Introduction
High-frequency welding (also known as radio frequency (RF) welding or dielectric welding) is a process that uses high-frequency electromagnetic waves to generate heat and bond materials together. This technique is primarily used for thermoplastic materials, where the application of high-frequency energy causes the molecules in the materials to vibrate and generate heat, resulting in a strong, uniform weld.
HF welding machines are essential tools in industries that require strong, durable bonds in thermoplastic materials. Their ability to produce clean, consistent welds quickly and efficiently makes them invaluable for high-volume production.
High Frequency Welder Features
Welding Length: up to 30m

How High-Frequency Welding Works
Preparation:
The materials to be welded are placed between two electrodes.
These materials are typically thermoplastics such as PVC, polyurethane, and certain types of rubber.
Application of High-Frequency Energy:
High-frequency electromagnetic waves (typically in the range of 13.56 MHz to 27.12 MHz) are applied.
The energy causes the molecules in the plastic to vibrate, generating heat.
Pressure:
Pressure is applied by the electrodes to press the materials together.
This pressure helps to ensure a uniform weld and expels any air or gas trapped between the materials.
Cooling:
Once the materials reach the necessary temperature and have been pressed together for sufficient time, the high-frequency energy is turned off.
The materials are allowed to cool under pressure, forming a strong bond.
