IMPLA HF welder heat sealer is designed specifically for production of small and large format tensile structures, membranes, tarpaulin, tents, oil booms, truck covers, swimming pool liners & covers, airline hangars, large billboards, fast doors, side curtains, etc. This basic design machine can be fitted with special impulse electrode for welding non-HF weldable fabrics made of PE and PP, as well as FlexEL 'soft' multilayer welding electrode and curved HF electrodes for sealing round window profiles made of clear PVC and any other shapes requiring precision welding.

SIMPLA model is equipped with special deep and wide trough behind the electrode for material storage and handling. Machine has optional smooth glide wheels for easy movement in-around welded fabric, or relocation to a desired place in manufacturing hall.

Full advanced programming functionality, including ATS™ auto-tuning and WCS™ systems is achieved thanks to onboard PLC integrated with 10" touch screen HMI on a Swing Arm for easy access to welding area. SIMPLA machines have HF power outputs from 10 kW to 15 kW for heavier production loads and reinforced heavy duty fabrics, effectively providing between 240-800cm2 of welded surface with one weld cycle.

Simpla 2i

simpla 2i

SIMPLA 2i is the first and only universal RF bar Welder/Sealer on the market with full DOUBLE functionality: Radio Frequency welding and Impulse Heat Sealing. It has an universal usage for PVC, PU, PE, PP, TPU, reinforced technical textiles and films, Acrylics and Nylons. No other welding machine in the world today gives so much flexibility with easy tool change and fast conversion from a standard RF welder into a double bar (upper/lower) Impulse Heat Welder.

Simpla Crystal

simpla crystal

SIMPLA CRYSTAL HF welder was created for the production of CRYSTAL Clear PVC windows with Invisible Seam technology. The machine can also handle the demanding production requirements for Pergolas with "omega" profiles and zips, awnings, shadings and other small and large format tensile structures, side curtains and membranes.

With the use of special tools' set the SIMPLA CRYSTAL HF welder creates a strong very thin (1.0 mm) linear weld to join Crystal Clear PVC film. Machine is equipped with sliding 3200 or 4500mm long weld table for very precise linear welding (± 0,1mm) from end to end. Front and back table troughs provide ample storage for rolled film during production process, while special deep and wide trough behind the electrode for excess material storage and handling is very useful when working with pergolas, awnings or membranes.
