RF Welding Systems with Superior Process Control


RF Sealer for RF Sealing Ports and Pouches

RF-Shuttle-S1

The small RF sealer with 10"x20" seal area, was developed for RF Sealing tubing ports on the solution bags and RF seal flange ports on the air bladders. The sealer also was used to seal freezing bags and small medical pouches in the R&D lab. Read more about RF Sealing applications below...

RF Sealer's Uses
.

The small RF sealer is perfect development tool for R&D Lab or product design engineers. It is very easy to use for RF heat sealing various materials and small pouches. The Lab model comes with optional Heat Sealing Capability.

  • Easy to setup
  • Safe 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.

ONEX RF uses Allen Bradley PLC and PC based 12"  HMI to control the RF Welding Machines.
We have designed our systems for ease of use and validation to comply FDA requirements.
We offer validation support, including FAT & Installation Qualification documentation.

RF Sealing Applications on the RF-Shuttle-S1

RF Sealed Elbow Flange.jpg

RF Sealing Flange Ports on the Tourniquet Cuff

The Flange is usually RF Sealed on top or bottom of the film surface. The RF sealing dies come with a cavity to load the straight and elbow flange ports. Operator places the material over the die and installs the flanges into the die cavity through the film layer. Operator extends the shuttle slide under the sealing press to start the RF sealing cycle. The process usually requires 700-1000 watts of RF power to seal 4 PVC flanges to TPU material. If the materials are different the process must be well balanced since the bond is not homogeneous. If you have questions about the process please contact us for application help.

RF Sealing PVC tubing (bushings) between the solution bag film layers

The port sealing requires a dual RF seal cycle switch. The ports are loaded onto a mandrel (SS rod) and placed between the PVC film layers. The first RF Seal cycle is to seal the tubing to the top and bottom film layers and second cycle is to seal the sides or perimeter of the bag. The RF switch is to switch the RF power first to the mandrel and second to the top die, the bottom RF sealing die is usually connected to the ground.
