PTFE Mandrel
PTFE Mandrel is a precision forming tool used during the manufacturing of medical catheters and flexible medical devices.
Made from high-quality PTFE material, the mandrel provides a smooth surface, low friction performance, and excellent chemical resistance, helping manufacturers achieve accurate catheter dimensions and easier removal after forming.
We provide customized PTFE mandrels with different diameters, lengths, and tolerances according to customer requirements.
Product Features
High Purity PTFE Material
Made from high-quality PTFE resin with excellent chemical resistance and thermal stability. The smooth PTFE surface helps reduce friction during catheter forming and removal.
Precision Dimension Control
Manufactured with precision extrusion and machining processes to maintain consistent diameter, straightness, and surface quality.
Customized dimensions are available according to different catheter designs.
Excellent Surface Smoothness
The naturally low-friction surface of PTFE helps reduce sticking during forming processes and allows smoother mandrel removal after catheter manufacturing.
How Does a PTFE Mandrel Work?
How Does a PTFE Mandrel Work?
During catheter manufacturing, the PTFE mandrel is inserted inside the tube structure as a temporary support core.
After the forming process, the mandrel is removed, leaving a smooth and accurate inner lumen.
Applications
Catheter Extrusion
Used as a forming core during the extrusion of medical tubing and catheter shafts.
Minimally Invasive Device Manufacturing
Suitable for guide catheters, delivery systems, and other flexible medical device components requiring precise internal dimensions.
Custom Medical Device Development
Used in prototype development and small-batch manufacturing of customized catheter designs.
Why Choose PTFE Mandrel?
Low Friction Surface
PTFE has one of the lowest friction coefficients among engineering plastics, helping reduce resistance during removal.
Chemical Resistance
PTFE is highly resistant to most chemicals and maintains stable performance during thermal processing.
Smooth Inner Lumen Formation
The smooth mandrel surface helps create clean and consistent internal catheter channels.
Custom Sizes Available
Diameter, length, tolerance, and surface requirements can be customized based on customer drawings.
