Application principle of ultrasonic welding machine

1. Principle
The working principle of the ultrasonic plastic welding machine: using ultrasonic vibration frequency, contact friction generates heat energy to melt and combine plastics. According to the current common ones, it is 20,000 vibrations per second (20kHz) and 15,000 vibrations per second ( 15kHz). In addition, there are several special vibration frequencies. Due to space limitations, only 15kHz and 20kHz are more common for welding.

Direct welding: firstly make materials such as wires or belts overlap each other (for example: riveting, embedding, etc.), and fix the jig on the ultrasonic plastic welding machine, so that the energy converter (HORN) directly generates sound wave vibration performance on it And welding.

Conduction welding: that is, when welding, a distance away from ultrasonic vibration, conduct welding by means of sound wave vibration (for example: plastic shell welding, etc.).

2. Features

A. It can weld thermoplastic plastics other than Teflon.
B. The splicing time is extremely short, usually ranging from 0.5 seconds to 1 second.
C. It can be welded to the joint surface through media such as water and oil.
D. The welding effect can reach a practical level.
E. It can be directly welded with conduction.
F. Material welding energy can vary with plastic materials, and not all materials for ultrasonic vibration. Only suitable surface vibrations are used to generate heat, so there is no concern about scratches on the surface of the product. This is a feature of conductive welding. When the harder plastic is welded, it can exert its welding effect better.
G. Ultrasonic welding will not produce the toxicity like chemical agents, it is a safe welding
Then processing.

3. Application

Ultrasound has a very wide range of applications. Generally, we are familiar with being used in medicine. In the industrial field, you may find that ultrasound is also in the application range of your own products. It can improve your efficiency and quality. , Will also be our common desire.

Its scope of application:

1. Welding;
2. Embedding;
3. Forming;
4. Riveting;
5. Spot welding;
6. Vibration (removal);
7. Hot melt.
