Catheter Trimming: Methods, Challenges, and the Role of Automation in Modern Catheter Manufacturing

Explore the critical role of catheter trimming in medical device manufacturing, focusing on methods, challenges, and automation's transformative impact.

🔵When forming catheter tips using PVC, success really comes down to getting the heat and material flow right.

In this project, we worked on a 21FR PVC bullet nose catheter and ran into a couple of challenges early on. The material was sticking to the die, and the tip shapes were inconsistent.

Using our Dual Air Tipper, we made a few key adjustments. We applied mold release to prevent sticking, positioned the coil to only heat the start of the taper and slight overinserted the tube to ensure enough material filled both the outer shape and the inside of the tip.

As a result, 99% of the 60 tested samples met requirements, with fully formed tips and no bubbles or voids.

It’s a good reminder that when working with PVC, small process tweaks can have a big impact on consistency and quality.

April 20th was a day of celebration at ONEX RF! 🎉

We just acquired a technology, which made it possible to make our first in-house complex , for flashless tipping application. 🔩

Until recently, we were able to make basic mandrels, and some complex ones we would farm out to a local partner company, which could take as long as 4 to 8 weeks due to workload or high-tolerance requirements ⏳

We are happy to share our excitement and commitment to faster lead times, by slowly ramping up our mandrel production and the ability to manufacturing them in 2-3 weeks, same as our catheter tip-forming dies 🚀

Isn’t this wonderful?

🔵 We not only build your catheter tip-forming machines but also design the dies.
Everything is designed and manufactured in-house, so we understand and control the exact tolerances.

✅ No third-party delays. No material compatibility issues.
Dies are built and tuned with the coil to match the customer's requirements from the start.

✅ No back-and-forth. No adjustments on your floor.

We can produce your die in less than 3 weeks.

Just send a drawing or a sample —we’ll take it from there.

🔵 Here are some examples of tip formed with the ONEX RF Servo-Tipper-PRO.

The customer had very low yields and the challenge was the material buckling, due to softness and even heating the material without burns or bubbles when using narrow heat zone coil, fixed force and fixed position .

The slightest variation in Catheter material, diameter or durometer plus tubing wall thickness, can affect how tubing behaves during the forming process.

Hence the need for the new ONEX Servo-Tipper-Pro, which was developed to overcome the challenges above, using Direct Force Feedback to monitor and control force during the forming process, helping reduce over-insertion, preventing buckling, and improve tip-forming consistency.

The word “catheter” also has its meaning 📖
