Two-Color Medical Silicone Tubing Co-Extrusion
Key Capabilities
- Can be used for processing medical-grade solid silicone.
- Produces two-color and multi-lumen silicone tubing, while typical products include two-color identification tubing, radiopaque-line silicone tubing, double-layer composite tubing, and color-striped tubing for visual identification.
- Dual servo-driven extruders operate in electronic synchronization, with real-time closed-loop melt pressure compensation. A pressure-stabilized co-extrusion head works with PLC-based three-loop coordinated control to maintain a consistent material flow ratio and uniform color identification without width variation or misalignment.
- The screw and barrel are made of 38CrMoAlA nitrided steel, while the extrusion head and die use S136 corrosion-resistant mirror-finished tool steel.
- Both extrusion systems feature independent multi-zone closed-loop temperature control with an accuracy of ±0.5 °C.
