Radio Frequency (RF) Heat Sealing Tools
Radio Frequency, or RF, Heat Sealing dies and tools are used in the sealing and trimming of products created from, but not limited to vinyl, urethane, laminated fabrics, plastic packaging materials and impregnated foams. The tools are produced from stock tear seal brass rule, standard bar stock brass or custom machined, either hand milled or CNC’ed, to fit a customers designs and patterns. Although brass is the most common and preferred material utilized in the construction of these tools, aluminum and steel has been used effectively as well.
 Laminated fabrics, some urethanes and other difficult to tear seal materials require more complex tool known as “articulating dies” or “seal & cut tooling”. Seal & cut dies are a combination of a brass bar seal die with a perimeter secondary cut provided by either a forged cutting die or a pre-sharp die. The equipment used for this operation is usually an “air over hydraulic” heat sealer, which completes the typical pre-seal, seal and cool cycle’s. When the cool cycle is complete the machine kicks in the hydraulic system to compress the brass and trim the final part from the waste.
 By combining our knowledge of cutting dies and RF tooling we have assisted customers who have produced items such as medical inflatables, packaging closures, children’s toys, baby teething products, three ring binders as well as many, many others. In addition to producing your heat sealing tools, we can also offer custom, turnkey packages for tooling and equipment, which allows you to see your product come to life in a Radio Frequency Heat Sealer before ever producing the product on your floor at your facility.
