RF Welding and Die Cutting a TPU Cold-Pack Pouch

TPU Cold Pack

Customer Requirements:

Customer was manufacturing different size TPU pouches for various applications TPU Cold Packs, TPU surgical instrument pouches using an RF welder and Die cutting machine afterwards. Every time they changed the setup they had to spend 2-3 hours to get the RF sealer produce good quality seals. 

They asked us to design a system to reduce the change over time and combine the die cutting operation.

ONEX RF Solution:

We provided the following systems:

  • RFDC-Roto-X4 / Rotary RF Welder to seal the perimeter and Die cut station with 20T hydraulic press to cut the excess material around the perimeter.
  • Customer was able to quick change the dies and manufacture 5 different style pouches and reduced setup time from 3 hours to 30 minutes.
