High-frequency welding – the most advanced method currently used for joining polyvinyl chloride (PVC) materials.
When producing products with the new high-frequency welding technology, polyvinyl chloride (PVC) materials are joined using high-frequency current. In the high-frequency welding process, when connecting two or more layers, weld seam deformation is eliminated while providing high strength and flexibility. The weld areas are not exposed to external influences and form a durable joint.
High-frequency current heats the materials from the inside, while the joined materials are pressed between electrodes. This way, welding occurs at the molecular level, ensuring complete airtightness. The mixing of particles between the material layers creates a continuous seam, which is much stronger than the seam formed by hot-air welding.
The accumulated experience and capabilities also provide for the use of other methods in the production of tarpaulin materials. Most commonly, a hot-air welding machine is used. Straight overlap welding is applied for the production of tarpaulins for light and heavy trailers, various canopies, advertising banners, covers, products for non-standard agricultural machinery, and other coverings according to the client’s requirements. In the manufacturing of tarpaulins and other products, a heat gun is used to join parts in areas where it is otherwise impossible.
A hot-air supply workbench is also used in production. It is applied for joining round and curved products and parts to ensure the tightness and strength of seams and joints. The production uses fittings manufactured in Europe as well as certified polyvinyl chloride (PVC) materials, which guarantee their quality and safety.
