Flat twin screw barrels inoita basa rakakosha mukugadzirwa kwePVC pombi uye profiles. Mashandisirwo ayo mundima mbiri idzi akanyorwa pazasi: Plasticization uye kusanganiswa kwezvinhu: Iyo screw barrel inonyungudika zvizere uye inosanganisa PVC resin uye zvimwe zvinowedzera kuburikidza nekutenderera screw uye nzvimbo yekudziya. Izvi zvinoita kuti PVC zvinhu zvipfave uye zviri nyore kugadzirisa uye kuumba. Extrusion molding: Pasi pechiito chescrew barrel, iyo yakanyungudutswa yePVC zvinhu inoburitswa kuburikidza nefa kuti igadzire tubular kana profil-yakaita chigadzirwa.
Iyo dhizaini uye kugadzirisa kweiyo screw barrel inogonesa kugadzirwa kwepombi uye profiles emhando dzakasiyana uye saizi. Kutonhodza uye kusimba: Mushure me extrusion, pombi kana mbiri inopinda nekukurumidza kutonhora kuburikidza neinotonhora sisitimu yekuomesa zvinhu uye kuchengetedza chimiro chayo. Kucheka uye Kucheka: Shandisa midziyo yakaita semichina yekucheka nemichina yekuchekeresa kugadzirisa saizi uye kupedzisa maitiro emapombi akawedzera uye profiles. Muchidimbu, iyo flat twin-screw barrel inoita basa rakakosha mukugadzirwa kwePVC mapaipi nemaprofiles, kuona iyo plasticization, kusanganisa, extrusion kuumbwa uye kunotevera kugadzirisa kwezvinhu, kuve nechokwadi chemhando uye kushanda kwechigadzirwa chekupedzisira.
