RF Welding Systems with Superior Process Control

Rotary RF Welder for Standard Products

RF-Roto-M1 20"x30"

The standard Rotary RF sealer, RF-Roto-4-M1 with 20"x30" seal area, was developed for RF Sealing TPU air bladders with ports and PVC, EVA film medical pouches. This RF Sealing platform is expandable to operate with 2 or 3 RF-Seal stations. Read more about the specs and RF Sealing applications below...

Rotary RF Welder Uses

The standard rotary RF sealer is perfect for sealing medical and automotive products with greater precision. Whats unique about this RF sealing platform is that the Indexer and the RF sealing press are built on a single frame. Everything is perfectly aligned at the factory and drop shipped at customer site. It takes only couple hours to install the dial and test the system making sure the RF generator and controls are set to run based on factory set parameters.

  • No missalignments no headaches.
  • Safe & easy to operate

The RF Sealer comes with closed loop process control to achieve consistent results in RF sealed products.

RF Welding Process Control

Easy - Reliable - Streight Forward.

ONEX RF has developed process control, which makes process validation easy and repeatable.

The closed-loop process control, real-time seal-process monitoring with data logging, helps you set process parameters and achieve acceptable quality seals in a matter of minutes. The hybrid generator uses an AGC to maintain exact RF power at all times, which eliminates process variations during validation.

RF Sealing TPU Air Bladder and PVC Medical Pouches

When sealing ports on air bladders and medical pouches the RF sealing dies have to be properly aligned and indexing dial must be perfectly centered on all 4 nests. We have built several rotary RF welders for welding automotive and medical products and amazingly our systems have proven to be the best, based on our customers' feedback.
