Kugwiritsiridwa ntchito kwa screw barrel m'munda wa SPC pansi kuli ndi mbali zingapo: Kusanganikirana kwazinthu: Mtsuko wa screw ndi chimodzi mwazinthu zofunikira popanga zida zofunika pakuyala pansi kwa SPC.Zimasakaniza zinthu za PVC ndi zowonjezera zina (monga plasticizers, stabilizers, etc.) kuti apange zinthu zophatikizika zomwe zimafunikira pansi pa SPC.Plasticization: mbiya yowononga imagwiritsa ntchito kutentha kwambiri komanso mphamvu yamakina kuti ipangitse zinthu za PVC.
Kupyolera muzitsulo zozungulira, zinthu za PVC zimatenthedwa ndikugwedezeka mkati mwa mbiya kuti zifewetse ndi pulasitiki kuti zipangidwe.Kankhirani kunja: Pambuyo popanga pulasitiki, mbiya yomangira imakankhira zinthu zapulasitiki kuchokera mumbiyayo posintha liwiro lozungulira komanso kuthamanga.Kupyolera mu zipangizo monga nkhungu ndi kukanikiza odzigudubuza, zinthu amawumbidwa mu mawonekedwe a mapanelo pansi SPC.Mwachidule, kugwiritsa ntchito screw mbiya m'munda wa SPC pansi makamaka imayang'ana pa kusakaniza zinthu, plasticizing ndi kukankhira kunja.Ndi chida chofunikira kwambiri popanga ma SPC pansi, kuwonetsetsa kuti zinthu zapansi zili ndi magwiridwe antchito komanso mtundu.
