In this age of high-tech industrial manufacturing, not many people have heard of or know about ultrasonic welding. This article will seek to clarify a bit about what it is and its advantages and disadvantages.
Ultrasonic welding is the process of joining plastic together by using mechanical vibration energy created from ultrasonic frequencies. This process bonds the two pieces of plastic together on their work surfaces. It is regarded as the cleanest and most reliable way to weld plastics together. Many companies such as herrmann ultrasonics have made this type of welding their forte.
The benefits of ultrasonic welding are that its uses are quite diverse. Beyond just plastic, it can join metals such as tin, copper, aluminum, and many others. It is not very efficient for welding semiconductor materials, however. The power that the process uses is quite small, especially when it is compared to other welding methods. This is one of the reasons why it is so popular with companies such as herrmann ultrasonics.
Another benefit which many enjoy is the fact that ultrasonic welding leaves behind no seams, which can often be unpleasant to look at. Any welding job performed by an experienced company such as herrmann ultrasonics using ultrasonic welding will leave behind a beautifully bonded piece that has no visual flaws whatsoever.
As with everything in life, there are also disadvantages to ultrasonic welding. One of them is that it is only functional when working with lap joints. It is also limited to the thickness of the joint being worked with. In practical terms, the largest piece the ultrasonic welding is truly functional with would be 250 mm. This is due to the limited power generated by the single transducer.
Regardless, however, ultrasonic welding is still a phenomenal way to join together the parts you need.
