I believe everyone is very familiar with the Aluminum cap. You will see it on every cosmetic bottle, but everyone only knows its usefulness. Do you know what kinds of classifications it has? There are mainly screw caps, snap caps, welded caps, etc. And the production process and role of different Aluminum caps are also different. In this article, the editor will give you a detailed introduction to the basic classification of Aluminum caps and the factors that affect the processing quality of Aluminum caps. If you are interested, let's take a look! Here are some answers.

What are the basic classifications of Aluminum caps?


As the name suggests, a screw cap refers to the Aluminum cap through its screw structure, and the container is connected and matched by rotation. Thanks to the advantages of the thread structure, when the screw cap is tightened, a relatively large axial force can be generated through the occlusion between the threads, and the self-locking function can be easily realized.

Welded cover

A type of Aluminum cap in which the bottle mouth is directly welded to the flexible package using welding ribs and other structures is called a welded cap. It is a derivative of the screw cap and the snap cap, but the liquid outlet of the container is separated separately and assembled on the cap.

Factors affecting the processing quality of Aluminum cap.

First, if the filling pressure is too high and the speed is too fast, it will cause mold expansion and cause flashing. The filling pressure and speed should be appropriately reduced, or the melt temperature should be lowered to increase the viscosity. Second, if the holding pressure is too large, the Aluminum material will be forced to condense, and there will be large residual stress, which will reduce the strength and may cause overflow. The holding pressure should be appropriately reduced. Third, if the temperature of the material pipe or the hot runner temperature is too high, the viscosity of the melt is reduced, and the fluidity is too good. The temperature can be appropriately lowered, or the injection pressure can be appropriately reduced. Fourth, if the mold temperature is too high, not only will the front bend, but also defects such as Aluminum cap deformation. You can reduce the temperature of the mold by lowering the temperature of the chiller or increasing the waterway. Fifth, the injection switching position is improper, and the switching position is increased or the dose is decreased.

I believe that after reading the article, everyone has a detailed understanding of the basic classification of Aluminum caps and some knowledge that affects processing.
