RF Welding Systems with Superior Process Control


Large Rotary RF Welder

RF-Roto-L1 20x40" Seal Area

The large Rotary RF welder, RF-Roto-4-L1 with 20"x40" weld area, was developed for RF welding the stiffener and perimeter of curved Tourniquet cuffs and long air bladders. Read more about the RF welder specs and applications below...

Rotary RF Welder Uses

The Rotary RF welder is a heavy duty RF welding machine with two 6" bore air cylinders. What's unique about this sealer is the even RF energy distribution accross the product surface. Also the RF Welding press and the Indexer are built on a single frame. Everything is perfectly aligned at the factory and drop shipped at customer site.

  • Easy to setup the die from the back

  • Safe to operate

The RF Sealer uses 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 Welding Applications on the RF-Roto-L1 20"x40"

Rf Welded Arm Cuff
RF Welded Tourniquet Cuff

RF Sealing the Stiffener and Perimeter of the Tourniquet Cuffs

ONEX RF has developed complete manufacturing process for RF sealing Tourniquet cuffs, the project included design and manufacturing of the stiffener and perimeter RF sealing dies for cuff sizes ranging from 12" to 44". We also provided the port RF seal station (RF-Shuttle-S1). ONEX developed the RF welding process parameters for all the cuff sizes.

RF welded Knee Brace

RF Welding Pressure Cuffs and Knee Braces

ONEX RF has developed turnkey solution for a contract manufacturer to produce pressure cuffs and orthopedic products. The Air bladders were 3 sizes small medium large and the knee brace included some pressure bladders for support. Both products just required flat perimeter seal. The ports were welded on another RF Welding system.
