3105 and 8011 aluminum closure sheet have high strength, excellent oxidation resistance and good ductility, which makes them perform well in the bottle cap manufacturing process. These aluminum alloy materials can withstand complex stamping and deep drawing processes to ensure the sealing and durability of the bottle caps, especially suitable for carbonated beverages, juices, dairy products and pharmaceutical packaging.

3105 aluminum sheet is an aluminum-manganese alloy with good rust resistance, electrical conductivity and plasticity. It has high plasticity, good corrosion resistance and good weldability in the annealed state. These characteristics make it one of the preferred materials for manufacturing beverage bottle caps. 8011 aluminum foil has good formability, high earing rate and flatness, which can ensure the quality of the bottle caps during deep drawing. It is often used for swing-off anti-theft (ROPP) bottle caps for wine bottles and other beverage bottles.

Advantages of aluminum alloy bottle cap materials:

1. Good sealing performance: aluminum plate has good flexibility and elasticity, which can effectively prevent beverage leakage and deterioration, and extend the shelf life.

2. Easy to process and form: It has excellent forming performance and can be made into bottle caps of different shapes and sizes through various processing methods such as stamping, stretching, and spinning.

3. Light weight: low density, light bottle caps, convenient use and reduced transportation costs.

4. Recyclability: It has good recyclability, conforms to the concept of environmental protection, and is convenient for resource recycling.

5. Aesthetics: Smooth surface, metallic luster, enhance product image, suitable for a variety of decorative treatments.

6. Rust and corrosion resistance: good protective performance, protect beverages from external damage.

3105 & 8011 aluminum alloy bottle cap material production process:

1. Raw material selection: Select high-purity and stable quality aluminum alloy ingots to ensure that the chemical composition of 3105 and 8011 aluminum alloys meets the standards, and ensure the quality of aluminum sealing plates from the source.

2. Melting and casting: Precisely control the temperature, time and atmosphere during melting to avoid component segregation, and adopt advanced casting technology to ensure uniform performance of aluminum alloy ingots.

3. Rolling processing: Precisely roll the aluminum sealing plate through multiple rolling processes, control the rolling speed, pressing amount and tension, ensure thickness accuracy, flatness and surface quality, and perform intermediate annealing to improve material properties.

4. Surface treatment: Improve the corrosion resistance, wear resistance and decorativeness of the aluminum sealing plate. Anodizing, painting, coating and other processes are commonly used. Strictly control the composition and parameters of the treatment liquid to ensure uniform treatment quality.
