Reliable Performance

Tight tolerances to enable consistent diameter and roundness for catheter shaft manufacturing

Material Options

Optinova offers both PTFE and Acetal (POM) mandrels for various manufacturing needs and application requirements

PTFE Benefits

Ideal for small-sized high demanding applications. Low friction and shrinks in diameter when stretched, simplifying superior post-manufacturing mandrel removal. High temperature tolerance makes it ideal for post-processing operations that require elevated temperatures

Acetal (POM) Benefits

Ideal for medium-sized shafts, cost-effective for large volume production and has a smooth surface for easy removal

Customization

Apply additives for durability, lower friction, and other optimizations. Acetal available in single and multilayer options, with multilayer improving dimensional stability, flexibility and roundness

Applications

Manufacturing aid for braided or coil-reinforced shafts
Transport aid of ultra-thin wall delicate extrusions such as
catheter jackets or CRM lead components
