Processing Parameters
| Processing Item | Recommended Range / Operation Key Points | Remarks & Instructions |
|---|---|---|
| Pre‑drying | Drying is mandatory. Dry at 100‑120 ℃ for 4‑6 hours. | Moisture content shall be kept below 0.05% to prevent molecular weight reduction caused by hydrolysis, silver streaks, bubbles and other defects. |
| Barrel Temperature | Melt temperature range:310‑330 ℃ | Critical processing window. Low temperature leads to poor flowability; excessive temperature causes material degradation. Residence time inside barrel shall not exceed 10 minutes. |
| Mold Temperature | 120‑140 ℃, minimum 90 ℃ is recommended. | Higher mold temperature reduces internal stress, improves surface gloss and dimensional stability, and ensures sufficient crystallization. |
| Injection Pressure | Adjust according to product structure and wall thickness; medium‑high pressure is recommended. | Ensure complete mold filling. |
| Injection Speed | Medium speed. | Excessive speed may cause jet marks; insufficient speed may lead to short shots. |
| Screw Speed | Medium speed. | Avoid excessive shear force which may break glass fibers or degrade the material. |
