Radio Frequency Welding is used to fuse together materials by applying Radio Frequency Energy to the area needing to be joined. The resulting weld is often as strong as the parent material and can create a completely water tight seal.
Two or more sheet materials can be joined to make profiles and shapes to suit exact Customer specifications. The welding tool can be engraved or profiled to give the entire welded area a decorative appearance or it can incorporate an embossing technique to place lettering, logos or decorative effects on the welded items.
A cutting edge can also be incorporated adjacent to the welding surface allowing a simultaneous weld and cut. The cutting edge compresses the hot plastic sufficiently to allow excess scrap to be torn away. This process is often referred to as tear seal welding.
Typical Applications where Radio Frequency Welding are used include:
-
Stationery – Book Covers, Stationery Wallets, Zip Bags, Binders and Office Files.
-
Construction – DPC Profiles.
-
Medical Items – Blood Bags and Colostomy Bags.
-
Inflatable Items – Beach Balls, Toys, Air / Water Beds, Rafts and Life Jackets.
Applique Welding is the process of joining additional pieces of material onto the surface of a product for ornamental purposes.
The most common materials used in Radio Frequency Welding are Thermoplastics such as PVC and Polyurethane. It is also possible to weld other polymers such as Nylon, PET, EVA and some ABS Resins.
