Regarding the sealing method of aluminum caps, I would like to briefly introduce you: The recycling and selection of aluminum caps, the selection of aluminum caps, according to the size, structure and shape of the aluminum caps, have a great impact on the sealing quality of large infusions. The size should be determined according to the diameter of the mouth of the salt water bottle. Although there are related regulations on the diameter of the bottle mouth, some manufacturers do not strictly implement the standard, which causes the size to disagree. In addition, the specifications purchased by various manufacturers in the medical unit are quite messy.
Therefore, in the case of the specification of aluminum caps, saline bottles of different calibers should be selected, and suitable bottle caps should be selected. The shape of the aluminum cap is generally multi-position flat top, and the shape after pressing depends on the capping mold of the capping machine. If the mother and child and the flat top are sealed into an aluminum cap flat top shape, they will often not be tightly attached to the bottle stopper, which will easily cause looseness. However, if the mold is changed to rounded corners, this shortcoming can be overcome after being suppressed.
