High quality 8011 bottle cap aluminum sheet

Haomei high quality 8011 bottle cap aluminum sheet is 0.16mm to 0.28mm thick, and H14 or H16 temper. It has good sealing effect, low ear rate and high finish product rate. The edge waviness meet the following standards. First, there are less than 4 waves if the deviation from flat does not exceed 2mm. Second, there are 3 waves if the deviation from flat does not exceed 3mm. Third, as for edge burr, the surface of the sheet must be free from defects such as scratch, corrosion,  dent , brown stain, stain line, residual oil film, pinhole, wrinkle, etc. The thickness tolerance is 0.01mm, width tolerance 0.005mm, length tolerance 0.5mm and the squareness less than 0.3mm if there’s special request.

Aluminum bottle caps are mostly processed on production lines with a high degree of automation, so 8011 bottle cap aluminum sheets must meet strict requirements in material strength, elongation and dimensional deviation. Haomei has clear technical rules for its bottle cap sheets to avoid cracks or creases in the cap making process. The surface of the bottle cap sheet is required to be flat, free of roll marks, scratches and stains. The thickness and width error must not exceed the given figures. The cut sheet pieces should be free from any burs, knife marks and curve edges. During the production process, every aluminium roll is tested in regard of strength, elongation and tensile strength. The finished sheets go through a selective examination for ear rate and bottle making effect. Under such technical and management supports, Haomei is able to supply 8011 bottle cap aluminum sheets for ropp cap manufacturers of various industries.
