Hansweld WELD-H High Frequency Welding Machine – Industrial HF / Radio Frequency Welding for Oversized Tarpaulins and Geomembranes
The Hanswend WELD-H is a robust HIGH FREQUENCY WELDING MACHINE designed for heavy‑duty PVC welding. Operating at 27.12 MHz, it delivers strong, airtight, and watertight seams for extra‑large TARPAULIN and GEOMEMBRANE production.
Its suspended welding head design frees the machine from fixed‑frame limitations, enabling continuous welding of oversized materials. This makes the WELD-H ideal for large‑format applications, including:
Truck tarpaulins & side curtains
PVC biogas digesters & water reservoirs
Geomembranes for landfill liners & pond liners
Inflatable boats, children’s swimming pools & bouncy castles
Tensile membrane structures, awnings, tents & outdoor shades
Industrial covers, billboards & advertising banners
Equipped with a cross‑line laser positioning guide, roller bars for smooth material feeding, and an NL‑5557 spark protection system, the WELD-H ensures precise alignment and protects both mold and product. Available with power options from 15 kW to 35 kW and CE certification, this HF WELDING (also known as RADIO FREQUENCY WELDING) solution is built for large‑scale, continuous industrial production.
