Create Industrial Seams with Hot Wedge Welding Technology

Hot wedge rotary heat sealing, or hot wedge welding, is a precise welding process that uses specific heat, speed, and pressure to join thermoplastic industrial fabrics, textiles, and films. Hot wedge welding machine uses range from industrial fabric joining to large-scale film welding.

During the hot wedge welding machine process, a heated wedge is accurately positioned at the weld point to provide the necessary heat. The fabric or film is then drawn across the heated wedge. Tightly regulated temperature of the wedge varies from 700°F to 1350°F (400°C to 750°C), ensuring a flawless weld.

Why Choose Hot Wedge Welding Machines

  • 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

Welding Wedges

Depending on your seam size, there are countless wedge sizes to match.  It is important to use the correct size wedge and rollers to produce the best weld possible.  Along with the weld rollers, the proper-sized wedge provides the correct amount of heat to the exact area needed.  This provides an accurately sized weld with the pressure to create a strong weld as well.  If you use a smaller hot wedge, the seam will be weak on the edges as there is not enough heat applied evenly across the seam.  On the other hand, if you use too big of a hot wedge, the seam will be messy as there is more heat than needed.  Heat will be applied but no pressure since the weld rollers will not match.

Heat, speed, and pressure are vital components in producing the strongest and cleanest weld. Hot wedge welding machine technology excels in creating long straight seams for products like Signs, Banners, doors and more.

Industries that benefit from hot wedge welding machines include Sign, Pool, Shades, Tent, Awning, Aerospace, Curtains, Roller Doors, Filtration, Geomembranes/liners.

Products made with hot wedge welding machine technology include Containment Booms, Curtains, Roller Doors, Pool Covers & Liners, Keder, Shelters, Tents, and Awnings.

 Wedge Welding For HDPE

Miller Weldmaster has numerous machines for countless Hot Wedge applications.  From the portable Triad or Spec to help with finishing your signs and banners, to the versatile T300 and T600 that can be used for larger products.  

Hot wedge welding machine technology is frequently used for long, straight seams. High-Density PE, a material Miller Weldmaster customers frequently use to produce geomembrane liners, is a resistant cover often used in landfills, pond linings, water containment areas, and more. Large HDPE panels are welded using hot wedge technology, making the process efficient and reliable.

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.
