What is HF welding machine or RF welding?
High Frequency (HF) or Radio Frequency (RF) welding is a technique used to join thermoplastic materials. It employs radio waves and pressure to create strong, high-quality welds. Operating at 27.12 MHz, this process uses electromagnetic energy to generate heat within the materials being joined.
How does HF welding or RF welding work?
HF welding involves a few key steps: ① Energy Generation: A generator produces HF energy. ② Energy Application: An electrode tool delivers this energy to the material surfaces. ③Heat Generation: The energy causes the molecules within the material to move, generating heat internally. ④ Material Softening: This internal heat softens the material, allowing it to fuse. ⑤Cooling Under Pressure: As the material cools under pressure, a strong, durable weld is formed. Unlike other welding methods, HF welding does not require an external heat source. The heat is generated within the material itself, leading to weld seams that are often as strong or stronger than the surrounding material.
Why use high frequency or radio frequency?
HF-welding is by far the best method for joining PVC and PU materials. The weld is much stronger, compared to other technologies, such as hot air, hot wedge or impulse welding. The resulting weld is also airtight and waterproof.
