Injection‑Molding Parameters
| Process Parameter | Reference Range | Remarks & Instructions |
|---|---|---|
| Drying Treatment | 80°C, 2‑4 hours | Keep hopper heated to prevent re‑moisture absorption; ensure moisture content below 0.1%. |
| Barrel Temperature | Rear zone:180‑200℃ Middle zone:190‑210℃ Front zone:200‑220℃ Nozzle:200‑230℃ (do not exceed 240°C to avoid material degradation) |
‑ |
| Mold Temperature | 40‑80℃ (commonly 50‑60℃) | Higher mold temperature improves surface gloss and reduces internal stress. |
| Injection Pressure | Adjust according to flow length and part structure | May be properly reduced for high‑flow grades. |
| Holding Pressure | Approx. 30%‑60% of injection pressure | Optimize per wall thickness and structure to reduce internal stress and shrinkage. |
| Injection Speed | Medium or medium‑high speed | High‑speed improves gloss yet may cause flow marks; adopt slow‑to‑fast profile for high‑appearance requirements. |
| Screw Speed | Proper speed for uniform plasticization (e.g. 50‑80 rpm) | ‑ |
| Back Pressure | 0.5‑1.0 MPa | Facilitates uniform plasticization and degassing. |
