How does radio frequency welding (or HF) welding work?
High Frequency Welding, known as Radio Frequency (RF) 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.
Who Uses RF Welding?
There is a wide variety of products that are made with Radio Frequency Welding. Some examples would be tensile structures, tents, swimming pool liners, high speed rolling doors, oil booms, billboards, and many more. To see which machine best fits your industry, click here.
What Materials Can Be RF Welded?
All thermoplastic materials that contain polarized molecules. Polyvinylchloride (PVC) and polyurethanes (PU) are the most common thermoplastics to be welded by the RF process. No matter the thickness, color, pattern, coated vs. noncoated it can be welded with RF technology. Materials that can be RF welded include:
Where is Radio Frequency Used:
Radio Frequency welding is used in multiple industries that create straight and unique shaped products. From consistent straight welds like tarpaulins, high speed rolling doors, and billboards to unique shapes such as oil booms, tent peaks, water tanks, and more. Many companies require multiple technologies for different seams in their process. Contact usto help determine which technology is right one for your product.
When to choose RF:
Choosing the right sealing technology depends on your material, the product size and configuration, and the amount of production required. Radio frequency creates consistent clean looking seams without any mess of adhesives or solvent. If you are consistently making the same product that requires a unique shape weld, radio frequency is the right welding technology for you. RF technology also allows you to hit the same area of the weld more than once, where other technologies do not.

Why choose radio frequency welding:
Creates airtight and waterproof seams unlike when you sew and are poking holes into the fabric
Weld the same area more than once with no damage to the fabric
Specialized dies are made available for intricate welds
Seams that are stronger than the material itself for diverse manufacturing jobs
The RFlex stationary welder is the industry’s most versatile radio frequency welder available on the market.
The most advanced technology
Endless weld types available with ability to make any custom die
New machine frame designed for improved material handling
Automated Traveling RF Welder
The RFlex Travel is a radio frequency welder that is designed for the production of tarpaulins, tents, truck tarps, high speed doors, and any other flexible Polyvinyl chloride (PVC) or Polyurethanes (PU) product. Line up your material with the lasers on the track, let the vacuum work table hold your material in place, press a button, and let the travel head do the welding for you. Reliable and effortless production.
