No matter the industry in which they’re used, air tight and water tight seals have to be perfect. Any time you are unhappy with sealed products, either because of failing to meet EPA standards or because they aren’t resisting damage, it might be time to take advantage of the excellent technology behind radio frequency welding. Also known as dielectric sealing, this is a process that can be used for many products that require protection against contamination, whether it’s aircraft, medical or manufacturing needs that require a strong, impenetrable bond to containing dust, air, gas and fluids.
