The mechanical properties of anti-theft bottle cap aluminum foil, the ear-making rate and the effect of punching bottle caps of 8011 aluminum alloy casting and rolling blanks under different homogenization annealing processes and processing rates have determined the optimal process for producing anti-theft bottle cap aluminum foil from casting and rolling blanks. Product quality meets user requirements. Aluminum alloys for cast-rolled bottle cap materials are widely used in bottle caps for various wine bottles, beverage bottles, medicinal bottles, etc., and can meet the high-quality requirements of domestic and foreign bottle cap processing enterprises for this variety.
Aluminum bottle caps are mostly processed in a production line with a high degree of automation, so the requirements for the strength, elongation and dimensional deviation of the material are very strict, otherwise cracks or creases will occur during processing. In order to ensure the convenience of printing after the bottle cap is formed, the surface of the bottle cap material is required to be flat, without rolling marks, scratches and stains. The alloys generally used are 8011-H14, 3003-H16, etc., and the thickness of the material specifications is generally 0.20- 0.23mm, width 449-796mm.
8011 aluminum alloy, as the main anti-theft cover material, not only has good deep drawing performance and low ear-making rate, but also has a certain strength after being baked in the cover-making process. The production of 8011 aluminum foil bottle cap materials can be mechanized, and has the advantages of large-scale, pollution-free, recyclable, etc., and is widely used in daily life.
3003 aluminum foil is an aluminum alloy with manganese as the main alloying element, which cannot be strengthened by heat treatment. A kind of anti-rust aluminum widely used, the addition of a small amount of Mg significantly refines the crystal of the alloy after annealing, and improves the tensile strength and elongation. It has high plasticity and good welding performance. , corrosion resistance, easy processing and molding, can well meet the needs of users.
