Hot Wedge Welding

Leaders in heat sealing technology. . .

Like the Hot Air, Hot Wedge rotary heat sealing is a welding process used to join thermoplastic industrial fabrics and films using a very precise heat speed and pressure. However, in the case of hot wedge welding, a heated wedge is precisely positioned at the weld point providing the required heat. The fabric or film is then pulled across the heated wedge. The tightly controlled temperature of the wedge can range from 700F to 920F (400C to 490C) producing a perfect weld.

Some applications and scenarios one may use the hot wedge instead of hot air: 

• The product to be constructed is made of film.
• There is a need for a quiet work environment. (example: Hot Wedge Tarp Welder )
• The product being constructed is made of a very thin fabric.
