Injection Molding Parameters
| Processing Item | Recommended Range / Operating Points | Notes & Explanations |
|---|---|---|
| Pre‑drying | Mandatory drying. Dry at 100‑120 °C for 4‑8 h. | Moisture content shall be controlled below 0.1%, to prevent molecular‑weight reduction caused by hydrolysis and defects such as silver streaks and bubbles. |
| Barrel Temperature | Melt temperature range:310‑330 °C. | Key processing parameter. Low temperature results in poor flowability; excessive temperature triggers degradation. Residence time inside barrel shall not exceed 10 minutes. |
| Mold Temperature | 80‑120 °C, minimum 80 °C 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 suggested. | Ensure complete mold filling. |
| Injection Speed | Medium speed. | Excessively high speed causes jetting marks; too‑low speed leads to insufficient filling due to melt‑front cooling. |
| Back Pressure | 2‑10 bar. | Promotes melt homogenization, while excessive value generates extra shear heat. |
| Screw Speed | Medium rotation speed. | Avoid excessive shear force which may break glass‑fiber and cause material degradation. |
