Aluminium slug is usually produced by aluminium alloy 1050, 1070, 1100,etc. and the alloys mainly belong to pure aluminium series with soft mechanical property suitable for cold impact extrusion.
The shape of aluminum slug include flat round, concave, dome, rectangle with surface tumbled to bear lubricant powder before collapible tube, or aerosol can impact extrusion.
Aluminum slugs are mainly used as raw blank material of aluminium collapsible tubes, aerosol can, food container, costoms containers, electric capacitor shell, etc.
Key quality controls of aluminium slugs used for collapsible tube production
Metal grain size, aluminium slug casted from pure aluminium alloy 1070, Fuchuan Metal keep strict control on the casting process and holding step to gurantee the metal grain in dense and even distribution.
Degassing and impurity removal, Fuchuan Metal has special designed on-line degasing devevice to gurantee the aluminium liquid is purified and degased in high level. The impurity among the casting aluminium may cause pits and extrusion mark on surface of aluminium tubes.
Stamping flaws/Half-moon stamp, we have feeding error correction device on press which inspect and monitor the feeding right on time without misfeeding and stamping scrap.
Aluminum slug hardness control, our mesh belt annealing furnace controls the annealed hardness strictly between 18~19HB, which is the best hardness for aluminium collapsible tube extrusion.
Fuchuan Metal produces more than 400 different gauges of aluminum slug with competitive offer to tens of countries, we welcome you to contact us and establish cooperation for a value-motived and win-win business.
