Dies and Mandrels for PTFE Paste Extrusion – Precision Tooling by PTFE Tech
Importance of Dies and Mandrels in PTFE Paste Extrusion
In PTFE paste extrusion, the die and mandrel are the most critical components that directly affect the quality, thickness, and surface finish of the PTFE liner or PTFE tube. The PTFE paste is extruded through the controlled gap between the die and mandrel.
This gap determines the wall thickness of the PTFE liner.
A precisely maintained gap ensures uniform thickness, high concentricity, and smooth extrusion flow.
Accurate tooling leads to better mechanical properties, dimensional stability, and reduced material waste.
