Eye shadow palette not welded:

1. When the eye shadow palette has not undergone welding treatment, there are many troublesome problems. First of all, in terms of structural stability, the connections between various parts are not tight enough, and it is easy to loosen and separate. This makes the eye shadow palette prone to internal eye shadow compartments shifting or even the outer shell cracking when slightly bumped during daily carrying and use, seriously affecting the integrity and aesthetics of the product. Secondly, the sealing performance is extremely poor, and external dust, water vapor, etc. can easily enter the interior of the eye shadow palette and contaminate the eye shadow powder. This not only changes the color and texture of the eye shadow, reducing the use effect, but may also breed bacteria, posing a potential threat to eye health. Moreover, during the production and transportation of the unwelded eye shadow palette, due to the lack of a firm connection, parts are likely to fall off, increasing the defective rate and after - sales maintenance costs.

After ultrasonic welding:

2. The eye shadow palette processed by ultrasonic welding technology seems to have undergone a magnificent transformation. In terms of stability, it has achieved a qualitative leap. After welding, all parts of the eye shadow palette are closely combined into a whole, with a solid and durable structure. Whether on bumpy journeys or during frequent daily use, it can remain intact, effectively avoiding problems such as internal structure loosening and damage. In terms of sealing, ultrasonic welding forms a tight barrier, completely isolating external dust, water vapor, etc., ensuring that the eye shadow powder always remains pure and dry. In this way, the color and texture of the eye shadow can remain as new for a long time, the use effect is more outstanding, and it also provides a reliable guarantee for the user's eye health. In addition, from a production perspective, ultrasonic welding
