High frequency (HF) welding method (also known as radio frequency
Common products manufactured with HF welding method are tarpaulins, tents, ceilings, advertising outdoor banners, waterbeds, inflatable boats, drip and blood bags, tensile structures, conveyor belts, rain clothing, etc.
Examples: PVC, PU, PET, PA (Nylon), ABS, TPU, EVA
Tooling (electrodes) is the part of the machine which is pressed onto the materials to perform the weld. Electrode is usually attached to a machine’s upper platen (toolholder). However, if the construction of the workpieces requires it, the electrode can be attached to the lower platen or in the tray.
Electrodes are usually made of brass and aluminum materials. Selection depends on cost, design complexity and durability. Brass is more expensive material, but it’s very durable and easy to repair. It is preferred tooling for large-volume production. Aluminum is low cost material and easy to make, but has a low durability and it is difficult to repair. Aluminum electrodes are good for complex pattern, although they require up to 25% more power than brass tooling to achieve similar weld joint strengths.
The latest version of SIMATIC WinCC software delivered with FIAB welders allows to keep the machines and plant operating at maximum efficiency.
• A/C welding screen (parameters values strongly depend on the type and density of the welded material)
• E/C welding screen (program automatically calculates the energy you need for the specific tool area)
• FIAB Q (allows to record the welding process)
By using the proven SIEMENS Touch Screen control panels, operating our machinery becomes easy and secure and does not require time – consuming trainings. An intelligent, menu-guided user interface is ready to serve our customers in multiple languages.
Unlimited number of welding parameters are stored on a SD Memory Card and can be reapplied for every new welding cycle. The tested and proven welding ‘recipes’ allow to maintain high quality of welding seams and guarantee the increase of productivity.
