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 welding is using a high-frequency current to generate heat, liquidate (melt) the plastic material together with the pressure to weld the materials completely, high cycle and then stop, after a period of time to cool so that the products cure, high frequency welding process is complete.
In general, bonding or embossed material is placed in the middle of two electrodes, the upper electrodes, which is the mould shape according to the desire welding shape of the produce, the lower electrode is a fixed metal plate, a layer of aluminum or copper will be covering the product, The shape of lower plates is also made based on the shape of products.
