RFlex Radio Frequency Welding Machine

The Most Versatile Radio Frequency Machine

The RFlex stationary welder is the industry’s most versatile radio frequency welder available on the market. RFlex was designed for the production of tarpaulins, tents, truck tarps, high speed doors, and any other flexible Polyvinyl chloride (PVC) or Polyurethanes (PU) product. With enhanced features such as, a foldable trough for better material handling, a joy stick to accurately line up your material every time, autotuning for consistent welds, your production will be even more efficient and reliable.

How does Radio Frequency Work?

Radio Frequency (RF), also known as High Frequency (HF) or Dielectric welding, is the process of fusing materials together by applying radio frequency energy to the area to be joined. The heating process in the RF sealing occurs from the inside out.

You have the option to have a back table or to fold it down for an a deep space where your material can feed down behind the electrode for more efficient and easier material handling.


With standard and custom dies available, you have the ability to create an endless number of seam types on the RFlex you need. Give us the desired shape of die you need, and we will design it for you.




  • Simple to setup and easy to operate
  • Universal usage for PVC, PU, TPU, reinforced technical textiles
  • Foldable large worktable with deep trough creating ample space behind the electrode for easy material handling
  • New generation stable and efficient RF power generator
  • Easily change dies with QuickGRIP release system of the electrodes
  • Easier material placement and better visualization of weld with built in LED illumination.
  • Manual, semi-automatic and automatic operation
  • 10″ touch screen HMI panel on a swing arm for use on any side of the machine
  • MW safeDOWN anti-crush electrode safety motion system
  • Fully automated weld cycles with 100 weld cycle recipe memory
  • Auto-tuning for steady RF power feed to assure consistent welds
  • High production capacity with fully programmable PLC
  • RF emission protection.
  • Custom dies available for versatile production
  • Line up your material accurately every time with the joystick and foot pedal precision
  • Easy to use intuitive operating menu with machine specific software
  • Ultrafast monitoring of arcs and overloads for protecting the integrity of the electrodes and the welded material
  • For welding non-RF weldable fabrics, the RFlex can be fitted with an impulse electrode

Advanced technology = less power(kw) needed!

The RFlex is designed to cover a large range of power output configurations with the use of our exclusive RF auto-tuning system. The RFlex welder at its core is a 15kw RF powered machine. However, our efficient eco-RF machine will perform as a 17kw-22kw welder. The RFlex allows you to weld up to 100in² of linear configuration.

Use our kw calculator to determine your required power requirements based upon your area to weld.


Welding Experience
