In recent years, aluminum bottle caps are more and more widely used in our daily life, especially for the packaging of wines, beverages and medicines and health products.
Aluminum bottle caps are simple in appearance, finely made, and advanced printing technology can meet the effects of consistent color and exquisite patterns, bringing consumers an elegant visual experience; in addition, aluminum bottle caps also have good airtightness and can meet high temperatures.Special requirements such as cooking and sterilization.Therefore, the performance is superior and it is widely used.
Take out an aluminum bottle cap, and the aluminum friends who pay attention to it should find that there are various lines on the surface. These unobtrusive designs are made through multiple production processes. Aluminum bottle caps are mostly processed in production lines with a high degree of automation, so 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 roll marks, scratches and stains.
Common alloy state: 8011-H14, 3003-H16, etc.
Material specifications: general thickness is 0.20mm-0.23mm, width is 700mm-1100mm.
Production method: The production of aluminum bottle cap materials can be made by hot rolling or continuous casting and rolling. At present, the production plants of my country's defense thief cover material mostly use hot rolling, which is better than casting and rolling billet.
With technological innovation, the functions and production forms of aluminum bottle caps are also developing in the direction of diversification and high-grade. 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.
