High-frequency welding
This technique applies to plastic materials in the form of single, semi-rigid or rigid sheets. Thermoplastics such as phthalate-free PVC, TPU and EVA are the most commonly used. High-frequency weldingjoins two or more sheets together by applying an electromagnetic field. The zone reproduces the shape of the tooling called an electrode.
The high-frequency welding method depends on :
- Type of material
- Product shape
- Product dimensions
- The number of sheets to be assembled
Advantages of high-frequency welding
- High mechanical strength of the weld
- Complex shapes
- Possibility of combining a flexible container with a thermoformed product
- Rapid prototyping
- Custom design
- High speeds
- Moderate tooling costs
