Analysis On The Causes Of Unstable Ultrasonic Welding Products

The first factor that causes the unstable ultrasonic welding is that the frame is not made accurately. The ultrasonic welding machine looks like a device with no difficulty other than the ultrasonic system. In fact, this is a wrong view. Although the ultrasonic generator is the core part of the ultrasonic welding machine, there is also the problem of the plastic welding machine frame in addition to the generator. If the design of a frame is not reasonable and the processing is not precise enough, During the use process, it is very likely to directly affect the welding qualification rate of your product. If the machine is not designed properly, it will also affect the welding fastness of the product if the machine is tilted back. In addition, if the processing is not precise and rough, it is impossible to find the best balance position of the mold when replacing the mold, which may also lead to the failure of welding of the welding product. The solution is to directly replace the good rack, try to do a good job of purchasing before purchasing the machine, and understand the relevant information of the equipment.

The second factor that causes poor ultrasonic welding is that the power of the ultrasonic generator is not enough. Considering that many factories choose cheap machines when buying machines, they ignore the processing and use of other products in the later period of the machine. If the ultrasonic power is not enough, the area of the welding products exceeds the welding range, it will also lead to poor welding. The solution is to purchase plastic welding machine with large power as far as possible to ensure the subsequent use.

The third factor that causes poor ultrasonic welding is the problem of plastic material itself. There are many plastic materials that can be welded by ultrasonic welding. If other materials are added to the materials that can use ultrasonic welding machines, the welding fastness will also be affected. For example, the fastness of the whole welding will be affected after glass fiber is added to the PC. The solution is to use a single thermoplastic material. The above are the common problems that the ultrasonic plastic welding machine is not firmly welded. However, there are also other problems. These are invisible problems that are difficult to find if you don't pay attention.

The fourth factor causing unstable ultrasonic welding: after a period of observation, it was found that some of the reasons were due to the unstable air pressure in the customer's workshop. Only when the machine was used normally at the end of the day, there was no problem of unstable welding. The problem occurred again at normal work hours, so we judged that the unstable air pressure affected the normal welding of the ultrasonic welding machine. Because many equipment that need to use gas during normal work will work at the same time and the pressure of the gas path will decrease. Solution: If large machines are used to weld smaller products, try to replace smaller cylinders, or add an independent air compressor to supply air to the ultrasonic plastic welding machine. If the above troubleshooting fails to solve the problem of unstable ultrasonic welding, most of the problems are related to debugging, or we can find a professional manufacturer for on-site inspection
