Create Industrial Seams with Hot Wedge Welding

Hot wedge rotary heat sealing is a welding process using very precise heat, speed and pressure to join thermoplastic industrial fabrics, textiles and films.

During the hot wedge welding or seaming process, a heated wedge is precisely positioned at the weld point to provide the required heat. The fabric or film is then pulled across the heated wedge. Tightly controlled temperature of the wedge can range from 700°F to 1350°F (400°C to 750°C) producing a perfect weld.

Why Choose Hot Wedge Welding
  • Producing a product made of film
  • Constructing a product made of very thick fabric
  • Creating straight or radius welds
  • Creating a quiet work environment
  • Create seams that are stronger than the material itself for diverse manufacturing jobs
  • Create airtight and waterproof seams unlike when you sew and are poking holes in the fabric
Is Hot Wedge the Right Technology for My Application

To ensure our customers have the best heat system for their application, it is best to speak with a Miller Weldmaster expert. While hot air, hot wedge, impulse and RF work for many applications, one may work better than the other depending on the application. Miller Weldmaster will help you select the best technology for your application.
