Flat twin screw mbiya zimagwira ntchito yofunika kwambiri popanga mapaipi a PVC ndi mbiri.Ntchito zake m'magawo awiriwa zalembedwa pansipa: Pulasitiki ndi kusakaniza zinthu: Mtsuko wa screw umasungunuka ndikusakaniza utomoni wa PVC ndi zowonjezera zina kudzera pa screw yozungulira ndi malo otentha.Izi zimapangitsa kuti zinthu za PVC zikhale zofewa komanso zosavuta kuzikonza ndikuzipanga.Kumanga kwa Extrusion: Pansi pa mbiya ya screw, zinthu zosungunula za PVC zimatulutsidwa kudzera mufa kuti apange tubular kapena mawonekedwe owoneka ngati mbiri.
Mapangidwe ndi kusintha kwa screw mbiya kumathandizira kupanga mapaipi ndi mbiri yamitundu yosiyanasiyana ndi makulidwe.Kuziziritsa ndi kulimbitsa: Pambuyo pa extrusion, chitoliro kapena mbiriyo imazizira mofulumira kudzera mu dongosolo lozizira kuti likhale lolimba ndi kusunga mawonekedwe ake.Kudula ndi Kudula: Gwiritsani ntchito zida monga makina odulira ndi makina odulira kuti musinthe kukula ndikumaliza ntchito yotulutsa mapaipi ndi mbiri.Mwachidule, lathyathyathya amapasa mbiya mbiya imagwira ntchito yofunika kwambiri popanga mapaipi a PVC ndi mbiri, pozindikira pulasitiki, kusakaniza, kuumba kwa extrusion ndi kukonzanso zinthu, kuonetsetsa kuti ntchito yomaliza ndi yomaliza.
