Job Description

Roles

Responsible for developing, optimising, and validating thermoplastic extrusion processes used in medical and precision tubing applications. This role focuses on process understanding, tooling performance, and material behaviour across a range of TPEs and engineering plastics to ensure dimensional precision, process stability, and consistent product quality.

Requirements:

Hands-on experience in the extrusion or process development of medical-grade thermoplastic products, including but not limited to:
a) Tubing and micro-bore tubing


b) Single-lumen catheter tubing


c) Multi-lumen tubing


d) Multi-layer tubing


e) Multi-material tubing


f) Braid-reinforced tubing


g) Multi-hardness tubing


h) Coil-reinforced tubing


i) Balloon tubing


j) Tapered tubing


k) Profiles and custom profile co-extrusions


l) Co-extrusion structures


Experienced with extrusion systems, downstream processes, and medical-grade thermoplastic materials used in precision tubing and co-extrusion manufacturing.
a) Operation of single-screw, twin-screw, and co-extrusion systems for mono-, multi-layer, and multi-material tubing.


b) Setup and control of vacuum sizing and calibration tanks for OD/ID accuracy and concentricity control.


c) Experience with laser and ultrasonic measurement systems for real-time OD, wall thickness, and concentricity calibration.


d) Processing experience with Thermoplastic Elastomers (TPEs) such as PVC, TPU, TPO, TPV, SEBS, TPE-S, TPE-O, etc.


e) Processing experience with Engineering Plastics such as PEBAX, Nylon (PA 6, 11, 12), PBT, PC, PSU, PPSU, PEEK, etc.


f) Exposure to cleanroom extrusion environments and integration with secondary operations (e.g., tipping, flaring, bonding).


Familiar with multi-lumen and co-extrusion tooling, flow balancing, and pressure management. Strong understanding of melt flow dynamics, die design principles, and extrusion process stability. Experienced in conducting process capability studies (Cp, Cpk). Strong understanding of melt flow dynamics, die design principles, and extrusion process stability. Familiar with multi-lumen and co-extrusion tooling, flow balancing, and pressure management. Able to interpret and apply rheological data, thermal properties, and viscosity profiles. Proficiency in CAD tools (SolidWorks/AutoCAD) and process analysis software (Minitab/JMP). Proficiency in CAD tools (SolidWorks/AutoCAD) and process analysis software (Minitab/JMP). * Experienced within a medical extrusion environment operating under ISO 13485, GMP, or equivalent quality systems, including exposure to process validation (IQ/OQ/PQ), cleanroom manufacturing, and biocompatible polymer processing.
