Radio Frequency Welding
Radio frequency welding, also known as high-frequency welding, is a process that fuses materials by applying radio frequency energy to the joining area. When the materials reach a point when the heat melts them, the two surfaces meld together. The result is the materials staying fused with a secure weld.
An ideal radio frequency weld is airtight and will not lose its integrity under the most extreme conditions.
While heat sealing and radio-frequency welding are similar in theory, there are differences. Heat sealing joins materials with direct pressure and heat from a die that contacts the materials. During radio frequency welding, no heat source directly touches the materials.
High-Frequency Welding Applications
Radio frequency welding systems typically consist of a generator and a press. The generator creates the radiowaves that join the materials while the press compresses both melted materials together. Precise pressure levels are essential to achieving an effective weld.
The two most common types of high-frequency welding machines are rotary radio frequency welders and shuttle radio frequency welders. The main difference between these two systems is how the joining materials move through the equipment. Rotary welders use a turntable to rotate the material through the welding station, while shuttle welders depend on a plate to slide the substrate.
The sealing dies in the presses typically consist of brass or aluminum.
Some materials that work well in high-frequency welding include polyethylene terephthalate (PET), polyvinyl chloride (PVC), thermoplastic polyurethane (TPU) and low-density polyethylene (LDPE).
Radio frequency welding is often more efficient in high-volume manufacturing. Several examples of typical applications are:
- Automotive and transportation.
- Industrial-use curtain walls.
- Vinyl binder covers.
- Medical plasma bags.
- Document and filing sleeves.
- Vinyl banners and signage.
- Commercial products.
Benefits of Radio Frequency Welders
High-frequency welding offers several unique advantages over other sealing methods, including:
- Superior seal strength: Radio frequency welding creates a stronger seal than the actual materials. The result is a more durable bond that’s less likely to break, crack or tear apart.
- Exceptional adaptability: Radio frequency welding is a highly adaptable process that can join two different types of materials, while many other sealing applications handle only materials that are similar in composition.
- Airtight security: High-frequency welds are among the most secure options for bonding in manufacturing. These seals are airtight and watertight and are often more durable than bonds from other methods.
- Cold-running equipment: The compression stage of the process works while running cold, providing more control over the weld and creating higher bond strength.
- Lower tooling costs: Our solid-state welding machines seal with lower power and less arcing than conventional welders, meaning the tooling will last longer and provide higher-quality results.
- Increased energy efficiency: High-frequency welders operate on significantly less energy than other types of welding machines, increasing savings on your utility bills.
