Some notices in ultrasonic plastic welding

发布者:灵科超声波 发布时间:2018/7/20
The ultrasonic plastic welding plays an important role in the miniaturization of electronic products. The precision plastic welding ensures the beautiful appearance and consistency of the electronic products, and has been widely recognized in the industrial production. In the use of ultrasonic welding, no attention should be paid to the use of welding. There will be some problems. Different welding materials, welding area, electronic components and air tightness are embedded in the plastic parts. It is necessary for the professional technicians to guide the adjustment in order to achieve the best effect of ultrasonic plastic welding.

1. the area of the ultrasonic welding seam is within the scope of the machine.

The larger the area of the ultrasonic welded joint, the greater the dispersion of the high-frequency vibration energy. The welding effect will be worse and the welding requirements can not be achieved. According to the principle of ultrasonic longitudinal propagation, the larger the loss energy is, the ultrasonic welding seam is controlled within 6 centimeters, the welding line is suitable for 30-80 wire, the thickness of the plastic product is greater than 2 millimeters, so the best effect can be achieved. Otherwise, the replacement of the ultrasonic welding machine of other frequencies will be considered.

2. ultrasonic welding to meet the specific melting point of plastic

Ultrasonic welding of plastic products need to understand the melting point of different plastics. Through the reasonable welding seam design and welding time setting, the product weld seam reaches the specific melting point temperature, exerts certain pressure, and the joint position of the product is fused. If the temperature of the plastic product is not reached, the welding will fail.

3.Importance of welding joint in ultrasonic welding machine

Ultrasonic welding head needs to be simulated and calibrate by computer software, which meets the welding needs of products and is processed by high-precision CNC machine tools. Rigorous design and inspection procedures are the guarantee of the quality of welded joints and the guarantee of the quality of plastic products.

4.Output power stability of ultrasonic welding machine

For different plastic products, ultrasonic welding machines with different output power are needed. In order to reduce the time of adjusting the machine and reduce the problem caused by human error, it can be used to reduce most of the problems by using the ultrasonic automatic frequency tracking welding machine of the Department of science and technology. The function of automatic frequency modulation makes the use of ultrasonic welding machine more convenient.
