Injection‑Molding Parameters
| Process Parameter | Reference Range | Remarks & Instructions |
|---|---|---|
| Drying Treatment | 75‑80°C, 3‑4 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 | Feed zone:170‑180℃ | Compression zone:180‑200℃ | Metering zone:180‑210℃ | Nozzle:180‑210℃ | Prevent material degradation; avoid long‑term residence of molten material inside high‑temperature barrel. |
| Mold Temperature | 40‑60℃ | Suitable for high‑precision molded parts. Mold temperature directly affects appearance, shrinkage and internal stress of finished products. |
| Injection Pressure | 50‑70 kg/cm² | Adjust according to flow length and product structure. |
| Holding Pressure | 40‑60 kg/cm² | Approx.30%‑60% of injection pressure. Optimize according to wall thickness and product structure to reduce internal stress and shrinkage. |
| Back Pressure | 5‑15 kg/cm² | Proper back‑pressure ensures uniform plasticization and degassing. |
| Injection Speed | High‑speed injection recommended | Beneficial for good surface gloss, color performance and minimizing weld‑lines. |
