High frequency welding machine for soft pvc bag

High frequency welding machine for soft PVC bag(Rf Pvc Bag Sealing Machine) is main to do kinds of flat bag ,raincoat ,trademark ,inflatble valve ,soft PVC or TPU bag etc products. Machine Principle: High Frequency welding machine is using the high frequency electromagnetic waves to heat and soften the join of certain plastics which have chemical dipoles, such as PVC, PA and acetates. When a press/die descents to apply pressure on the surface of two pieces of material, the high frequency wave are passed through the die and table. The high frequency field causes the molecule to vibrate and generate heat from vibration. The process can be continuous and able to perform localized heating.   The Characteristics of the Hf Pvc Welding machine : (1).adopt the vacuum tube, the output power is stable and reliable. (2).high sensitive spark over-current protection circuit. Can effectively cut off because of the large current output damage the host…
