Injection Molding Parameters
| Parameter | Setting Range | Optimization Suggestion |
|---|---|---|
| Drying condition | 80‑85℃ × 2‑4 h | Moisture ≤0.05% to avoid silver‑streaks & bubbles |
| Barrel‑rear temp. | 180‑190℃ | Segment temperature control to prevent degradation |
| Barrel‑middle temp. | 200‑210℃ | |
| Barrel‑front temp. | 210‑220℃ | |
| Nozzle temperature | 215‑225℃ | |
| Mold temperature | 50‑70℃ | Above 60℃ for better surface gloss |
| Injection pressure | 60‑100 MPa | Higher value for thin‑wall parts |
| Hold‑on pressure | 40‑60% of injection pressure | Avoid excessive hold‑on for internal‑stress reduction |
| Back pressure | 0.3‑0.7 MPa | Proper back‑pressure for uniform plasticization |
| Injection speed | Medium‑high speed | Fast filling to reduce flow marks; multi‑stage speed for complex geometry |
| Screw speed | 40‑70 rpm | Prevent shear‑overheating degradation |
| Cycle time | 20‑50 s | Adjust by wall‑thickness; cooling time accounts for 60% |
