- PRODUCT DETAIL
Aluminum bottle caps are mostly processed on production lines with a high degree of automation. Therefore, the material strength, elongation and dimensional deviation requirements are very strict, otherwise cracks or creases will occur during processing.
Material requirements: The surface of the bottle cap material is flat, without rolling marks, scratches and stains.
Common alloy state: 8011-H14, 3003-H16, etc.
Material specifications: the general thickness is 0.20mm-0.23mm, and the width is 449mm-796mm.
Production method: The production of aluminum bottle cap materials can be made by hot rolling or continuous casting and rolling, and cold rolling. At present, the production plants of my country's defense thief cover material mostly use continuous casting and rolling billets, which is better than casting and rolling billets.
With technological innovation, the functions and production methods of aluminum bottle caps are also developing in the direction of diversification and high-end production. Aluminum bottle caps are not only mechanized and large-scale, but also low-cost, pollution-free, and can be recycled. Therefore, in the future wine bottle caps, we may foresee that aluminum bottle caps will still be the mainstream.
