What is RF Welding? RF Welding refers to the process of bonding materials together through the use of electromagnetic energy. While RF does involve the heating up of molecules within materials, there is no external heat source applied topically to the material. Materials that are commonly RF welded include PET, PETG, PVC, Thermoplastic Polyurethanes, Open Celled Polyurethanes, and LDPE/EVA. Today there are only a handful of manufacturers based in the U.S., with JTE leading the way in providing advanced controls for all of its RF machines, with a specialization in automation and integrated cutting operations.

Many people may be familiar with the phrase “RF Welding” but are unsure as to what it really means. RF (radio frequency) welding, also known as HF or high-frequency welding, refers to the process of bonding materials together through the use of electromagnetic energy. This process creates an oscillating electric field that shifts and moves polar molecules within the materials between a tool and the platen. When these molecules move, they release energy in the form of heat. When enough of this energy is applied, the molecules begin to melt and bond to one another. The weld is completed by applying pressure to the bonded area, ensuring a successful seal without any external heat.
What Factors Influence a Good Weld?
There are many factors that affect the strength and quality of a seal in RF welding. Some of the most important factors in creating a good seal include tooling layout, weld thickness, and machine control. All RF welds require adjustments in the power level, pressure level, and time for both weld and cooling settings. The best RF weld results from machines that control the power, pressure, and time precisely throughout the welding cycle. The appeal of RF welding lies in the completeness of the weld that it provides. When you choose RF welding as your method, you can create very robust hermetic seals. These seals are airtight, as many welds are subject to peel tests, leak tests, and optical tests to determine whether or not the correct conditions have been achieved.
What Materials Can Be Welded?
Here is a list of the most common materials the RF welding is performed on:
Is RF the same as Heat Sealing?
While many people, including some RF machine manufacturers, refer to their RF machines as “Heat Sealers”, the term is inaccurate when explaining RF technology. Heat sealing is the process of sealing one thermoplastic to another similar thermoplastic using heat and pressure. The direct contact method of heat sealing utilizes a constantly heated die or sealing bar to apply heat to a specific contact area or path to seal or weld the thermoplastics together. While RF does involve the heating up of molecules within materials, there is no external heat source applied topically to the material. In fact, the RF tool is usually regulated to maintain the same temperature as the ambient temperature or just slightly warmer to produce the most efficient RF weld.
History of RF Welding for Plastic Materials
RF (HF) welding can also be referred to as dielectric welding, and is a relatively mature technology with regard to welding plastics. It has been around for over 50 years, starting in Europe, as a result of theoretical knowledge of the first radar systems and post-war experience accrued in the field of inductive and capacitive heating of materials. Today there are only a handful of manufacturers based in the U.S., with JTE leading the way in providing advanced controls for all of its RF machines, with a specialization in automation and conversion of existing sewing operations.
If your machine is not as efficient as you would like, your welder may not be the right machine for the job. Our eBook 5 Signs That You May Be Using the Wrong Fabric Welder can help you figure out the answer to this question, and help you find the machine that fits your welding needs.

Dynamic Cutting Solutions
One of the first machines to showcase the marriage of automation and fabric welding is the multifunction cutter. The multifunction cutter is an automatic flatbed or conveyor cutting machine that is specially designed for cutting and marking flexible materials, and can be used by the awnings, inflatable, industrial door, and tensile structures industries, just to name a few. Some of its technical features include:
Advantages of Automation
When it comes to the introduction of automation into the fabric welding industry, the advantages are endless. Not only does automation increase overall efficiency in the workplace, but the sturdy design and durability of the frame and bridge of the multifunction cutter ensures that there is square-ness to the cut and no flexing, which increases the life of the machine. This, in turn, decreases the cost of ownership, as repairs and machine upgrades are not as common. The machine also comes with a precision-driven rotary cutting tool, which reduces the wear of the cutting surface, while increasing accuracy and optimizing joints. All JTE machines come with cutting edge software that is application specific to further increase overall efficiency.
Advantages of One Partner
When you are considering the implementation of automation within your industrial fabrics manufacturing, you no longer have to seek out multiple companies.

Radio Frequency (RF) welding is a process that uses electromagnetic energy to bond materials. Also known as High Frequency (HF) welding, this process creates an oscillating electric field that shifts and moves polar molecules within the materials between a tool and the platen. The movement of these molecules releases energy in heat form. When enough energy is applied, the molecules begin to melt and bond. Pressure is then applied to the bonded area completing the weld.
One of the most important aspects of RF welding is creating a seal that is strong and of consistent quality. The most important factors when creating a seal include:
To ensure you have the best RF welds, use machines that control the power, pressure and time throughout the welding cycle. It is important to note that all RF welds require some adjustment, usually in the pressure level, power level, or in the time needed for the weld and cooling settings.
The History of RF Welding
In addition to HF welding, RF welding can also be referred to as dielectric welding and has been around for over 50 years. RF welding began in Europe as a result of theoretical knowledge of the first radar systems and post-war experience of heating materials. Today there are only a handful of U.S. based manufacturers like JTE leading the way in providing advanced controls for all of its RF machines, specializing in automation and the conversion of existing sewing operations.
Why Use RF Welding?
The appeal of RF welding lies in the complete weld that it provides. RF welding also yields robust hermetic seals that are very airtight and pass peel, leak, and optical tests. RF welding can also be performed on most common materials, such as:
RF welding and heat sealing are often used interchangeably, with some RF machine manufacturers going so far as to refer to some of their machines as “heat sealers.” In reality, this is incorrect, as heat sealing is the process of sealing one thermoplastic to another similar thermoplastic using a combination of external heat, and pressure. Although both involve heating up molecules within materials, RF welding doesn’t require an external heat source. Thus allowing the material to be more evenly heated and allowing better consistency in addition to being able to weld thicker materials together.
