Automobile Instrument Panel Puncture Welding by Ultrasonic Technology

Automobile Instrument Panel Puncture Welding by Ultrasonic Technology  

Description: 

The auto door panel welding machine is also called the auto door panel interior trim panel welding machine. It uses the ultrasonic puncture welding technology to weld the two door panels together. the two door plank interior strength meet customer requirements, The equipment is designed to be symmetrical piece welding machine, it adopts PLC control parameters, semi-automatic production is realized.

How to use ultrasonic puncture welding technology?

It was decided by product material, best of same material, or a mixture of materials and other materials. It depends on whether the ultrasonic wave of two kinds material can be fused. You can send the material to try to test. 

How to design ultrasonic puncture welding?

Usually it is up and down welding. The characteristics of puncture welding, there will certainly be a scar on one side, the other side may not be seen if thickness. Many customers are concerned about material issues and also they care about how to design. Here we share the actual ultrasonic puncture welding cases. There are some differences in the products of different ultrasonic puncture welding. The content is for reference only.

Specifications:

Gun and Cylinder Type of Horn

Gun type: in accordance with the shape design of human body engineering, ultrasonic start switch is located on the trigger, easy to grasp and use the welding operation, especially suitable for horizontal or vertical.

Cylinder type: for the appearance of design straight, ultrasonic start switch is located outside the cylinder, easy welding and hand carried, can also be installed between the on machine, welding operation for each direction.

Affecting Factors in Dashboard Welding:

With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.3MPa (pressure gauge), sometimes higher. But if the use of high pressure, it will hinder the cylindrical vibration.

The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds. Over time will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds.
