3105 aluminium alloy is used widely for manufacturing screw caps for wine bottles, spirits and non-alcoholic beverages. The alloy contains magnesium, which makes it highly resistant to corrosion. Moreover, it is ductile and has good formability, allowing it to be easily shaped into caps of various sizes and shapes required for different bottle sizes.
The 3105 aluminium sheet for screw caps has excellent deep drawing properties and can be stamped easily with consistent quality. The surface finish of the sheet is smooth and even, enabling printing of logos and other design elements required by the beverage manufacturers.
The sheet is usually supplied in a coil form and undergoes a series of manufacturing steps before it is cut into individual caps. These steps include cleaning, pretreatment, primer and lacquer coatings, printing, and final curing.
Overall, 3105 aluminium sheet is a cost-effective and reliable material for manufacturing screw caps for the beverage industry. It offers excellent durability and protection to the contents of the bottle, while also providing a seal that prevents any leakage or spillage.
