PTFE Compression Stand
Ultrasonically welding a PTFE Membrane to PVC
PTFE Blood Filter

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.

PTFE Blood Filter

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.
