Capacitive resistance welding of plastic films and moulded parts via an alternating high-frequency electromagnetic field that causes the dipoles of the plastic to vibrate, thus heating them:

• High-frequency generators with an output of 1,500 – 40,000 W; stable working frequency of 27.12 MHz.
• Compliance with the international telecommunication authority requirements for frequency-stable, harmonic-free, low-radiation generators.
• Modular design and grid construction make it possible to expand the machines to include additional functions, adapt them to new products and conditions, and to enhance performance.
• Energy-saving process with absolute protection of electrodes (wear-free).
• Very precise work is possible, because only the areas being joined are heated.
• High weld quality thanks to infinitely adjustable pressure and penetration depth.
• Particularly durable weld through cooling of the weld under pressure with the device closed.
• Even welding of different materials through adaptive regulation of the power.
• For plastic parts with dipoles, especially PVC (polyvinyl chloride), but also PA, ABS, linear PUR, CA films with plasticiser additives, CAB and low molecular weight PMMA.

Application examples:

• Office organising materials: Ring binders, file folders, loose leaf binders, clear plastic folders.
• Advertising materials: Pocket calendars, photo albums.
• Packaging materials: Blister packs.
• Medical: Blood bags, dialysis bags.
• Automotive industry: Automobile interior trim.
• Nuclear research: Waste disposal.
• Upholstery industry.
