Aluminum Bottle Caps
- Nov 09, 2018 -

Aluminum bottle caps are usually processed on production lines with high degree of automation, so the strength, elongation and size deviation of materials are strictly required, otherwise they will break or crease during processing. In order to ensure that the cap is easy to print after forming, flat surface, no roll marks, scratches and stains are required for the cap material. Generally, the alloy states are 8011-H14, 3003-H16, etc. The material specifications are generally 0.20 mm to 0.23 mm in thickness and 449 mm to 796 mm in width. The production of aluminium bottle cap materials can be made by hot rolling or continuous casting and rolling, respectively, and by cold rolling. At present, China's anti-theft cover material production plant mostly uses continuous casting and continuous rolling billet, which is superior to cast rolling billet.
