What is high frequency (HF)

High frequency welding is a very effective and resistant welding technique which consists of stressing the very molecules of the parts of material which are to be joined and does so without the use of heat sources. It is the electrical impulse used that brings the parts together, forming a kind of "new material" that has the same characteristics as the original one. It is used in various sectors. We have been manufacturing machinery using this technology for 50 years in various industries.
