High Frequency PVC Welding Machine

High frequency welding (often abbreviated HF welding or RF welding) is a manufacturing process where two plastic parts are welded together using an electromagnetic field. The resulting join can be very strong – often close to the original strength of the materials joined.High frequency induction welding is used to make pipe or tube from strip which is fed into rolls which form the strip into a cylindrical shape. The faying edges are brought together between squeeze rolls to produce a V at the point of welding, with an included angle of typically 2-5° for steel.
