High frequency welding (HF High Frequency)----
The assembly is made by highfrequency and pressure between twoelectrodes, which have the final productshape. It is a proven and
very common industrial and mass produc- tion technology.It remains as of today the most economicaltechnology on the market.
Heat Bonding (HB - Heat Bonding or Over-lap)----
The assembly is made with a flow ofvery hot air and pres- sure atthe 2 PVCsheets overlapping area. It is a hand-madetechnique combining craftsmanship
and welding experience with high tech machines.We offer a wide range of Single, Double,In-Line, Triple tubes to meet growing demand from our customers.
Gluing----
Under the certain temperature andhumidity, with some special glue, which iswaterproof and last long, the seam is overlapped by some forces applied. It comes
