Davison-machinery Introduction High Frequency plastic welding is also called medium fusion

Davison is experienced in designing, manufacturing, and selling High Frequency Welding Machine, RF Welding Machine, PVC Welding Machine, High Frequency Welding.

High Frequency PVC Welding Machine 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.

High Frequency plastic welding is also called medium fusion. High frequency welding is relying on some property of the plastic, heating plastic products in a rapidly alternating high-frequency electric field. That is placing plastic material with high dissipation factor in the high frequency electric field, heat up and weld the products. The High-frequency processing method is usually placing the application in the High-frequency electromagnetic field. Which is placing them between two electrodes. The lower electrode is usually made with iron or aluminum and the upper electrode is so-called high frequency mold made accordant to welding length, range or shape of embossing patterns.

PVC and PU is the most common thermoplastic HF Welding Machine material. High frequency welding can also apply on other machine application such as polymers, including nylon (Nylon), EVA, PEVA, PET, PETG, APET and some ABS resin. Nylon (Nylon) and PET require using electric equipment together with warm-frequency welding machine to enable processing.
