    WHAT IS RADIO FREQUENCY (RF) WELDING?

    RF welding, also known as dielectric welding, uses radiofrequency waves to create an airtight seal between two materials. Across the industrial sector, manufacturers also use the names dielectric sealing, radio frequency sealing and RF welding. These processes use radiofrequency energy to join various thermoplastic films by fusing materials from the inside out. The created seal does not leak air, moisture or other components.

    Dielectric welding and heat sealing are distinct processes with noted differences. RF heat sealing equipment uses a combination of external heat and pressure to create a bond. Dielectric welding does not require an external heating source, allowing for more consistency and creating stronger bonds.

    During the process, the radio frequency excites the molecules in the plastic, causing them to move exponentially faster and generate heat. The heat allows the plastic materials to join together, assisted by pressure coming from a plate or compressor. When the materials cool, they become molten and fuse.

    Several kinds of plastic materials commonly used in the RF welding process include:

    • Polyvinyl chloride (PVC).
    • Polyethylene terephthalate (PET).
    • Low-density polyethylene (LDPE).
    • Polyurethane.
    • Nylon.
    • Cellulose acetate.
    • Ethylene-vinyl acetate (EVA).

    RF WELDING APPLICATIONS

    RF welding machines work well for manufacturing products that require a watertight or airtight seal. Because of the fast welding speeds and the fact that the equipment generally stays cool when functioning, this process is ideal for large-scale production operations. Various industries use radio frequency welding applications for products with unique shapes and sizes.

    Manufacturers prefer dielectric welding for many of their high-volume fabrication needs, from consistent straight welds for tarps, plastic doors and signage to distinct shapes such as tent peaks, water tanks and plastic cylinders. Many companies require multiple technologies for different seams in their manufacturing processes.

    Some typical applications include:

    THE BENEFITS OF RADIO FREQUENCY WELDING

    The RF welding process creates leak-proof seams by combining the strengths of the original materials, making the bond as durable as the original materials. The joint is heavy-duty and highly resistant to tears and rips, resulting in a product superior to conventional bonding methods.

    Dielectric welding is an ideal solution for durable seams in heavy-use scenarios under harsh conditions.  Some of the primary benefits of using dielectric welding equipment include:

    • Lower RF tooling costs: Dielectric welding equipment bonds materials with less power and arcing, creating minimal wear on the dies and platens. Less wear on the tooling means a longer life span with higher quality results.
    • Superior weld strength: RF welding machines can outperform conventional equipment by delivering consistent and controllable output power throughout the process. RF welders produce stronger welds without wasting resources and time adjusting to variable operating conditions.
    • Improved energy efficiency: Radio frequency welding equipment often operates on half the power of tube-style plastic heat sealers. These reduced levels translate to lower utility bills and improved efficiencies that can increase your operation’s bottom line.
