Large Dual Shuttle RF Welder Uses
The RF sealer is a heavy duty RF sealing platform with two 6" bore cylinders capable of applying 4000lb of force onto the product. What's unique about this sealer is the even RF energy distribution accross the product surface. The upper platen is supported by 8 adjustble leveling points, which gives you best possible paralelism to achieve perfect RF seal thickness arround the perimeter.
  • 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 Sealing the Stiffener and Perimeter of the Tourniquet Cuffs

ONEX RF has developed complete manufacturing process for RF sealing Tourniquet cuffs, The process included designing the RF sealing dies for Stiffeners and Perimeter of the cuffs. The cuff sizes ranged from 9" to 56" long cuffs. The line also included the Flange RF Sealer (RF-Shuttle-S1). ONEX engineering team also developed the RF sealing parameter for all the sizes and supported the customer during validation.
