Ukuqonda imigaqo yenkqubo yokubumba umphunga we-extrusion, iingenelo, kunye nezinto ezinefuthe

Ukubumba i-Extrusion blow (EBM) yinkqubo esetyenziselwa ukuvelisa iibhotile zeplastiki ezingenanto, izikhongozeli, kunye nezinye iimilo kusetyenziswa i-polyethylene enoxinano oluphezulu (HDPE) okanye i-polypropylene (PP). Ibandakanya ukufudumeza ii-pellets zeplastiki okanye ii-flakes zibe kwimeko enyibilikisiweyo, emva koko zikhutshwe ngedayi ukuze zenze i-parison ebunjwe kwangaphambili. Le parison emva koko ifuthwa ngumoya okanye i-nitrogen, ipholiswe, kwaye ikhutshwe kwi-mold.

Iingenelo ze-EBM ziquka ukukwazi kwayo ukuvelisa iimilo ezintsonkothileyo, amazinga aphezulu emveliso, kunye namandla amahle oomatshini. Ikwabiza kancinci xa ithelekiswa nezinye iinkqubo zokubumba. Nangona kunjalo, i-EBM ayifanelekanga kuzo zonke izixhobo kwaye inokufuna izixhobo ezikhethekileyo kunye nezixhobo.

Ezinye izinto ezichaphazela i-EBM ziquka ukukhethwa kwezinto, uyilo lomatshini, iimeko zenkqubo, kunye noyilo lwesikhunta. Ukukhethwa kwezinto kubalulekile, njengoko ezinye izinto zinamaqondo okunyibilika ahlukeneyo, ubungqabavu, kunye neempawu zobushushu. Uyilo lomatshini kufuneka luqinisekise ukuxubana okufanelekileyo kwezinto, ukufudumeza, kunye nokupholisa ukuze kufezekiswe imveliso oyifunayo. Iimeko zenkqubo ezifana noxinzelelo lwe-injection, isantya sesikrufu, kunye nexesha lokupholisa zinokuchaphazela umgangatho wemveliso yokugqibela. Uyilo lwesikhunta lubalulekile ekuqinisekiseni umgangatho wemveliso olungileyo, ukucoceka lula, kunye nokuthembeka kwexesha elide. Ngamafutshane, i-EBM yinkqubo yokubumba eguquguqukayo nengabizi kakhulu enokuvelisa iimilo ezintsonkothileyo kunye namazinga aphezulu emveliso. Nangona kunjalo, ifuna ukukhethwa kwezinto ngononophelo, uyilo lomatshini, kunye neemeko zenkqubo ukuqinisekisa imveliso yokugqibela esemgangathweni ophezulu.
