Ultrasonic Spot Welding Machine:

Ultrasonic plastics assembly is the joining or reforming of ther- moplastics through the use of heat generated from high frequency mechanical motion. It is accomplished by converting electrical energy into high frequency mechanical motion (vibrations) that creates frictional heat at the joint area. The vibrations, when applied to a part under pressure/force, create frictional heat at the interface and cause the plastic in the joint area to melt, creating a molecular bond between the plastic components.

Most people are familiar with what happens when a metal object is repeatedly struck with a hammer. If the impact is hard enough and occurs often enough, the metal object begins to get warm. If this beating action continues, the metal can become surprisingly hot. The metal object gets hot because its molecules are moving, or vibrating, at a rate that causes an increase in temperature.

According to the basic laws of physics, the true definition of heat is a the energy associated with the random motions or vibrations of molecules.a Theoretically, only at absolute zero (calculated to be
-273 degrees C and probably impossible to achieve) does molecular motion cease. So, in practice, the molecules of any substance are constantly vibrating. The amount of molecular vibration in a sub- stance determines its temperature. The more its molecules vibrate, the a hottera a substance is. In the example above, the impact of the hammer causes the molecular vibration in the metal to increase and accounts for the rise in temperature. By focusing high frequency sound vibrations to a specific area of a thermoplastic, the materiala s molecules are a shaken upa and the temperature increases until the material melts and either bonds to the adjoining part (welding) or takes the shape of the tool
