When it comes to RF welding, there are a number of different materials that lend themselves well to the process. Of course, not every vinyl or flexible plastic product manufactured uses RF welding. So how can you determine whether the product you need manufactured is suited for radio frequency welding? There are a few things that radio frequency welded products all have in common. One, is the materials used and another, is that they typically are flexible.
What Materials Are Suitable for RF Welding?
RF welding can be performed on a range of flexible materials. Materials that contain a polar molecular structure are necessary for the radio frequency welding process. These molecules are rearranged in the welding process and meld together to create the seams that allow custom shapes to be configured. The process of RF welding applies high frequency (13 to 100MHz) electromagnetic energy and pressure to polar materials, causing molecular oscillation and subsequent temperature increase, melting, and finally, fusion of the two materials into a single, minimally visible seam. Vinyls (PVC), polyamides (PA) and thermoplastic urethanes (TPU) can he used with radio frequency welding, as the energy applied can be localized and controlled.
Do You Need Precise and Consistent Measurements?
Radio frequency welding is ideal for creating products that require consistency in measurements as well as precise seams, but is also a process that can be used on much larger items that do not require such precision. For example, radio frequency welding is often used to manufacture large tarps or industrial curtain walls, where the measurements can afford to be within a certain size but are not required to meet extremely specific dimensional tolerances.
Is a Leak-Proof Seal Necessary?
Radio frequency welded items are all created to have strong, consistent, and leak-proof seams, which makes them ideal for use in a number of different industries. The bond formed by RF welding is strong enough to withstand a substantial (relative to the application) amount of wear and tear, and is also water and airtight.
The products created by RF welding cover various industries and include such products as preconditioned hoses for humidity and temperature control, medical containment bags for fluids, paint overspray enclosures, and much more.
Custom measurements and shapes can be accommodated when manufacturing items using RF welding. To learn more about the process and to find out whether your product is an ideal match for the procedure, contact us today.
