Flat twin screw barrels e phetha karolo ea bohlokoa tlhahisong ea liphaephe tsa PVC le profiles. Ts'ebeliso ea eona masimong ana a mabeli e thathamisitsoe ka tlase: Plasticization le ho kopanya thepa: The barrel ea screw e qhibiliha ka botlalo ebe e kopanya resin ea PVC le li-additives tse ling ka screw e potolohang le sebaka sa ho futhumatsa. Sena se etsa hore thepa ea PVC e be bonolo 'me e be bonolo ho e sebetsa le ho e bōpa. Extrusion molding: Tlas'a ts'ebetso ea "screw barrel", "PVC" e entsoeng ka ho qhibilihisoa e ntšetsoa ka har'a thipa ho etsa sehlahisoa sa tubular kapa profil.
Moralo le ho lokisoa ha moqomo oa screw o etsa hore ho be le liphaephe le liprofaele tsa libopeho le boholo bo fapaneng. Ho pholisa le ho tiisa: Ka mor'a extrusion, phala kapa profil e kena ho pholile ka potlako ka mokhoa oa ho pholisa ho tiisa thepa le ho boloka sebōpeho sa eona. Ho Seha le ho Poma: Sebelisa lisebelisoa tse joalo ka mechini e sehang le mechini e pomang ho lokisa boholo le ho phethela tšebetso ea liphaephe le li-profile tse fetisitsoeng. Ka bokhutšoanyane, sekoti se sephara se nang le marang-rang se phetha karolo ea bohlokoa ts'ebetsong ea tlhahiso ea liphaephe tsa PVC le profiles, ho hlokomela polasetiki, ho kopanya, ho bopa extrusion le ts'ebetso e latelang ea thepa, ho netefatsa boleng le ts'ebetso ea sehlahisoa sa ho qetela.
