Watertight and Airtight Welding for Curved and Shaped Applications


Miller Weldmaster is a leading creator of hot air welding machines for inflatable tents, military attack boats, 2D or 3D inflatables, and tanks and bladders. Hot air welding allows customers to speed up production to meet demand while ensuring strong, long-lasting seams.

Hot Air Technology

Hot air technology can weld any thermoplastic materials. Most of our customers use hot air technology to weld double-wall or drop-stitch fabrics and PVC-coated and polyurethane (PU)-coated fabrics into products with curves and unique shapes.

With three-dimensional products that need to withstand high impact and high abrasion, seam strength is very important. Certain temperatures will compromise glued seams, but with hot air welding, you get airtight and watertight seams.

Our hot air welders also lower production costs.

"The welded seams of a WING are the strongest part of the boat. We have never had a seam fail. Miller has worked with us from the very beginning. Miller knows that our down time costs money. Miller will go above and beyond what is necessary to help us out."
