Processing Technology
| Process Step | Core Parameters / Precautions |
|---|---|
| Material Pre‑treatment | TPEE shall be fully dried before processing. Recommended drying at 80~120℃ for 6‑8 hours to keep moisture content ≤0.1%. |
| Injection Molding | • Barrel temperature: Normally 180 • Mold temperature: Recommended 30 • Injection pressure: 80‑120 MPa. • Injection speed: Slow‑to‑medium injection speed. • Screw: Compression ratio (3.0‑3.5):1, L/D ratio (18‑24):1 is recommended. |
| Extrusion | Processing temperature is set slightly above melting point, e.g. 200~250℃. Conventional gradient‑type screw is adopted, L/D ratio ≥24:1 is recommended. |
