PTFE Capillary Tubing Manufacturing

The extrusion manufacturing method is commonly used to produce PTFE capillary tubing.

The manufacturing process include the following steps:

Raw Material Selection – High-quality virgin PTFE resin and pigments (for colored tubing) are sourced.
Preforming – The PTFE resin is compressed into a cylindrical billet under controlled pressure.
Extrusion – The preformed billet is extruded through a specialized die to achieve the desired capillary tubing diameter and wall thickness.
Sintering – The extruded tubing undergoes a high-temperature sintering process to fuse the PTFE particles.
Cooling & Calibration – The tubing is gradually cooled and precisely calibrated to maintain tight tolerances.
Cutting – Tubing is cut to specific lengths.
Quality Inspection – Dimensional accuracy, surface finish, wall uniformity, and color consistency (for colored tubing) are rigorously tested to meet industry standards.
