What materials are most commonly welded with high frequency?

High frequency welding is one of the most effective methods of joining thermoplastic materials. This technology uses high frequency electromagnetic waves that cause molecules in the material structure to move, generate heat and allow fusion. This process is mainly used for materials with polar properties that effectively conduct energy.

PVC – the most commonly used material

Polyvinyl chloride (PVC) is one of the most popular materials welded with high frequency. Thanks to its polar structure and dielectric properties, this material is ideal for this process. PVC is used in the production of a wide range of products, such as covers, shower curtains, tarpaulins and medical devices, such as blood bags. This material makes it possible to quickly create durable and tight joints.

PVC-coated material – technical textiles and tarpaulins

Technical textiles coated with a layer of PVC are another group of materials often welded with high frequency. They are used to produce tarpaulins, tents, conveyor belts and protective covers.

Use in various sectors

Materials suitable for high frequency welding are used across numerous industries. The medical industry uses this technology to produce packaging for medication, rehabilitation equipment and protective clothing. The automotive industry uses it to produce sun shades and car mats. In the entertainment industry high frequency machines are used to produce inflatable attractions, and the military sector uses it to manufacture tents and bulletproof vests.

Why use high frequency welding?

This method is characterised by speed and precision, which allows for increased production efficiency. The joints created are very durable and resistant to humidity, UV radiation and other external influences. The process is also environmentally friendly, as it does not produce any harmful emissions or noise. This is why high frequency machines are widely used in many industries.
