There are other technologies than high frequency (radio frequency) welding which can be used to join together sheets of PVC and PU materials.
So, why use high frequency (HF) rather than other technologies?
HF-welding is by far the best method for joining PVC and PU materials. The weld is much stronger, compared to other technologies, such as hot air, hot wedge or impulse welding. The resulting weld is also airtight and waterproof. Thats why HF/RF.
Advantages of HF-welding
- Repeatable, reliable technology
- Strong, durable and even welds
- Air, gas and waterproof welds
- Multi-layer welding
- An environmentally friendly choice
Apart from HF there are other technologies for joining material, such as:
