I-Flat twin screw barrels idlala indima ebalulekileyo ekuveliseni imibhobho yePVC kunye neeprofayili.Ukusetyenziswa kwayo kule miba mibini zidweliswe ngezantsi: Iplastiki kunye nokuxuba izinto eziphathekayo: I-screw barrel inyibilika ngokupheleleyo kwaye ixube i-resin ye-PVC kunye nezinye izongezo nge-screw ejikelezayo kunye nommandla wokufudumala.Oku kwenza izinto PVC ethambileyo kwaye kulula ukusetyenzwa kunye nokumila.Ukubunjwa kwe-Extrusion: Ngaphantsi kwesenzo se-screw barrel, into etyhidiweyo ye-PVC ikhutshwe ngokufa ukuze yenze imveliso ye-tubular okanye iprofayili.
Uyilo kunye nohlengahlengiso lwe-screw barrel luvumela ukuveliswa kwemibhobho kunye neeprofayili zeemilo ezahlukeneyo kunye nobukhulu.Ukupholisa kunye nokuqiniswa: Emva kwe-extrusion, umbhobho okanye iphrofayili ipholisa ngokukhawuleza ngenkqubo yokupholisa ukuqinisa izinto kunye nokugcina imilo yayo.Ukusika kunye nokuNcitshiswa: Sebenzisa izixhobo ezinjengoomatshini bokusika kunye noomatshini bokusika ukulungelelanisa ubungakanani kunye nokugqiba inkqubo yemibhobho ekhutshiwe kunye neeprofayili.Ngamafutshane, i-flat twin-screw barrel idlala indima ephambili kwinkqubo yokuvelisa imibhobho ye-PVC kunye neeprofayili, ukuqonda iplastiki, ukuxuba, ukubunjwa kwe-extrusion kunye nokucutshungulwa okulandelayo kwezinto, ukuqinisekisa umgangatho kunye nokusebenza kwemveliso yokugqibela.
