SM-321 | Multiple tool conveyor welding machine

The SM-321-HA is a digitally controlled multiple-tool welding station with conveyor belt for the full-automatic and continuous production of truck curtains, anti-vandalism curtains, and truck roofs. The culmination of more than a decade of experience in designing and building heavy duty welding and cutting machines to process PVC-coated textiles, the SM-321-HA is a game changer in the truck curtain industry.

The SM-321-HA drastically reduces the time needed to manufacture a truck curtain from several man hours to 20 minutes or less. Since its introduction in 2010 the machine has seen continuous upgrades and, today, is an extremely efficient, very precise manufacturing solution for quality truck curtains.

The SM-321-HA can manufacture directly from the jumbo roll or process individual pre-printed or pre-cut PVC panels and enables manufacturers to produce curtains and roofs of superior quality. With specifically developed easy-to-use software programs, no particular skills are needed to operate this machine.
