Engineered for mission-critical automotive tubing, medical catheters, micro-ducts, and corrugated conduit manufacturing.








Polyamide (PA6, PA11, PA12) processing represents one of the most demanding polymer extrusion engineering sectors due to sharp melting curves, rapid crystallization, and extreme hygroscopic sensitivities.
Processing engineering nylon demands specialized L/D screw profiles (typically 28:1 to 32:1) equipped with barrier zones and customized shear geometries to avoid thermal degradation and melt fracture while ensuring absolute melt homogeneity.
Unlike standard polyolefins, nylon's rapid crystallization necessitates multi-stage immersion vacuum calibration tables with precision water temperature control (±0.5°C) to prevent ovality and relieve internal frozen-in stress profiles.
Advanced spiral mandrel or pancake dies allow laminar multi-layer distribution (up to 5 or 7 layers) including EVOH barrier cores, tie resins, and conductive inner coatings designed for ultra-low hydrocarbon fuel permeation limits.
Why Tier-1 automotive and fluid transport component manufacturers are re-engineering their extrusion infrastructure.
Electric vehicle (EV) battery packs and electric drive units require intricate cooling lines. PA12 and PA612 lightweight corrugated and smooth hoses are systematically replacing heavier aluminum and EPDM rubber hoses across Europe and North America.
With Euro 7 and EPA Tier 4 standards mandating near-zero evaporative emissions, multi-layer fuel systems (e.g., PA12/Tie/EVOH/Tie/PA6) require razor-thin, perfectly concentric barrier layers extruded at speeds exceeding 60-80 meters per minute.
Scrap minimization has become non-negotiable amid rising raw nylon prices. Modern extrusion lines incorporate ultrasonic 360-degree wall thickness scanners and dual-axis laser OD gauges directly communicating with servo pullers.
