High Frequency

Home / Servizi / High Frequency

This particular technique allows you to weld, couple, or create relief on the processed material.

Its peculiarity is the excellent mechanical resistance given to the part that, within a few seconds, thanks to an electromagnetic field applied by special machines, is melted and re-welded at a molecular level.

High frequency uses high-frequency waves that are passed through the small area between the mold and the table where the work is done; this creates a high-frequency electromagnetic field that oscillates the molecules of some types of materials that heat up to their melting point.

The combination of this “heat” and the pressure make the welding take the shape of the mold.

This process makes high frequency useful in a variety of sectors where a strong and constant endurance is required. The only limit is that it can only be used with materials where the molecules can vibrate due to the alternating electric field, so PVC (polyvinylchloride) and PU (polyurethane) are the most common thermoplastics to be welded with HF, however, it is also possible to weld other polymers such as nylon, PET, EVA, and some ABS plastic materials.

Another great advantage of HF is its speed: since the material is warmed from the inside to the outside, the melting happens very quickly, often in just a few seconds.

The welding tool can be engraved to give a personal decorative look to the product. A cutting edge can be added next to the welding area, allowing the machine to perform simultaneous cutting and welding operations and then evacuate the fabric waste part.

New Press performs High Frequency processing on synthetic materials such as:

  • Lycra
  • Neoprene
  • PVC
  • PU
  • TPU
