Aluminium Coil for EOE lid

Introduction of Aluminium Coil for EOE lid
The production process of the easy-open aluminum beverage can is relatively complicated. It is formed by continuous high-speed stamping and riveting of the Aluminium Coil for EOE lid coated with paint film on a special lid-making machine. The made easy-open lid not only requires beautiful appearance, good sealing parts, strong corrosion resistance, but also can withstand some pressure. Therefore, there are higher requirements for the Aluminium Coil for EOE lid.
 
Requirements for Aluminium Coil for EOE lid
Aluminum coils for easy-open lids are required to have high dimensional accuracy and good surface quality, with a thickness tolerance of ±0.005 mm and a width deviation of +1.0-0. In addition, high strength, good formability and uniform performance are required.
 
Thickness of Aluminium Coil for EOE lid
1. The thickness range of the Aluminium Coil for EOE lid is 0.208-0.360mm
2. The width of the Aluminium Coil for EOE lid is 800-1730mm
The pull ring is riveted to the aluminum sheet with notches around the lid, the pull ring is pulled up, the aluminum sheet on the lid is cracked with the notches, and the opening is used as an outlet for beverages.
 
Condition of Aluminium Coil for EOE lid
1. Commonly used alloys and states of cover materials include 3104-h19 aluminum coil, 5052-H19 aluminum coil, etc. The cover material varies with the beverages contained in the can.
2. The commonly used materials of the pull ring are 5182, etc. The thickness and alloy state of the aluminum coil used are determined according to the form of the pull ring and the alloy of the cover material used. Most manufacturers use a slightly thinner aluminum plate than the cover material when producing the pull-type pull ring. In order to ensure that the riveting point is not pulled apart when it is opened, an alloy and state with higher strength than the cover material should be used.
