High Frequency Welding Machine Auto Feeder type
What is High Frequency Welding?
High frequency welding is the high-frequency energy delivered to the thermoplastic plastic placed between two electrodes. Thermoplastic plastics can be constituted by two or three and more layers. The shape of upper electrode (mold) is made accordant to the desire embossing or welding shape on the plastic, and the lower electrode could be the shape of product appearance or just a piece of metal plate. The electrode is usually connected to the hydraulic or pneumatic cylinder, in order to apply pressure when welding.
High-frequency provide a local heat through the excitation of molecular materials to 27MHz, resulting in melting material, and mixture the material elements together, then put pressure above the material, bringing a complete fusion. Then stop applying the high-frequency current, the brief cooling enhance the material solidification, materials are welded at the point of contact with die. The strength of the material is stronger than the original after high frequency welding.
