RF Welders and Catheter Tipping Systems

When planning a catheter development or production program, real production output is often underestimated. Many teams focus on advertised cycle time or early feasibility results, only to discover later that their actual daily throughput falls short of program needs.

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.

At ONEX RF, we recently developed a process to taper and bond 9Fr PEBAX catheter sheaths using RF —a material known for its flowability and need for precise temperature control. In this case study, we share the tooling setup we used for our CTF-807-LXS1 RF tipping system, process parameters, and...

PVC is a widely used catheter material thanks to its ease of processing, flexibility, and cost-effectiveness. When forming angled tip radii, precision in tooling design and process control is critical to achieving smooth inner and outer radii without compromising lumen integrity. This case study...
