Custom Medical-Grade PEEK Tubing – Precision Extrusion Capabilities

Introduction

High-performance interventional devices require components extruded to absolute geometric consistency. PEEK (Polyetheretherketone) requires precise thermal control during processing due to its high melting temperatures and tight crystallization windows.

PT&C specializes in the precision extrusion of medical-grade PEEK tubing. Leveraging specialized extrusion lines and advanced melt-processing control, we translate medical-grade PEEK resins into tight-tolerance tubing, supporting your project from rapid prototyping to ISO 13485-certified volume production.

Our PEEK Extrusion Capabilities

Our extrusion technology allows us to achieve strict dimensional control and versatile profiles for medical PEEK applications.

1.1 Dimensional Tailoring & Tight Tolerances

• Inner Diameter (ID) – Custom sizing ranging from $0.35\text{ to }3.5\text{ mm}$ ($0.0138\text{ to }0.1378\text{ inch}$).

• Outer Diameter (OD) – Custom sizing ranging from $0.5\text{ to }4\text{ mm}$ ($0.0197\text{ to }0.1575\text{ inch}$).

• Wall Thickness – Sizing options ranging from $0.1\text{ to }0.8\text{ mm}$ ($0.0039\text{ to }0.0315\text{ inch}$) to balance internal clearance and burst strength.

• Precision Extrusion Tolerances – Strictly controlled within $\pm 0.03\text{ mm}$ ($\pm 0.0012\text{ inch}$) across the production run, ensuring part-to-part consistency.

1.2 Profiles & Co-Extrusion Options

• Multi-Lumen Configuration – Capability to extrude single-lumen, dual-lumen, or multi-lumen designs with stable inner walls.

• Geometric Cross-Sections – Tooling design available for D-shaped, oval, and custom-profiled configurations.

• Co-Extrusion Options – Capability to co-extrude PEEK with embedded radiopaque stripes or multi-layer jackets for specialized delivery systems.

1.3 Material Compounding & Melt Control

• In-Line Compounding – Extrusion of PEEK compounded with barium sulfate ($BaSO_4$) or bismuth trioxide ($Bi_2O_3$) for required radiopacity.

• Thermal Management – Closed-loop temperature control prevents material degradation, ensuring the extruded tubing retains the inherent mechanical strength and bio-inertness of the PEEK resin.

Quality Assurance & Process Control

To ensure compliance and consistency in medical manufacturing, our PEEK extrusion lines integrate continuous monitoring systems:

• In-Line Laser Micrometers – Non-contact OD and wall thickness tracking during the extrusion process.

• Concentricity Management – Real-time centering alignment to optimize wall uniformity and pressure resistance.

• ISO 13485:2016 Certification – Full traceability of extrusion processing parameters and resin compliance certificates.
