Aluminium Slug

Aluminium slug is a kind of aluminium sheet in shape of flat round, rectangle, oval, dome, concave,etc. The aluminium slugs usually choose aluminium alloy 1050, 1070 for package containers. And 3003, 6061, 6063 alloys are mostly used for auto part, electric part production. The aluminium ingots are melt and cast into thick coil, then the coil is rolled to designed thickness in cold rolling mill. The press mill will stamp the aluminium slug with required diameter or shape out of the mother coil. The aluminium slugs after stamping bear internal stress and slim oil film so we have to heat it in annealing furnace to get the metal softer and oil film evaporated. The aluminium container extrusion bears high force upon the aluminium slugs in order to get the metal flow and designed container shape. So we process the aluminium slug in vibration machine and get the surface roughness to carry on lubricant powder before extrusion. Then the slugs are packed in carton and ready for delivery.
