Product Description

50mm 4 ceramic chips ultrasonic welding converter plastic assembly

The ultrasonic vibrations are generated in a generator, which converts the incoming mains voltage into high-frequency energy. This high-frequency electrical energy is converted into mechanical vibration energy of identical frequency with the help of the sound converter.

The entire resonance unit consists of generator, converter, amplitude transformation unit and sonotrode, and it works through resonance. In ultrasonic welding, the heat required to melt the moulds is created by converting ultrasonic vibrations into mechanical vibrations and guided to the work piece to be welded at a certain contact pressure through the sonotrode. The plastic components function here as the energy carriers.

The mechanical vibrations occurring on the work piece are absorbed and reflected away at the boundary. Heat that melts the plastic is generated on account the boundary- and molecular friction. The dense vapour-emitting plastic layer creates a sound blockade, which leads to additional melting of the plastic and hence, to an acceleration of the reaction.

In ultrasonic welding, there are three variables to consider: time, pressure and amplitude. All three need to be taken into consideration to control the process. But before we can delve into these considerations, we need to understand the main components of this type of welding. Ultrasonic welding equipment consists of a machine press, generator, converter or transducer, sonotrode or horn, component support tooling and booster.

ultrasonic-welders

Back in the 1960s, ultrasonic welding took plastic assembly to a new level. It helped to optimize design and productivity in a wide range of industries, from automobiles to cosmetics. The quality and speed of ultrasonic welding were unlike any other process, transforming plastic assembly into a more reliable, highly efficient operation.

The first industry to take advantage of this reliable welding technology was the toy business. Pioneered by Mattel and Knickerbocker, ultrasonic welding was the technology behind numerous popular toys. Later, automotive companies jumped on the bandwagon.

General Motors, for example, used ultrasonic welding for turn signals and tail lights. By the early 1970s, ultrasonic welding was applied to different medical applications. Today, ultrasonic welding is used in many applications, including cell phone casings and electronic products. Ultrasonic welding is now considered the leading assembly method for rigid thermoplastics.
