Tensile shades and roofing membranes made of polytetrafluoroethylene fabrics (PTFE, Teflon) have become increasingly popular being incorporated into some of the world’s extraordinary architectural designs. PTFE fabric, besides to be UV resistant and not combustible, possess outstanding features such as temperature and chemical resistance as well as dimensional stability and robustness. Diverse types of PTFE are available on the market, also known as glass fabric and silicone coated glass fabrics. None of them could be welded by means of high frequency.
Benefits that can be obtained using the high quality (and rather expensive) PTFE materials in tensile architecture are conditioned with employment of technically advanced equipment, such as special PTFE welding machines. That is reason why Balacchi HF has developed the series of machines for welding of PTFE & silicone coated material. The design of BR10PTFE welding machines involves the big C frame that gives wide space for material handling.
The machine is produced as single-rod (just for heating) or as “double-head” system that enables the welding of PTFE sheets with subsequent cooling of material just underwent the high-temperature sealing. The range offered is widespread: from long welding machine (1000-1800mm) to small welding irons, known as popular hand welding tools.
