RF & HF welding better than hot air, gas & wedge welding

There are at least 10 ways of joining the synthetic fabrics (mainly plastic). The most popular methods are high frequency, hot air and hot wedge welding. With the chart below, we want show you why the high frequency welding is the most convenient, and therefore, the best method available.

	HIGH FREQUENCY (HF)	HOT AIR	HOT WEDGE
TYPE OF FABRICS	PVC, PU, ETFE, PTFE	PE, thin PVC foils
WELDING TECHNIQUE	The heat is generated inside the welded fabrics by providing high frequency voltage by means of metal electrodes. This makes the layers of fabrics melt and fuse together.	The heat is provided by the tool (hot air jet)/ (hot wedge) to the welded surfaces from the outside. The weld is formed on the surface of the joined fabrics.
WELDING SPEED AND TIME	HF welding technique is the most efficient in speed and time within one welding cycle. HF makes the layers of fabrics heat up evenly at the same time, no matter how thick they are. The cooling time is also quicker and supported by air or oil cooling systems.	The welding speed and time depends on the thickness of fabrics to be welded. The thicker the layer is, the longer it takes to heat up the surface to the required temperature. The risk of overheating the fabrics is very high in this case. The cooling time depends on the fabrics characteristics.
QUALITY OF THE WELD	Weld strength equals the strength of welded fabrics. The weld is also uniform and very flexible. No smoke or unpleasant smells appear.	The weld is formed on the surface of the fabrics what makes it less durable. It is also less flexible due to hard seam produced during welding. The welded fabrics can produce smoke, drippings and unpleasant smell.
APPLICATION	HF welding can be applied in various industries such as advertising, light architecture, automotive; the size of both production and final products is insignificant.	These techniques can be applied in various industries: advertising, light architecture. Used mainly for repair jobs (operated manually in this case).
