Injection Molding Parameters
| Process Parameter | Reference Range / Recommendation | Remarks & Descriptions |
|---|---|---|
| Drying Treatment | 80°C for 2‑3 hours | PS has low moisture absorption (less than 0.2 %); drying is generally unnecessary. Drying is recommended under improper storage conditions. |
| Barrel Temperature | 180‑280°C (preferably 185‑215°C) | Upper limit for flame‑retardant grade is 250°C; decomposition temperature is approx. 290°C. |
| Mold Temperature | 40‑80°C | Higher mold temperature improves part gloss and reduces internal stress. |
| Injection Pressure | 200‑600 bar | Subject to part geometry and wall thickness. |
| Injection Speed | High injection speed recommended | High injection speed is preferred especially for complex‑shaped and thin‑wall parts. |
| Screw Speed | ‑ | Avoid excessive screw speed to prevent shear overheating or material degradation. |
| Runners and Gates | All conventional gate types are applicable | ‑ |
