Hot Air Welding Machines for Inflatables

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.

Below are a variety of hot air welding options available, but Miller Weldmaster offers much more, as well as custom designs. To find the exact machine to suit your needs, contact us.


T300 Extreme Curve

Airtight and waterproof seams for the toughest applications

Miller Weldmaster’s T300 Extreme Curve produces airtight and waterproof seams for 2D and 3D inflatables. Discover how the T300 Extreme Curve hot-air and hot-wedge welding machine can help you create seams for uniquely shaped inflatables.

T600 Extreme Curve

Waterproof Seam Welder for Inflatables

This machine produces airtight and waterproof seams for 2D and 3D, meeting the toughest demands with additional fabric handling support. The T600 Extreme Curve is packed with everything needed to weld curves and unique shapes for the production of inflatables, tanks, bladders and more.



SEAM MONITORING for quality assurance

Provide your customer that extra level of comfort knowing their product was monitored for quality inspection. It is a continuous analysis for standard and automation systems that requires non-contact imaging and temperature measurements.


Automated Tank and Bladder Welding Machine

This is designed to increase tank and bladder production while dramatically reducing labor. Our elusively designed welding heads enable the operator to weld overlaps and top and bottom tape covers, all in one pass. The low ground construction enables you to construct your tanks using your floor while eliminating material handling.
