The most common application of RF Welding machine is in factories. It is used in the fabric industries to seal polyurethane and PVC coated fabrics. The process is also commonly used in different kinds of industries where polymer films need sealing. Even sealing equipment and automation systems make use of RF welding. Some of the common products that are sealed using RF welding include inflatable toys, seat cushions, inflatable rafts, bladders of footballs, dust filters, automobile sun visors/tops/doors, sheet protectors, etc.

The fusion of these plastics can be done using a plain old heat sealer also, but the process is much faster when a RF welding machine is used, thus increasing the overall production rate by a decent margin. This is the reason that most factories prefer a RF welding machine to the conventional heat sealer.

In addition to this, when RF welding is used to seal plastic, it cools down quicker, and thus making it safe for handling. The product also comes out of the machine quickly. What’s more, providing a strong leak-proof seal is also possible with this method.

RF welding and sealing makes use of high frequency electromagnetic radiation (radio waves) to excite the molecules in different types of polymers to provide highly localized heating. Major advantages of RF welding include a consistent quality of connection and quick cooling action.

Materials that can be used with RF welding include polyurethane and PVC and polymers like PET, Nylon, EVA, and some ABS plastics.

Generally speaking, an RF welding machine can be used for a variety of applications. Although the technology has been around for over a half-century, RF Welding Machine machines are still common in industrial settings and factories. Currently finding new use in the medical fields, this form of sealing provides a safe, time-efficient way to fuse plastic together.
