Case Study: PTFE Compression Stand
Challenge:
Design a disposable assembly to ultrasonically weld a PTFE membrane to flexible PVC—a difficult material combination—while meeting 21 CFR Part 210/211 compliance for pharmaceutical-grade filtration.
Solution:
Taurus Engineering engineered a single-use compression stand that enables precise ultrasonic welding of PTFE to PVC. This assembly plays a critical role in blood filtration systems, supporting clean, reliable fluid flow in medical applications.
Highlights:
- Materials: PTFE membrane + flexible PVC
- Process: Ultrasonic welding—no adhesives, fasteners, or contamination
- Purpose: Maintains integrity in blood filtration during critical use
- Design: Disposable tooling to ensure sterility and prevent cross-contamination
- Compliance: Built to meet pharmaceutical CGMP standards (21 CFR 210/211)
This project showcases Taurus’ expertise in material science, ultrasonic welding, and turnkey medical device manufacturing.
