RF Welders and Catheter Tipping Systems

When forming catheter tips using PVC, success hinges on mastering heat control and material flow. In this post, we break down how we formed a 21Fr bullet nose tip from PVC using the ONEX RF CTF-807-LXS2—sharing key parameters, setup tips, and the process insights we learned along the way.
