Why is ultrasonic processing more adopted for plastic water cup processing?

Stainless steel water cups can be processed by various welding methods, including laser welding, argon arc welding, etc. What methods should be used for plastic water cups?

Due to the particularity of plastic, welding cannot be used like stainless steel. It is caused by the inability of plastics to withstand high temperatures, and of course glue cannot be used for bonding.

First of all, glue is not environmentally friendly or safe and harmful to the human body. Secondly, the glue is seriously affected by the environment. Even some special glues that can meet the food requirements will open due to the influence of humidity and temperature for a long time. Therefore, the processing of plastic water cups, especially the combination of the various accessories of the cup lid, adopts ultrasonic methods. Through high-frequency vibration, the plastic in contact will form high-frequency friction, which will melt locally after heating, and then the two will be firmly together.

There are many ultrasound methods, among which ordinary ultrasound and rotary ultrasound are the most used by our company. Ultrasonic processing is not only strong, but also beautiful.
