What is HF welding machine?

Jul. 30, 2018

Principle of HF welding machine.High Frequency (HF) or Radio Frequency (RF) welding is the joining of materials by providing HF energy in the kind of an electromagnetic field (27.12 MHz) and strain into the material surfaces to be combined. A generator produces the energy. The tool used to supply the energy is known as an electrode. The electric energy leads to the molecules inside the material to start moving, which creates heat that causes the material to soften and thereby fuse together. No outside heat is used. It's instead generated inside the material. After cooling the welded surface under preserved pressure, the material is fused and a weld was created. The weld seam may be at least as powerful as the surrounding substance -- or even more powerful.

Four important factors profile welding machine impact the final weld outcome are welding, pressure effect, welding time and cooling time. These parameters could be adjusted and combined in various ways to accomplish the optimal welding result for a particular material.

Belt Cutting machine most commonly used with HF welding is PVC (polyvinyl chloride), sometimes called vinyl and PU (Polyurethane). The substance can be thick or thin, reinforced or coated. It can also be plain, coloured or patterned.
