Injection‑Molding Parameters
| Process Parameter | Reference Range | Remarks & Instructions |
|---|---|---|
| Drying Treatment | 80℃, 2‑4 hours | AS resin is hygroscopic. Sufficient drying is required (moisture content below 0.1% recommended), otherwise silver streaks and bubbles may occur on finished‑part surfaces. |
| Barrel Temperature | 200‑250℃ | Slightly lower temperature can be adopted for thick‑wall products. |
| Mold Temperature | 40‑80℃ | 50‑60°C for high‑precision parts; 60‑80°C for high‑gloss and high‑heat‑resistance requirements. Mold temperature directly affects appearance, shrinkage and warpage of molded parts. |
| Injection Pressure | Properly increased | AS has slightly lower flowability than PS, so relatively higher injection pressure is needed. |
| Injection Speed | High‑speed injection | Beneficial for good surface gloss, color performance and minimizing weld‑lines. |
| Back Pressure | Moderate back‑pressure | Promotes uniform plasticization and degassing. |
