Problems solved by technology

[0002] Aluminum packaging bottle caps are currently popular new packaging materials in domestic and foreign markets. Compared with traditional plastic or tinplate bottle caps, aluminum bottle caps have better sealing performance, high pressure resistance, corrosion resistance, beautiful appearance and environmental protection. At present, the domestic aluminum cosmetic bottle caps are mainly made of 1070, 1050, 5005 and other aluminum and aluminum alloys, which generally have the disadvantages of darkening the light effect after anodizing the base cap, high ear making rate, and easy to break. The quality of cosmetic bottle caps is at the low-end level, which cannot meet the high-quality requirements

Embodiment 1

[0031] Taking the finished product specification as an example of the production of an aluminum strip with a thickness of 0.4 mm*width of 1200 mm, a method for manufacturing an aluminum strip for a cosmetic bottle cap of the present invention is illustrated, comprising the following steps:

[0032] (1) Prepare an ingot, the ingot includes the following elements by weight percentage: Si≤0.08%, Fe≤0.1%, Cu≤0.03%, Mn≤0.02%, Mg≤0.02%, 0.01%≤Ti≤0.02%, The balance is Al, the grain size of the ingot is ≤ grade 1, and there are no metallurgical quality defects such as inclusions, severe segregation nodules, and porosity. It meets the requirements of "Deformed Aluminum and Aluminum Alloy Flat Ingot YS / T 590-2006". Head and tail specifications: thickness 520mm*width 1320mm*length 4500mm;

[0033] (2) Face milling: the amount of face milling for the large face of the ingot is 20~25mm / face, and the amount of face milling for the side is 15~20mm / face;

[0034] (3) Homogenized heating: ...

Abstract

The invention discloses a production method of an aluminum strip for a cosmetic bottle cap. The production method comprises the steps of: (1) preparation of an ingot and adoption of a new alloy, wherein the ingot comprises the following elements in percentage by weight: not more than 0.08% of Si, not more than 0.1% of Fe, not more than 0.03% of Cu, not more than 0.02% of Mn, not more than 0.02% of Mg, not more than 0.02% and not less than 0.01% of Ti, and the balance of Al; (2) surface milling; (3) uniform heating; (4) hot rolling; (5) cold rough rolling; (6) cleaning; (7) intermediate annealing; (8) cold finish rolling; (9) stretching, bending, straightening and cleaning of trimmings; and (10) checking. The aluminum strip has such excellent characteristics as smooth and bright surface, stable mechanical performance, precise dimensional tolerance, easy punch forming, low earing ratio after punching of the bottle cap and good anodizing effect, and is suitable for producing top-grade cosmetic bottle cap.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy materials, in particular to a method for manufacturing a high-grade cosmetic bottle cap aluminum strip with a thickness of 0.2-1.2 mm. Background technique [0002] Aluminum packaging bottle caps are currently popular new packaging materials in domestic and foreign markets. Compared with traditional plastic or tinplate bottle caps, aluminum bottle caps have better sealing performance, high pressure resistance, corrosion resistance, beautiful appearance and environmental protection. At present, the domestic aluminum cosmetic bottle caps are mainly made of 1070, 1050, 5005 and other aluminum and aluminum alloys, which generally have the disadvantages of darkening the light effect after anodizing the base cap, high ear making rate, and easy to break. The quality of cosmetic bottle caps is at the low-end level, which cannot meet the high-quality requirements. Contents of the invention...
