For the medical industry, how to determine the quality of an aluminum-plastic combination cover is an important issue. Many industries have different quality requirements for aluminum-plastic combination covers. These differences can be reflected by the outer tube of the aluminum-plastic cover, which reflects the different quality of the cover. The size of the riveting point between the aluminum-plastic cover and the plastic cover needs to be consistent, the surface should be smooth, the thickness should be uniform, and there should be no burrs. The color of the aluminum cover should also be consistent with the color change of the plastic cover. The diameter of the riveting point between the aluminum cover and the plastic cover should be larger than the diameter of the riveting hole on the aluminum cover. The automatic forming function of the medicinal aluminum-plastic combination cover can all meet the above requirements. However, the appearance of manually riveted aluminum-plastic covers will show significant differences from that of mechanically riveted aluminum-plastic covers. The surface of manually riveted aluminum-plastic covers will have unevenness, non circular edges, brushed edges, and other phenomena. A more obvious point is that when manually riveted aluminum-plastic covers are riveted with manual tools, it is likely that due to poor control of the electric heating temperature, the material will be heated unevenly, leading to heating, and more seriously, there may be burnt phenomenon. In addition, the quality of the aluminum-plastic cover can also be determined by checking the gap between the aluminum cover and the plastic cover. The aluminum-plastic cover processed by mechanical equipment has no gap between the aluminum cover and the plastic cover, and is tightly bonded; However, manually riveted aluminum-plastic covers cannot apply as much pressure as mechanical processing, resulting in a large gap between the aluminum and plastic covers.
