Injection Molding Parameters
| Processing Item | Recommended Range / Operating Points | Notes & Explanations |
|---|---|---|
| Pre‑drying | Mandatory drying. Dry at 120 °C for 3‑5 h; maximum 140 °C within 4 h. | Critical for processing. Pellets absorb moisture rapidly after opening. Insufficient drying causes silver streaks, bubbles and hydrolytic degradation with reduced molecular weight. |
| Barrel Temperature | Melt temperature:310‑330 °C. Rear zone:310‑320 °C；Front zone:320‑330 °C. | Ensure full melting and good flowability. Avoid long‑term temperature above 330 °C to prevent thermal degradation. |
| Mold Temperature | 130‑150 °C. | High mold temperature improves surface gloss, reduces internal stress, promotes crystallization and stabilizes dimensional accuracy. |
| Injection Pressure & Speed | Medium‑to‑high injection pressure; medium‑high injection‑speed recommended. | Good flowability supports fast filling for thin‑wall parts; adjust parameters according to product geometry. |
| Back Pressure | 5‑15 bar recommended. | Realizes homogeneous plasticization and degassing. |
| Screw Speed | Medium rotation speed. | Excessive shear force will break glass‑fiber and induce local overheating. |
