In addition to good deep drawing performance and low ear-making rate, aluminum alloy bottle cap materials also have certain strength advantages after being baked in the cap making process. Aluminum bottle cap materials are very advantageous in terms of sealing and aesthetics, so the aluminum market for bottle caps will become better and better.
The stretching length of the aluminum bottle cap is relatively large, so it is necessary to choose a material with a good elongation. Usually, the base material of bottle cap material aluminum plate is made of 8011 aluminum foil, 3003 aluminum foil and 3004 aluminum plate. 1050 aluminum plate and 1060 aluminum plate are also used. Choose which alloy aluminum plate to use according to the stretching length of different products.
Aluminum bottle caps are mostly processed on a production line with a high degree of automation, so there are strict requirements on the strength, elongation and dimensional deviation of the material, otherwise cracks or creases will occur during deep drawing. In order to ensure the convenience of printing after the bottle cap is formed, the aluminum surface of the bottle cap material is required to be flat, without rolling marks, scratches and stains. The aluminum plate of the bottle cap material has 8001-HI4, 3003-H16, etc. The material specifications generally have a thickness of 0.20~43.3mm, an allowable tolerance of ±0.1%, and a width of 449-796mm.
