Aluminum cover production, driven by punch stamping die stamping.
The vial aluminum cap is made of 8011 aluminum alloy strip , and aluminum alloy strip with different specifications needs to be produced with aluminium alloy plate of different specifications. According to whether the 8011 aluminum alloy strip coating, aluminum cover for ordinary aluminum cap (ie non coating), single coated aluminum cover and double coated aluminum cover three kinds.
As the mold is divided into stretch die and cut ring mold, the production of the cover also has tension and cut ring. Tensile aluminum cover process is relatively simple, the material utilization rate and efficiency than the ring cutting aluminum high, but the difference between the convex and concave aluminum cap (i.e. the maximum height and the minimum height of aluminum cap slightly larger difference).
