1. Lapho uvula isikhunta se-aluminium futhi usika indawo yokusebenza yembobo ye-extrusion ngocingo, yamanje kufanele izinzile, ukuze usayizi wembobo yokufa ngemva kokusika ufane futhi udonga lwembobo lube flat;2. Lapho usika indawo yokusebenza yembobo ye-aluminium extrusion, owamanje akufanele ube mkhulu kakhulu Funda kabanzi
