Rotary RF Welder

Rotary RF Welder - Universal Applications


Rotary RF Welding System

We developed the original rotary RF welder, RF-Roto-L1 with 20"x44" seal area for manufacturing curved tourniquet cuffs ranging from 18" to 44" long sizes. Our customer had experienced many issue with past RF sealers, misalignment, hi-energy costs, long changeover times and process variations, on top of that we had given a tight schedule. We had all under control, yet we had to build the RF welder to prove the capabilities. Our team got to work and the 1st RF welder was ready in 4 months, it produced perfect cuffs with excellent process control using our 10KW hybrid generators. We just installed our 3rd RF welder for the same customer it took us 1 day to install and RF weld some models, the 2nd day we were doing the DOE runs. We can give you an excellent service and support just follow the links to learn more about the system specs and contact us for questions or evaluation. We offer many sizes of rotary RF welders, also check out the standard RF-Roto-M1 with 20"-30" seal area.

Rotary RF Sealer with Print Station

RF Sealers for solution bags with print


Rotary RF Sealer with Print Station

The original RF heat sealer, HSDC-Rroto-X2 was designed to seal ostomy bags and die cut the sealed bag in the second station, using 20T press cylinder. The ostomy bags were produced for Japanese market and had to be precisely cut around the perimeter. The bags were RF heat sealed with great process control and we were able to produce uniform cut bags because of the special toggle mechanism, which aligned the bottom sealing dies under the RF heat sealing and Die cutting stations. We then designed new platform, replacing the die cutting station with a thermal printing station and introduced the RFPS-Roto-X2 RF welding and printing machine with 15"x18" seal area. We recently introduced a new design which is capable of RF welding inlet and outlet ports in two separate cycles before welding the perimeter. With this system we had to RF weld rigid PVC ports to the PVC film and maintain the design integrity. We successfully completed the machine which was used to produce urinary collection bags. This type of RF welding equipment is the perfect solution for RF welding medical solution bags with printed info on the bag in a single pass. Eliminate material handling costs using small footprint and excellent process control.

RF welder with singe shuttle

RF Welder with a Single Shuttle


Single Shuttle RF Sealers

ONEX RF offers several single shuttle RF sealers with wide range of seal areas. The smallest RF sealer with 10"x20" seal area, the RF-Shuttle-S1, was developed for RF sealing ports and flanges on the air bladders and small medical pouches. The mid-size RF welder with 20"x30" seal area, the RF-Shuttle-M1  was developed for sealing blood collection bags, air bladders, for tennis show manufacturer and seat caution air bladders. The same Mid-size RF sealing station is used in the automated  sealing lines as a standalone RF sealing station. The largest RF welder in this family with 20"x60" seal area, the RF-Shuttle-L1  was developed for sealing Tourniquet Cuffs ranging from the smallest 12" cuff to the largest 56" long cuffs.
