Ts'ebeliso ea "screw barrel" tšimong ea SPC flooring e na le lintlha tse 'maloa: Ho kopanya lintho tse bonahalang: The screw barrel ke e' ngoe ea lisebelisoa tsa bohlokoa bakeng sa ho etsa thepa e hlokahalang bakeng sa fatše SPC. E kopanya thepa ea PVC le li-additives tse ling (tse kang li-plasticizers, stabilizers, joalo-joalo) ho etsa lisebelisoa tse nang le motsoako o hlokahalang bakeng sa fatše SPC. Plasticization: Moqomo oa screw o sebelisa mocheso o phahameng le matla a mochini ho etsa polasetiki ea thepa ea PVC.
Ka screw e potolohang, thepa ea PVC e futhumatsoa 'me e tsosoa ka hare ho moqomo ho etsa hore e be bonolo le polasetiki bakeng sa ho boptjoa ka mor'a moo. Sututsa kantle: Kamora ts'ebetso ea polasetiki, moqomo oa screw o sutumelletsa thepa ea polasetiki ka ntle ho moqomo ka ho fetola lebelo la ho potoloha le khatello. Ka lisebelisoa tse kang hlobo le li-rollers tse hatellang, thepa e bōptjoa ka sebōpeho sa liphanele tsa fatše tsa SPC. Ka bokhutšoanyane, ts'ebeliso ea "screw barrel" tšimong ea SPC flooring e shebana haholo le ho kopanya thepa, polasetiki le ho sutumelletsa kantle. Ke sesebelisoa sa bohlokoa tlhahisong ea mekato ea SPC, ho netefatsa hore thepa ea fatše e na le ts'ebetso le boleng bo hlokahalang.
