Ucingo lwe-PVC lwenziwe ngomshini wokukhipha izikulufo ezimbili.
Ukukhishwa kwe-PVC kuyinqubo yokukhiqiza esheshayo lapho ipulasitiki eluhlaza incibilikiswa khona bese yenziwa iphrofayili ende eqhubekayo. Ukukhishwa kukhiqiza imikhiqizo efana namaphrofayili epulasitiki, amapayipi epulasitiki, izinsimbi zokubiyela ze-PVC, ozimele bamafasitela e-PVC, amafilimu epulasitiki, amashidi, izintambo, kanye namaphrofayili ocingo lwe-PVC, asetshenziswa kabanzi emikhakheni eminingi.
Le nqubo yokukhipha iqala ngokufaka i-PVC compound kusuka ku-hopper iye emgqonyeni we-extruder. I-compound incibilikiswa kancane kancane ngamandla omshini akhiqizwa yizikulufo ezijikayo kanye nama-heater ahlelwe eceleni komgqomo. I-polymer encibilikisiwe ibe isiphoqelelwa kudayi, noma ebizwa ngokuthi ama-extrusion molds, abumba i-PVC compound ibe yisimo esithile, njengesigxobo socingo, i-fence rail, noma ama-fence pickets aqina ngesikhathi sokupholisa.
Ekukhishweni kwe-PVC, izinto ezihlanganisiwe ezingavuthiwe zivame ukuba sesimweni sempuphu edonswa amandla adonsela phansi esuka kwi-hopper efakwe phezulu iye emgqonyeni we-extruder. Izithasiselo ezifana ne-pigment, ama-UV inhibitors kanye ne-PVC stabilizer zivame ukusetshenziswa futhi zingaxutshwa ne-resin ngaphambi kokufika kwi-hopper. Ngakho-ke, maqondana nokukhiqizwa kocingo lwe-PVC, siphakamisa amakhasimende ethu ukuthi ahlale nombala owodwa kuphela ngokulandelana okukodwa, noma izindleko zokushintsha isikhunta se-extrusion zizoba phezulu. Kodwa-ke, uma amakhasimende kufanele abe namaphrofayili anemibala ngokulandelana okukodwa, imininingwane ingaxoxwa.
Le nqubo ifana kakhulu nokubumba umjovo wepulasitiki kusukela endaweni yobuchwepheshe be-extruder, nakuba ihlukile ngoba ngokuvamile iyinqubo eqhubekayo. Nakuba i-pultrusion inganikeza amaphrofayili amaningi afanayo ngobude obuqhubekayo, ngokuvamile ngokuqinisa okwengeziwe, lokhu kufezwa ngokukhipha umkhiqizo oqediwe esikhumbeni esikhundleni sokukhipha i-polymer encibilikayo ngesikhunta. Ngamanye amazwi, ubude bephrofayili yocingo, njengezigxobo, imisele, nama-picket, konke kungenziwa ngokwezifiso ngobude obuthile. Isibonelo, ucingo oluphelele lobumfihlo lungaba ukuphakama okungu-6ft ngobubanzi obungu-8 ft, futhi lungaba ukuphakama okungu-6ft ngobubanzi obungu-6 ft. Abanye bamakhasimende ethu, bathenga izinto zocingo ezingavuthiwe, bese besika ngobude obuthile endaweni yabo yokusebenzela, bese benza uthango oluhlukile lokuchaza ukuze bahlangabezane nazo zonke izidingo zamakhasimende abo.
Ngakho-ke, sisebenzisa ubuchwepheshe be-mono extrusion ukukhiqiza izinsika, ama-rails nama-picket ocingo lwe-PVC, futhi sisebenzisa ubuchwepheshe bokujova kanye nemishini ukukhiqiza ama-post caps, izixhumi, kanye nama-picket points. Kungakhathaliseki ukuthi izinto zenziwe yimishini yokukhipha noma yokujova, onjiniyela bethu bazolawula imibala ukuthi ihlale ibekezelelana kusukela ekuqaleni kuze kube sekupheleni. Sisebenza embonini yocingo, siyazi ukuthi amakhasimende akhathalelani, sibasize bakhule, yilowo umgomo kanye nenani le-FenceMaster.
