Welding Machine Manufactures
Hot Air Welding
Air heated to over 400° F is directed through a nozzle precisely into the space between the fabrics to be joined. The heated surfaces are then pressed together by a roller which follows the nozzle.

Leister

Electronic Welding
Thermoplastic vinyl molecules are excited (heated) by radio frequency waves. The materials are pressed together between a sealing bar and a bed plate.

Forsstrom
Hall Dielectric
JTE Machine Systems
Impulse Welding
Asco
Novaseal
Miller Weldmaster
Wedge Welding
Fabrics pass between spaces above and below a heated metal wedge as it is moved along the materials to be joined. The resulting heated materials are then pressed together by a trailing roller.

The Welding Process
The “V” in PVC is for Vinyl. PVC (polyvinyl chloride) is a versatile polymeric plastic that is strong, flexible, and weather resistant, and it has an attractive finish for fabrics used in signs, banners, tents, transportation, and many other applications. PVC is a “thermoplastic” which means that it is highly suitable for welding.
