Solid-state RF welding for polymers
Repeatable, high-quality welds for medical bags, technical textiles and industrial covers. Solid-state radio frequency (RF) power with precise digital control and no vacuum tube to replace.
RF welding for blood-bag production
The primary medical segment
Blood bags, IV and drainage bags, medical tubing and pouches are sealed by RF welding. In radio frequency plastic sealing, the RF field heats the polymer from the inside, exactly where the films are pressed together, so the seal forms without heating the whole part.
In RF welding for medical bags, every seal has to be identical, batch after batch. SolidWatts solid-state RF systems control RF power digitally and precisely, and impedance matching adapts to the load, for repeatable welds and a process you can monitor and document.
- No vacuum tubes: less maintenance and downtime
- Precise digital power control for consistent seal quality
- Impedance matching that follows changing loads
- PLC control and process monitoring for automated lines
Retrofit your tube welder
Already running RF welders with vacuum tubes or triodes? Our solid-state RF systems are designed to replace the tube generator in an existing RF press. Some work may be needed on the matching network, and we work with you to make the RF generator retrofit easy.
You keep the press and tooling you know, and gain a long-life solid-state RF power source with precise power control, starting with a single 1 kW module.
