Processing Parameters
| Processing Item | Recommended Range / Operation Key Points | Remarks & Instructions |
|---|---|---|
| Pre‑drying | Dry is mandatory. Dry at 120 ℃ for 4 hours. | Moisture content shall be kept below 0.045% to prevent molecular weight reduction caused by hydrolysis, silver streaks, bubbles and other defects. |
| Barrel Temperature | Rear zone：318‑324℃；Front zone：327‑332℃ | Melt processing temperature：329‑343℃. Critical processing window. Excess temperature causes degradation; insufficient temperature leads to poor flowability. Avoid long residence time inside barrel. |
| Mold Temperature | 65.6‑93.3 ℃ (approx.150‑200°F). Hot‑water mold forming is also feasible according to references. | Proper mold temperature reduces internal stress, improves surface quality and dimensional stability. |
| Injection Speed | 3‑4 inch/s | ‑ |
| Holding Pressure | 50% of injection pressure | ‑ |
