Processing Parameters
| Process | Parameter | Unit | Recommended Range | Remarks |
|---|---|---|---|---|
| Pre‑drying | Drying temperature | ℃ | 100‑120 | Dehumidifying dryer recommended; TPU is moisture‑sensitive; insufficient drying causes processing defects & poor performance |
| Drying time | h | 2‑3 | Moisture content＜0.05% | |
| Injection molding | Rear‑feed zone temp | ℃ | 170‑210 | Avoid premature plasticization |
| Middle‑barrel temp | ℃ | 170‑210 | ||
| Front‑metering zone temp | ℃ | 170‑210 | ||
| Mold temperature | ℃ | 20‑70 | Higher mold temp improves surface finish & flowability | |
| Extrusion | Barrel zone temp | ℃ | 160‑210 | Adjust according to melt condition |
| Die temperature | ℃ | 175‑215 | ||
| Melt temperature | ℃ | 170‑210 | Strictly prohibit＞240℃ to prevent material degradation |
