SUPRA MAX high frequency welder is designed specifically for use in production of Stretch Ceiling (French Ceiling) interior design elements. The machine is equipped with special high grade welding/cutting electrode to achieve perfect straight line “invisible” seam.
Thanks to the high precision of work, it is possible to obtain rectilinear, aesthetic and very durable welds.
SUPRA high frequency welder has universal application for both: PVC film welding and Harpoon welding with the use of special patented IAW™ Inverted Airplane Wing shape tooling. Cork coated work table allows handling of very thin and delicate films and backlit weld area helps to visually inspect weld precision and quality.
Pneumatically driven welding bar is moved up & down with the use of foot switches allowing the operator both to use both hands for exact material positioning under the electrode, while ZTG SafeDOWN™ anti-crush safety system and pneumatic lock down front gate assures the safe work environment.
The machine can be upgraded (if needed) with additional length work tables for easier film and harpoon positioning during the weld cycle. It can be converted easily into an advertising banner/billboard welder with the use of special wide weld electrode or any other straight bar or spot HF welder.
Full diagnostic testing and certification of the local factory EMC/EMS parameters according to the latest guidelines required by the CE & UL standards. We have our own ISO 17025 certified production control and EMC laboratory providing validation of each required process parameters and the whole technological production cycle.
Traveling Head SUPRA PRO high frequency welder was developed specifically for production of large format Stretch Ceiling (French Ceiling) interior design elements. The machine is equipped with special high precision linear motion gear controlled by frequency inverter to achieve a perfect continuous weld “invisible seam” weld.

High frequency welders manufactured by Zemat Technology Group are designed and built in accordance with current European requirements for machine safety and energy efficiency. The machine design incorporates technical solutions that enhance welding process stability, reduce energy losses, and increase production repeatability.
HF Smart Control™ is a set of structural and electronic solutions implemented in high frequency welders, including:
The HF/RH welders use high frequency generators with microprocessor-based power control, enabling precise adjustment of energy to the process parameters. The system continuously monitors operating conditions and dynamically regulates power in real time. As a result, energy consumption can be reduced compared to heat sealing technologies and many impulse-based systems. The actual level of savings depends on the material, application, and process settings.
The ATS ensures precise impedance matching and automatic generator tuning during machine operation. This stabilizes the welding process, reduces the risk of instability, and minimizes the possibility of arcing. Fast reflected power control protects HF circuit components and improves weld repeatability.
Modern HF generators achieve energy efficiency levels of approximately 70–90%, depending on configuration and operating conditions. Band-pass filters reduce harmonic distortion, while lower thermal losses decrease heating of machine components. This results in stable operation and extended service life of key components.
