Aluminum Circle for Pop Cans
A sip of ice-cold soda on a hot summer day, an energy drink after exercise—the aluminum can has long been an indispensable packaging partner in our lives. You may never have noticed that this lightweight, airtight, easy-to-open container's core component is actually a small aluminium round plate.
Many people assume that an aluminum can is a single, molded piece, but in reality, its key parts are all processed from aluminum disc circles of different sizes. According to industry standards, the can body, lid, and bottom are all made from aluminum discs through precision stamping and stretching processes.
The can body uses 3004 series aluminum alloy discs. These discs combine excellent formability and corrosion resistance, allowing them to withstand multiple complex processes such as blanking, cupping, and thinning stretching. The final result is a thin can body with a wall thickness of only 0.08~0.10mm, while ensuring sufficient pressure resistance to prevent deformation and breakage during filling and transportation.
Can lids and bottoms are mostly made of 5052 or 3104 series aluminum alloy discs. The former has good corrosion resistance and a smooth surface, and after stamping, it can precisely match the easy-open lid structure. The latter has high tensile strength and excellent deep-drawing performance, ensuring the pressure resistance stability of the can bottom. It can be said that a qualified aluminum disc is the "first line of defense" for the quality of a beverage can.
In the production of aluminum discs for beverage cans, Haomei Aluminum has become a highly representative manufacturer in the industry thanks to its years of technological accumulation and production capacity advantages. As a large-scale aluminum disc supplier, Haomei Aluminum's core advantages are concentrated in three dimensions, precisely meeting the stringent requirements of beverage can production.
Firstly, comprehensive product specifications and precise performance control. Haomei Aluminum's aluminum discs cover multiple series of alloys, including 1, 2, 3, 5, 6, 7, and 8, among which are core models such as 3004, 5052, and 3104 specifically for beverage cans. To address the high material requirements of aluminum can production, the company strictly controls the grain size and elongation of the aluminum coils from the initial production stage. This ensures that the aluminum discs possess excellent deep-drawing and spinning properties, effectively preventing defects such as drawing lines and high lug rates during subsequent processing.
It's important to understand that the lug rate requirement for aluminum can production is typically below 2%. Haomei Aluminum's precise control directly reduces the scrap rate for can manufacturers. Simultaneously, the company's full-process testing of alloy composition, condition, and performance ensures that the performance of each batch of aluminum discs remains stable, making them suitable for high-speed automated aluminum can production lines.
Secondly, excellent surface quality and high material utilization. As food packaging, aluminum cans require extremely high surface cleanliness, allowing no defects such as scratches, oil stains, or oxide spots. Haomei Aluminum's aluminum discs have a smooth, flawless surface, requiring no additional treatment before proceeding to subsequent printing and coating processes, significantly improving can-making efficiency.
More notably, thanks to advanced production equipment and processes, the company achieves a raw material utilization rate of over 80% for its aluminum discs, thus providing a relatively low aluminium circle price for our customers.
Thirdly, flexible customization capabilities and standardized quality assurance. Different brands and types of beverage cans (such as soft drink cans, beer cans, and energy drink cans) have varying requirements for the diameter, thickness, and other specifications of the aluminum discs.
Haomei Aluminum can provide personalized customization according to customer needs, from size adjustments to surface treatments (such as polishing and passivation), comprehensively matching customers' production requirements.
Furthermore, the company's product packaging strictly complies with domestic and international sales standards, ensuring that the aluminum discs are not damaged during transportation and guaranteeing consistent product quality upon delivery to customers.
