RF Welding the perimeter of a large blood pressure cuffs

RF Welded Blood Pressure Cuffs

Customer Need:

The customer had issues with material variations and constantly had to tweak the process parameters to get a good quality seal. They had too many rejects and failures of seal integrity.

ONEX RF Solution:

We at first manufactured a sample die and asked them to provide different materials with thickness variations. We then Sealed the products without changing any process parameters. Our customers couldn't believe it.

We provided the following systems:

  • RF-Roto-L4 / Rotary RF Welder with a 20 x 40" upper platen to RF seal the perimeter of the blood pressure cuffs.
