Does ultrasonic welding have requirements for products?


With the wide application of ultrasonic welding equipment, more and more plastic parts have been converted from traditional processes to ultrasonic welding. So what are the requirements for ultrasonic welding products? Let’s take a look.


1. The thermal resistance must meet the melting point of the workpiece

After the ultrasonic transducer converts electrical energy into machinery, it is conducted through the material molecules of the workpiece. The acoustic resistance of ultrasonic sound waves in solids is much smaller than that in the air. When the sound waves pass through the joints of the workpiece, the acoustic resistance in the gap is large.  The temperature first meets the melting point of the workpiece, and then a certain pressure is applied to weld the seam. The other parts of the workpiece will not be welded due to low thermal resistance and low temperature.


2. Get out of the misunderstanding of the ultrasonic welding machine

How much output power to use, the oscillation frequency, and the amplitude range should be considered according to factors such as the material of the workpiece, the area of ​​the welding wire, whether there are electronic components in the workpiece, and whether it is airtight or not.


3. Strict inspection

Regular and reliable ultrasonic mold manufacturers have a set of strict inspection procedures for the incoming materials, and the processing dimensions are processed after computer software simulation and verification. Quality is guaranteed. Such a process is usually impossible in a workshop. If the mold is not properly designed, the reaction problem is not obvious when welding small workpieces, and various disadvantages will appear when the power is high. In severe cases, power components will be directly damaged.


The knowledge about ultrasonic welding is introduced here, and I hope it will be helpful to everyone. If you have any supplements or want to inquire about ultrasonic products, please call us.
