Radio frequency welding (also known as dielectric welding, RF sealing, RF welding and RFW) is a plastic welding process that many different industries rely on for the manufacturing of their products. It’s a sealing method that creates an airtight and watertight seal, and is even stronger than the original materials used. It’s clear that with such a process, reliable machines are needed to work with the materials and seal them together, but what types of machines are they, and how do they work exactly?
Equipment Used in Radio Frequency Welding
There are several types of heavy-duty machines that are part of the RF welding process, and each application requires a different type of machine. Products that utilize RF welding in their fabrication include:
- Plastic car parts and fittings
- Stationery items
- Truck curtains, tarpaulins, tents & covers
- Blister packaging
- Medical bags
Of course there are many other products that utilize radio frequency welding, and the machines that form these seals come in many different models, each with a different function.
For instance, seat covers in cars will need welding machines that handle the specific materials involved, such as vinyl, while plasma and blood bags at medical facilities will need machinery that can weld PVC materials. Different sizes of materials also require different types of machines.
Searching for the Right Equipment
When companies offer radio frequency welding services, it’s important for them to utilize the right equipment that can handle the various products produced. Customers should be able to know that each product is constructed using the latest RF welding equipment that is specifically designed for that product.
Future posts here will be devoted to looking at the exact functions of the many machines, as well as the function of options such as coaxial feeds and sealing attachments.
