kuti ikhale yofewa komanso yolimba popanda kutaya kufewa kwake, ndipo pamapeto pake imatha kusamutsa inkiyo.
Chomaliza ndi kupera ndi kupukuta.Osasowa kutentha kosalekeza kwa masitepe awiriwa.Apo ayi, kutentha kumakhala kotsika kwambiri, n'kosavuta kukhala brittle kwanuko, ndipo kutentha kumakhala kokwera kwambiri.Pamwamba pa makina opangira mphira amatha kukhala ndi carbonization, ndipo zochitika za peeling zimachitika panthawi yosindikiza, zomwe zidzachititsa kuti khalidwe la mphira likhale lochepa, popanda makhalidwe ake abwino, ndipo silingathe kusamutsa inki bwino., Zomwe zimapangitsa kuti ziwonongeke.Masitepe awiri otsirizawa ndi chinsinsi chodziwira ubwino wa rabara.Ngakhale pamwamba pa mphira wodzigudubuza wa mafakitale amawoneka osalala, pali zosokoneza zambiri zazing'ono pamtunda.Kupera ndi kupukuta kumapangitsa kuti chodzigudubuza cha rabara chikhale cholondola kwambiri kukula kwake, kusalala pamwamba, kusuntha kwa inki bwino, komanso kusindikiza kwapamwamba.
