What is HF welding tube process ?

High Frequency Welding, known as Radio Frequency (RF) or Dielectric welding, is the process of fusing materials together by applying radio frequency energy to the area to be joined. The resulting weld can be as strong as the original materials. HF Welding relies on certain properties of the material being welded to cause the generation of heat in a rapidly alternating electric field. This means that only certain materials can be welded using this technique. The process involves subjecting the parts to be joined to a high frequency (most often 27.12MHz) electromagnetic field, which is normally applied between two metal bars. These bars also act as pressure applicators during heating and cooling. The dynamic electric field causes the molecules in polar thermoplastics to oscillate. Depending on their geometry and dipole moment, these molecules may translate some of this oscillatory motion into thermal energy and cause heating of the material. A measure of this interaction is the loss factor, which is temperature and frequency dependent.

And then to the sizing system to finish the whole process.
