Hot Air / Wedge Welding

Hot air rotary heat sealing is a welding process used to join thermoplastic industrial fabrics and films using very precise heat, speed and pressure settings. The correct combination of these three parameters allows one to achieve a complete weld. In the case of hot air, heat is provided by compressed air blowing across electrical heat elements and is injected at the welding point. The tightly controlled temperature can range from 1000Fto 1,3500F (400C to 7500C).
