Mandrels for Advanced Catheter Manufacturing

Mandrels are the foundation of every catheter build—and manufacturing efficiency depends on getting that foundation right. PTFE Natural® coated mandrels are engineered to support clean release, consistent performance, and long service life. With optimized lubricity, strong adhesion, and durable coatings, you can reduce fallout, improve yields, and maintain reliable processing from run to run.
