Mapeto

Pomvetsetsa zolakwika zamtundu wa extruder ndi njira zawo zothetsera mavuto, mutha kupitiriza kupanga bwino ndikuchepetsa nthawi yopuma. Kumbukirani, chisamaliro chopewera ndikofunikira. Kuyendera nthawi zonse ma extruder anu, kutsatira ndondomeko yoyenera yothira mafuta, ndi kugwiritsa ntchito zipangizo zamtengo wapatali kungachepetse kwambiri kuchitika kwa zolakwikazi. Ngati mukukumana ndi vuto kupitirira ukatswiri wanu, kukaonana ndi oyenerera extruder katswiri nthawi zonse analimbikitsa.
