Requirements for aluminum alloy materials

The pull ring cap material is an aluminum alloy coil or sheet, and different manufacturers choose different material widths and thicknesses according to the cover specifications.


Material requirements:

1. The thickness must be uniform and the tolerance is within ±0.005mm

2. The purity, tensile strength and yield strength of the metal must be uniform


3. In order to prevent the contact between the aluminum alloy and the product, the surface layer of the aluminum material must be coated on both sides, which is also a measure to prevent excessive wear of the mold

4. In order not to cause quality defects and damage the mold during the stamping process, a layer of lubricating oil needs to be applied to the aluminum.
