  Advantages of ultrasonic welding: Ultrasonic welding has many advantages when compared to traditional welding technologies. Many industries use ultrasonic welding due to these specific combinations of merits. Does not need external heat source: The primary advantage of ultrasonic welding is that it doesn’t need an external heat source. The heat is self-generated between the materials. Fast:...

  Ultrasonic plastic welding is the joining or reforming of thermoplastics through the use of heat generated from high-frequency mechanical motion. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied force, creates frictional heat at the plastic components’ mating surfaces (joint area) so the plast...

  There are many advantages to using ultrasonic assembly. It is a fast, clean, efficient, and repeatable process that produces strong, integral bonds while consuming very little energy. No solvents, adhesives, mechanical fasteners or external heat are required. Finished assemblies are strong and clean. Difficult materials can be assembled ultrasonically. Part assemblies are cycled quickly bec...

  Ultrasonic welding has many advantages over traditional methods. For one, welding occurs at low temperatures relative to other methods. So, the manufacturer does not need to expend vast amounts of fuel or other energy to reach high temperatures. This makes the process cheaper. It's also faster and safer.   The process occurs in fractions of a second to seconds. So, it can be done more ...

  Look at a pair of athletic shoes. While traditional shoes may be made of a single material such as canvas or suede leather, many athletic shoes have several materials such as lightweight plastic polymers, suede or synthetic suede, and mesh combined. These composite materials make the shoes light, flexible, durable and breathable. For example, one style of New Balance athletic shoe has an up...

  The basic process of ultrasonic welding can be described by the following steps:   The parts to be welded are placed in the anvil or fixture. The horn contacts the parts to be welded. Pressure is applied to keep the horn in contact with the welded materials and to hold them together. The horn delivers ultrasonic vibrations to heat up the materials. The vibrations move less than a milli...

  Rub your hands together rapidly. Notice anything? They warmed up, right? If you take a hammer and pound a metal surface rapidly and repeatedly, you will find that the place where the hammer strikes the metal warms up, too. In both these examples, the heat is due to friction. Now imagine rubbing your hands or pounding that hammer thousands of times per second. The frictional heat generated c...

  General description The ultrasonic welding technology for plastics is considered part of the melt welding processes. The process is based on a conversion of friction and vibration energy into heat. Using a welding tool called a sonotrode, the high-frequency vibrations generated by the ultrasonic system, in combination with pressure, are transferred to the parts to be joined, which leads to ...
