Radio Frequency Welding of Single-Use Devices
Advantages of RF Welding Medical Devices for Manufacturers & End Users

As OEMs help their healthcare and life sciences clients improve manufacturing of single-use products, you might find yourself scrambling to replace traditional materials with eco-friendly alternatives while ensuring your medical device remains profitable and effective. Just as challenging, many manufacturers are unable to achieve successful welds of certain materials for patient use. Let’s discuss the advantages of RF welding medical devices.
When you partner with Genesis Plastics Welding, our proprietary Radio Frequency (RF) Welding of plastic products means your device will be far superior in its quality, durability and sustainability. Just as important, you’ll find a more efficient manufacturing process for custom medical device products and expanded design options, thus producing a better product. If you can draw it, we can weld it.
In all, RF welding benefits are plenty:
- More efficient processing.
- Improved quality.
- Eco-friendly alternative to toxic solvents and materials.
- Potential reduction of raw materials.
- Tighter, permanent bond as strong as the original material, translating into greater resilience.
- Greater process control with more complete, leak-proof welds.
- Safer option for patients with skin sensitivities to conventional materials (PVC, latex).

Common Alternatives to RF Welding
How does RF welding compare to conventional options?
RF Welding
Sonic works better with rigid components
Sewing: When stressed, threads can break under pressure, putting patients at considerable risk.
Gluing: Adhesives use hazardous solvents, harmful to the environment. They also wear out, and seams can eventually fail. Gluing also takes much longer than RF welding.
Hot Air: This method applies heat to the outside of the material to melt it and create a bond. This will not work for materials that are too thick, as the outside layers overheat and burn while the middle struggles to melt.
Common devices
Medical devices your peers have entrusted to Genesis’ RF welding include medical fluid delivery, storage and drainage bags, among others. View the gallery.
