Aluminum and aluminum alloy bottle cap materials are a new type of bottle cap sealing material. They are not only beautiful and easy to open, but also have the function of preventing counterfeit goods. Therefore, it has been widely used in the sealing packaging of beverage bottles, wine bottles, cosmetic bottles, medicine bottles, etc. at home and abroad.
Since aluminum covers are mostly processed on production lines with a high degree of automation, the performance requirements for the materials are relatively high. The raw material of medical caps is 8011-H16 aluminum coil sheet, which is processed into bottle caps through special technology. Medical aluminum caps are thin and easy to open. They are widely used in pharmaceutical oral liquids. Aluminum caps also play their advantages in sealing bottled liquids.
The roll end surface should be neat and free of cracks, burrs, warped edges, ruffles, burrs, bumps, etc.
The entire roll is staggered <2mm, tower type <5mm
The strip is freely unfolded on the platform, and the wave height is <3mm; the number of waves within any one meter does not exceed 3
The surface should be smooth, clean and free of oil spots, and wrinkles and serious indentations are not allowed.
The 1 series, 3 series, 5 series and 8 series products produced by Mingtai can all be used in the production of bottle cap materials. Common ones include 1060 aluminum coil sheet, 3104 aluminum coil sheet, 3105 aluminum coil sheet, 5052 aluminum coil sheet, and 1235 aluminum foil. , 8011 aluminum foil, etc. Mingtai Aluminum is a domestic aluminum plate and strip processing enterprise that independently developed a “1+4” hot rolling production line. It accurately integrates the profile plate crown control system, which greatly improves product quality.
A: Width and thickness tolerances are implemented according to the requirements of the process card.
B: The surface is smooth, without defects such as cracks, bubbles, penetration pores, metal and non-metal intrusion, light and dark streaks, etc.
C: During the rolling process, the surface quality shall be randomly checked at least every 3 rolls, and the surface quality of each roll of the finished product shall be checked.
D: Strictly monitor the quality of slices to ensure there are no burrs, knife back marks, or ruffles.
In addition to good deep drawing performance and low lug-making rate, aluminum alloy bottle cap materials also have certain strength advantages after being baked in the cap-making process. Aluminum bottle cap materials have great advantages in terms of sealing and aesthetics, so the market for aluminum bottle caps will get better and better.
